1979 toyota dolphin battery smells like its over charging low on fluids new alternator new battery, battery isolator bypassed, after two or three days battery dies but if i pull the cable it doesn't die, but still overcharges.
Thanks,

thats what i thought at first so unless it broke off i cant seem to find it any where underneath.thanks derek for the help
-
can anyone tell me where the spare tire was kept originally in a 1979 toy dolphin??
-
you guys got me thinking so i went and checked the pump.i cant read anything except that it says for a 6 cyl.it has the stock carb.i will look for another pump thats better matched to my 4 cyl. thanks
-
i have a 79 dolphin that had a fuel pump problem.i installed an electric pump on the fender well.it does pull fuel through the old pump.my gas guage works.but the gas mileage suffered badly.i now get approx. 12 mpg.but it does run.
-
derek is correct. in the 79 dolphin both batteries were under the hood.the one on passenger side starts the engine the other for the coach.if you plug into 120 volts you can work on it without battery.

Have a look at your fuse panel at the converter and see if there isn't a large black wire attached to a large lug. If so that is your main feed wire to the converter from the battery.
thank you found the problem it was at the converter as you said. all is well in the old palace and will resume my winter fishing trip. larry
-
Fused ground wire? If it's a #8 wire it goes to the converter/charger.
the ground wire has been bolted to the frame and was working fine. the black wire goes all the way to the rear wheel then into the house but i cant find it to continue tracing
-
ok went for a little winter fishing trip and the lights just went out.battery is fine.works when plugged in.traced the wire from the battery to the back wheel area then it disappears into the house and i cant find out where it goes. also rewired the ground connection.i cant find any fuses except the one in the ground wire. its a 1979 dolphin. any ideas??? larry
-
just figured out with some great help from here that i need a 1979 toy dolphin battery isolator. not having much luck locating one any ideas?? thank you larry

If your isolator is a relay type there are no wiring changes as far as the alternator is concerned it's output wire goes to the truck battery through the stock Toyota wiring you could remove the entire set up and the truck battery will still charge. There is a wire that goes to the relay from the truck battery, once energized by the key switch the relay closes and joins both batteries together. If you are indeed having truck battery issues you need to correct that first then move on to the coach battery system. Now that being said if the isolator is solid state it will be a box maybe 3X6" with cooling fins there are 3 or 4 terminals (forget the small one) one will be marked "A " that is the output lead from the alt. one is marked 1 the other 2 they are the battery leads. Usually the #1 terminal is the truck battery but it could be #2 it does not matter they will work fine reversed the other lead is the one for the coach. If you join 1and 2 to the "A" terminal that will bypass the isolator if it has 4 terminals (I do not think the external regulator system needs the 4th wire) the small wire is need to make the isolator work with the alt. but it is not need if you bypass the isolator if it charges then the isolator is suspect. I'm guessing that you have the relay type it's pretty much what they put on most from the factory it's a lot simpler and cheaper set up.
thank you got side tracked for a few days but went out to the toy and bypassed the isolator. it was the one with the fins you mentioned. it now charges the truck battery just fine.will get isolator and be great. again thanks to all that posted. i love this forum larry

1979 toy dolphin battery not charging took alt. to auto parts and tested it twice and its good. both batteries are about brand new.any advice where i look next.someone suggested the regulator but from what ive read so far the isolator has been mentioned.need help on this one thanks larry

I'm not sure about the 1979 as to how it works. Somewhere in that area (1980??) things started to become standardized for the MH manufactures. Well, "Standardized" might be a little strong, "Similar" might be better. i.e. they started using similar appliances and they were basically wired in a similar fashion.
If your looking at the simplified diagram the I posted, this is how my 88 Dolphin "was" wired. Keep in mind that it is "simplified" and doesn't show detail, i.e. circuit breakers, fuses, splices, wire routing, where wires are connected, etc.
Referring to the simplified diagram:
Lights, furnace, stove hood, should run off the converter (or truck) , even if the coach battery is physically disconnected . The Cigarette lighter plug should also run, BUT, this depends on how the Cigarette Plug is physically wired into the circuit.
On my original MH wiring, there were THREE separate ring terminals that needed to be attached to the Battery PLUS terminal (two for the Minus) . A #10 wire terminal that went to the Converter, a wire terminal from a stereo that the previous owner installed, AND, a wire terminal that went to the Cigarette lighter (through a circuit breaker)
Here's my point (and I think your question) - When I disconnected the coach battery and just left the terminals laying in the battery compartment, my Cigarette plug or radio wouldn't work, because they aren't getting power. However, when I disconnected the battery and then attached these three wire terminals together with a small bolt, then everything, including my Cigarette plug and radio worked fine off the converter OR truck power.
On some Toys, the Cigarette plug may be wired a little different, and may work without doing anything special to the battery terminals if they're disconnected.
When I drew the diagram, I thought the way the Cigarette plug was wired was significant. When I installed my TV antenna, I had to change the Cigarette Plug (that's where the TV antenna amplifier is). I spent a couple hours trying to figure out why mine continued to get power, even though I had every 12 volt fuse in the converter removed. That's when I found out it had its own separate wire, and it connected directly to the battery (doesn't go through the converter like everything else) with its own circuit breaker.
Here's what I did when I installed my high power inverter to clean this up and simplify the cables that get attached to the coach battery. I also made the cables a little longer to make servicing the coach battery a little easier.
Inside the battery box compartment, I now have one #4 red cable that attaches to the battery PLUS, and one #4 black cable that attaches to the battery MINUS, thats it, no other cables or wires connect to the coach battery.
These two battery cables are about 3 ft long, and go inside the coach where they attach to the bottom side of 150 amp fuses (you can see this in the link photos. There are two separate fuses, one for the PLUS side, one for the MINUS side. My high power inverter attaches to the top of these two fuses. with 1 ft long cables.
I then took the three cables that originally attached at the battery plus, and the two white cables that attached to the battery minus, and moved them into the coach. They're now attach permanently to the bottom of the fuses, along with the #4 cables that go directly to the battery.
When I remove my coach battery for the winter, I have two small pieces of rubber hose that I slip over the #4 battery wire terminals so they won't short out while their flopping around inside the battery box compartment, and everything, including the cigarette plug, runs fine off the converter when I plug into shore power, or start the truck.
Hope this helps and answers your question.

