1982 PT-40 (generator battery not getting charged)

[Kevin Ford]

Hello:

After owning my '82 PT-40 for 8 years I have just discovered this BB
forum and as you all know the knowledge for keeping one of these old
birds flying is priceless (thanks). So, here is the issue I have
today:
The battery on my generator is not getting charged. In
troubleshooting yesterday I disconnected the all of the generator
battery cables and I'm getting 12.7V from the coach cable providing
voltage until I reconnect the dash voltmeter, then the voltage pulls
down to about 5V. The in-dash volt meter does work, so I don't really
expect it to be the issue. I therefore assume the problem is load-
related or a cable connection problem from the coach charging source
(s). I tried to follow the charging source cable, but could not find
where it connects on the coach. Can someone tell me where this cable
connects into the charging system or if you have any other insight
that would also be very much appreciated?

Thanks!
