You need to check the voltage at the alternator and at the sense wire for
the regulator. A bad connector between the two can cause the alternator to
generate an over voltage condition so that after the voltage drop in the
connector between the alternator and the regulator, the regulator sees a
correct nominal voltage, everything else sees a high voltage. Check you
connectors, crimps, ...

Subject: [LML] Overvoltage replies

Thanks guys for the replies.  I have replaced the alternator and
still have the same problem.  I checked my connections in the voltage
regulator and it has been replaced recently also.  The only "old"
thing left in the system is the overvoltage, and I don't know of it's
screwed up and kicking in when it's not supposed it.  It's a
prestolite regulator of the types they use on Cessnas (I am
assuming).  It's a PMA'd etc part.  I'll try not to fry anything.
