1986 Minnie Winnie Generator won't crank

[lostone1413]

I have a 1986 Minne Winnie. The Generator will only start if the RV is running and I'm using the dual battery switch. When I try and start it without using the battery switch allot of times the generator won't even click. I replaced the batteries. Both of them. They both read 12.7 volts. More then enough to start the generator. Other issues that started with the generator not starting are. If you start the generator using the dual switch everything works fine with the 120 and 12 volts inside the motor home. When you unplug the motor home from the house and haven't started the generator you don't have 12 volts going to the motor home. At time when I start the generator with the dual switch on and everything is running when I shut off the motor home off sometimes but not all the time the generator just dies. I've had three people in the business look at it. None have figured out what is wrong with the motor home . What I was told was it was a transfer switch for the Generator. I was also told that in 86 they didn't have a transfer switch for the generator. I have to manually plug and unplug the power cord. Then I was told it could be the inverter. I was then told that the inverter has nothing to do with it. To me I feel all the issues are tied together. If I get the generator to start maybe everything else will work fine. Do you think it is one issue with the generator and the lights? If so you have any idea at to what could cause all this ??

Generally speaking when you have no 12 power it is the batteries. Either dead, shorting out, not grounding, or not getting power to where it is needed.
