8V92 alternator questions

Previous discussion on this or the other Wanderlodge forum was that there
might be a bad ground to ALT #1. I have the same problem but my 93 PT is in
Florida until Friday when I go to retrieve it. I'm going to pull the floor
when I get home. I had the Alt. rebuilt last summer when it was pulled just
as a preventive maintenance issue, still read no voltage when replaced but
didn't have time last summer to tackle the problem.

Subject: [WanderlodgeForum] 8V92 alternator questions



I've got a few questions after I describe what I'm seeing on my
dual-alternator 8V92:

After starting, the voltage is somewhat below 13, and alt2 is running about
50 amps. Alt1 is essentially zero, although there is a slight upward blip
when changing the display from alt2 to both.

Voltage slowly rises, and after quite a distance (100 miles or more) the
voltage is in the 13.5 range. At around that time, the Fault light comes on.
Alt2 at this point is running around 25 amps, and there is no apparent
increase in the both position.

What do other 8V92 dual-alternator owners see for charge rates, 1, 2, and
both? I'm presuming the zero/near zero is telling me I have a bad
alternator, but is the 50 amps from Alt2 also low? If it is, what does that
mean?

Does anyone know, on theirs, which alternator is 1 and which is 2? Front
top, or back by the bumper?
