clifton maggard Posted January 1 Posted January 1 These forums have been very helpful. I have a 1980 Toyota Dolphin RV series 500 . In the area where they have the electrical it has a 30 amp breaker and a 15 breaker. Does this make sense, for the wire that's connected to the air conditioner is a 12/3, thus 20AMP Max wire. Shouldn't that be a 20 amp breaker. Also what should the shore power be 120 volts 20 amp or 120 volts 15 amp STOCK. Trying to set it up like it was stock from the factory. Also does anyone have an electrical diagram, for it has been modified horribly. Thanks CMaggard Quote
WME Posted January 1 Posted January 1 See if you can find the sticker for the A/C. Normally the 15 amp powers everything in the RV, except the A/C. My current rig has two 20 amp breakers, one for for each A/C A little foggy memory but I seem to remember a 3rd breaker in my Toy (10-15 Amp) for the microwave Quote
clifton maggard Posted January 1 Author Posted January 1 Thank you. I did find that sticker, but it was too faded read. I did find this 1979 Dolphin Owners manual below, which might be similar. 1979 Dolphin Owners Manual.pdf Quote
clifton maggard Posted January 2 Author Posted January 2 Yes. FyI this is not my vehicle it is my sons. From the information from this WebSite we have also determined that my son needed to have dually axle installed, which has been done. Thanks Quote
extech Posted January 3 Posted January 3 ac/heater for sure,although prob not available in 1980 Quote

At first I though this diagram for fridge only too, until I saw the HEATER label. This was located under a access panel on the outside of the motorhome on the backside of the fridge. Quote

This was located under a access panel on the outside of the motorhome on the backside of the fridge. Fridges have heaters. That's how an absorption fridge works, heat from propane flame or heat from an electric heater The fact that the diagram has 115v AC and 12v DC heaters is what triggered the comment. 12v DC heat would be VERY inefficient in a house heater.

extech Posted January 3 Posted January 3 the text that was with the diagram said the heater is only to take the chill off Quote

You will notice the heater is labeled Heat Package and it shows it plugs in. The heater package was/is optional ($75) for most of the RV A/Cs, they are around 5K btu. Most Toy AC are 13.5 K btu, so 5K btu ain't for much but to keep the chill off. Don't forget the racket the fan makes. Quote

Didn't think about that very interesting . I see what your talking about now. I have never owned an RV. I'm working on my son's RV. Thank you very much ! Quote
