I was doing some more voltage & resistance checks, this time with the seat(hood) up. Some test with the engine running. When I turned off the engine, I noticed the fan would spin a few revolutions, but the alternator belt would stop. I pushed down on the alternator belt and it was so loose I could push it down at least 1.5". I tightened up the belt and now I get 13.5V when running! Apparently the belt was never tightened and it was slipping. Now when I turn off the engine there is a chirp from the belt trying to slip on the fan pulley, but that's a minor annoyance to have a working alternator. Maybe time for a new belt as when the alternator was changed, they kept the old belt on.

As a side note, there is not idiot light, no lights at all, on this forklift. It would be nice to have a wiring diagram for future us, if anyone has one.

Thank you PRAUTO
