The diode is located in your battery charger compartment, under the shelf where the battery charger(s) are located. You should replace it with one of these-

This device will allow your chargers and/or alternator to provide more voltage to the generator battery and will close when you shut down the engine or turn off the generator- allowing your charger(s) to act like an alternator for the generator.

Here is a photo of my 1985 PT40 charger compartment. In the upper center of the picture, you will see the predecessor to the ACR (Automatic Charging Relay) which I posted in the link above. I have installed 4 of the ACR's on various mid-80's coaches and we solved the problem you are experiencing in each case.

And you say your not an Electrician and have never played one on TV.
