No amps reading on #2 alternator
Today we checked out further the output of a re-built alternator on my
92WB. Found out it is putting out just fine, but not indicating at the ampmeter on dash. We determined that the instrument was O.K.. George at BB indicated problem could be circuit breaker or Bosch Relay. No problem with circuite breakers, but unable to tell which Bosch Relay is involved. There are 6 in a row in the battery compartment and all are wired the same and with color codes that are identical. Short of trial and error replacement, anyone have any experience with the problem or know which relay it is? Thanks, R.E. (Ron) Marabito, Moderator |

Ron there should be nothing between your alternator and the amp meter other
then the shunt. When the current from the alternator passes thru the shunt it produces a very low voltage drop across it proportional to the current and its this voltage that is read by your dash amp meter. I suspect you may have a wire off at the shunt or a bad connection(wire) between the chassis and the dash. What year is your coach?

Tom: I have a 92WB40. According to George in service at BB, when
the wire comes off the shunt, it is routed through a circuit breaker and relay on this coach. Alternator #1 shows up just fine, but not Alternator #2. I believe the dash switch probably controls the relay switching between the two alternators. I have not check the switch, and I guess that could be possible, but when we switched output wires from the alternators and I got a good reading then for #2 which was actually #1. R.E.

Ron I am not familiar with the dual alternator setup on the PTs. But I am
willing to learn . Cant figure out why they would want to run the wire thru a circuit breaker and/or a switch after the shunt? Doesnt the output of both alternators go thru the same shunt?

I have dual alternators on my coach. don't know why- but willing to learn,
also. Ernie 83PT40 in Texas [Non-text portions of this message have been removed] |

It appears to be two separate shunts.

I don't think it was an option until '88 Ernie (not sure on the year).
