Got a new Truck (new to me)
OK, have been wrestling with charging issue over the last so many weeks.
Guess it was time to get educated in "Charging System School".
On board '89 Truck computer contains the Voltage Regulator that failed.
Went to experimenting with external voltage regulators and different alternators as all tests had large overcharging issues, like 30 volts overcharge.
Apparently there are wiring issues of backfeeding with the original computerized truck wiring, that is now being bypassed.
Glad I wired in an inline fuse that was heading back to the battery.
The ultimate fix was wiring in a 3 wire Alternator and using the aftermarket 1 wire conversion kit. So that the Alternator and Regulator are now self contained.
Now holding 14.32 charging volts.
Success, now to straighten up the rest of the wiring on the truck.
