Jim,



What is the voltage from the alternator frame to the + post on the
alternator?

I am having a problem with my Leece-Neville alternator overcharging. I
had it rebuilt as preventive maint.,it woked ok for about 800-1000
miles then it started over charging 15-15.5 volts & 80-100amps. I took
it back to the rebuilder and they said the regulator was bad so they
replaced it. They told me to check the voltage to the small + post
under the regulator. I was getting about .75 of a volt less than
battery voltage as measured at the big + post. I could not find where
the volt drop was so I ran a new wire from the ignition operated
solinoid above the throttle pedal. The alternator is still
overcharging. We are supposed to leave on Friday for a 4000 mile trip
so this is a big problem. Did Bluebird use a special regulator since
they have Batt. power to the alternator all of the time? The rebuilder
may have installed the wrong regulator. Thanks Jim Matus 84FC35 Rescue
