  1. If it ends up being a bad sending unit you might look at the link below. They rebuild fuel sending units. I believe most of the Toyota motor home fuel tanks were installed by the RV Converter (Dolphin, Sunrader, etc) and may use a sending unit which would likely be unavailable. I know nothing about this company, just had it saved in my links should I ever need it. There are probably a few others that do this as well.

    We checked further and seems like it's a bad sending unit... and the tank is an original Toyota tank so... do you know some place online where I can order a sending unit?

    Thanks!

  2. I checked the wires at the tank and found out that the gauge goes full when I ground it... when it gets a little warmer outside I'll go to my friend's place and we will check out at the tank to see what's wrong. Thanks everyone!

  3. hehe you are right about 20+! ;)

    I tried what you said, I found the connector, I unhooked it and checked with my test light... unfortunatly, I get no signals on both wires. There is a blue and a white wire there. I followed it and it goes in the cab through a hole. I don't know where it's going then. Wire under the truck looks fine and OK. I'm sure the problem is not the outside wire. Do you know what I can look at after this??

  4. Hi! This morning I started my 1989 Odyssey and everything was fine so I took it on the road for a ride. When I got on the Highway, I noticed that my gas gauge wasn't working anymore... it was 15 minutes before.

    Can I do something easy about this?? I never had this problem before. Thanks!

  5. Hi everyone!

    Today I found out that my coach battery isn't charging... I replaced my battery isolator this summer and I thought the problem was solved. But it's not!

    The problem is weird. I made some drawing to explain it to you. What is weird is that when I'm plugged into AC power, I get 14V to the isolator at the side of the coach battery. But when the engine is running, I get 14V too, but it doesn't get through to the battery... I don't understand why when plugged into outlet the 14V would get to the isolator, but when I'm using the engine, the 14V won't get to the coach battery....

    It's only working one side. Can anyone tell me what I should looking for??

    Thanks!!

  6. I moved the wire for the charger from my main breaker to another breaker that i cut off and plug my rv into my invertor. I just turn that breaker back on when i plug into land power and turn it off when i plug into my invertor. It works great. i been doing this for about 6 months now.

    Good idea, but what if you forget to turn it off?

  7. No because the charger/converter will try to run you can't take power from the battery and try to put it back in at the same time with the charger, when you plug in the cord to the inverter the charger/converter in the motor home will run like it or not. If you could/can turn the charger/converter off your ideal would work just fine. If you know some one clever with electrical work convince him (a beer or two might help) to add an outlet for you just for the inverter. You can run a 600 watt microwave with the inverter but remember it will draw a lot of power from your battery so use it sparingly.

    Ok good, that's what I wanted to know... I'll look what I can do, my Micro Wave is on top of my fridge so it's hard to run a cable there... On the fridge, there is a 12v outlet and it's told I can use it for TV only, I guess the 1000W inverter would take too much power if I plugged it there?

    Thanks for your answer.

    By the way, I want to use the MicroWave oven for baby food while on the go.... I'll use it like 30 seconds at a time when we are on the road. So I think my battery can handle this and more...

  8. Yes, there is no such thing as a free lunch your charger will try to run and it's not very efficient so you will end up with diminishing results. Most of the charger set ups go right to the main breaker so you can't turn off the charger too bad because without it, it probably work fine.

    So you mean I can plug it that way no problem or I can't? Will I be able to use my 700W Micro-Wave Oven?

  9. Is it possible to wire a power inverter this way?

    I'd like to plug it on my coach battery and plug the 110v power cord in it so I would get 110V everywhere in my RV. I want to know if there is a problem with the charging system that will send 12v back into the battery so the inverter...

    Thanks!

  10. OK that's a solid state one. So what you need to do is check the voltage (truck running) at the terminals of the isolator that have the bigger wires attached. One goes to the truck battery and the other to the coach. In the middle is the alternator wire (marked "A") if you have the same voltage at both of the battery terminals the isolator is fine. If one is lower the isolator is toes up. If you check the alternator voltage is will be more by about .7 volts that's OK. If the output is fine you need to have a look at all of your connections most likely there is a breaker in line in the wiring some times they go bad if you have voltage on one side and not the other it's bad. Beyond that is just a matter of looking at all of the connections and wiring clean every thing up and see what happens.

    Ok yeah, I don't have the same voltage on both sides... I have like 14v on the engine battery side and 12.50V on the coach battery side... I even disconnected the coach battery and I was getting 11v when engine was running... I guess it's toes up. I'll go buy a new one and try it.

    By the way, is it ok if I plug 2 batteries on the coach side?

    I bought a second one and I want to connect both to my motorhome.

  11. What kind of voltage at the truck battery? Do you have the isolator that looks like a starter relay or one with cooling fins?

    I get 14v at the car battery when engine is running. I think it's the one with cooling fins, it's blue with 4 bolts on it.

  12. Check the voltage at each battery while the engine is running should be about 13.2 - 14.2 volts.

    Ok, cause I just checked it and I don't get more than 12.50 at the coach battery... I disconnected the coach battery completly and when the engine is running, I get like 12v at the coach battery connection... you think my isolator is broken?
