I'm leaving on a long trip in 3 days, and trying to work the bugs out of my 1983 ( Chevy 350 ) Class C. I'm seeing normal reading on the battery state gauge and the dash volt meter with the engine off - 13V on both. When running, both meters show just over 15 V, the edge of the red zone on both. Also, I have occasional alternator belt squeal on the roadl, and the belt is tight and new(ish). So, the alternator seems to be working very hard for some reason. I have the coach battery switch off ( coach battery shouldn't be affecting, if I understand the function of that switch.) Also, meters and belt squeal behave the same with that switch in the 'dual' position. I have the charger on the engine battery, and it's drawing about 2.5 amp, 3 with some accesories running. So, that battery seems normal to me.
Do I have a bad regulator ? And, if you think that's the culprit, is it going to be built in to the alternator on an '83 Chevy 350 ?
I appreciate any insights. I've got a few days to de-bug, and then this puppie's on the road . . .
Update - I topped off the engine battery with my garage charger until it was reading just 1 amp draw, and vehicle still indicates 15+ volts when running.
Local auto parts stocks 78 amp alternators for this engine - I can't find anything in the paperwork with the MH that indicates what amperage the stock unit is. I also came across the warning not to start the genny with the battery switch in 'dual' due to possible alt damage. . . wondering if this is what happened. The voltmeter was high on the test drive before I bought, but I figured it was just a low battery from sitting. . . . .
