I have a 1987 BJ74 w 13BT. Alternator is only putting out 22 VDC. Installed a new external Voltage regulator but did not change output. Any suggestions or source for an alternator? It has been suggested to replace the stock alternator with one from an Isuzu NPR diesel truck but the wiring is a mystery on that mod. Any help would be appreciated.