thank you this explains alot

I'm a little confused about the lighter not sure where it fits into you question lights,lighter,heater,water pump all run off the coach battery. Your converter/charger has a relay inside of it and what happens when you plug it in it turns off the battery and runs the lights from the converter and at the same time it charges the battery in other words when you are plugged in the coach battery is out of the picture. So if the relay contacts stick (some what common) when you unplug it it can not switch back to battery power.
i mentioned the lighter because in the wiring diagram it looks like lighter runs off the aux. battery.wthe relay. thank youhy would it work with the aux battery removed as well as lights.the answer you gave sounds good i will check out the relay. thank you

i have posted about this before. 1979 dolphin. the lights in the cabin all work when plugged using the convertor. when i switch over to 12v they dont work.i looked at the wiring diagram from this site and this is what i have.i have 2 brand new batteries.but i ran the motor home on one and all the lights worked and cigarette lighter.i didnt have the cables hooked up at all.are the lights supossed to work like this.the diag. shows cigarette lighter is run off aux. battery?maybe previous owner has rigged up something.i am checking the wiring but want to know what you folks think about it. thanks
-
1979 dolphin. the striping around the cabin is quite faded.i would like to paint them, they are the brown and sort of orange color.also they are not smooth like a wood grain. any ideas? thanks
-
i have a 1979 dolphin here i denver colorado.great little unit. will post pics. soon
-
i know i read about this before. i was looking at some leaf spring helpers to give the rear of my 1979 dolphion a little lift. do these actually help?any recommendations. thanks

All the replies are good, but if it is litteraly a small spot on the driveway, it may simpliy be condensation coming out your tail pipe. Very comon in WI. winters. For every gallon of gas you use it creats 9 gallons of water, and if your exhaust is cold it will condesate in your exhaust and leak out. (this will not smoke) The black is from the water washing out your exhaust pipes. This also makes intersections and areas at our stop signs very slipery.
thank you for all the help.i will start with the easiest. i'm very glad i found this site.
-
i assume you mean the exhaust itself causes the spot, ie black smoke comes out. i remember being told that if it's black smoke it's probably some oil leaking into the cylinders and burning off when started. if you are using a little oil this could be it. white smoke was usually water vapor, could be caused from condensation while sitting or a leak from your cooling system into your combustion areas. if it's a coolant leak you should be adding coolant once in awhile. can't be too bad if it is still running ok and the smoke stops. one thing for sure is if you are using a little oil you know the oil pump is working
). if it under the rig where the spot shows up you probably have a hole in the tail pipe.the spot comes from the tailpipe out of the side. also uses no oil or do i have to add coolant.yes it runs great.it does get lousy gas mileage though.like 10 per gallon.

hello again. have 1979 toy dolphin with 20r engine.it has about 78k on it. when i start it up it will leave a black carbon looking spot in driveway. after 2-3 minutes it stops and no more driveway stains. any ideas. thank you d g

dolphinguy - what sort of place are you looking for? What is "too" expensive? How long are you thinking of staying?
I'm from Longmont and I know a few around there. Otherwise I can only really recommend places that would require a bit of offroading. There is also a Camping World on I-25 just north of the Highway 66 junction (barely north of Longmont, headed towards Loveland). Supplies and information can be had there.
hello i am in berthoud. i'm looking for a few places to stay a few nights. i just got the dolphin rolling and want to check some places out.either with or without hookups. thanks
-
looking for some reasonably priced camp grounds in the loveland/fort collins colorado area.what ive found is either way too expensive or do not allow older rvs in.i found two that were350 a month but denied me because of the age of camper. i have a 1979 dolphin.she is in great shape. so any info would be appreciated. thank you larry
-
i have a 1979 dolphin. the 12v lights and pump do not work.when i hook up to 120v every thing works fine.any information i find doesnt talk about the dolphin that i have. i have checked all fuses under dash and most wires i can find. is there a fuse that controls the 12v system when running on the battery? thanks larry
). if it under the rig where the spot shows up you probably have a hole in the tail pipe.
