seems. The alternators to not have have a common ground but the battery bank
does. The alternators use shunts to meter with and you may actually be charging
but your metering may be bad. Go on Ebay or Grainger and purchase a DC clamp on
ammeter and drain the batteries a bit and high idle the rig and measure
everything and compare it to all the metering plus use a good quality DC
Voltmeter. Don't get fooled in to thinking you have a problem until you verify
with alternative metering that you really have a problem and not just a metering
error.

started it there was no alternator charge, usually there is about a two second
delay from start to charge showing on the gauge. On the trip I hit a bump and
there was charge for about 30 seconds then none. Both alternators are new as of
three years and about 20,000 miles. To me it sounds like a ground problem.
Also I ran the generator and the coach charge came up to about 10 amps
