95 yj 2.5l manual trans - Recently swapped in a VW 1.9 TDI ALH engine with standalone ECU and harness. Starts and drives good. Need to connect the Jeep alternator exciter wire into the new standalone wire harness to get the alternator to charge. 2 wires that went to the jeep alternator: dark green (Field Generator Driver wire) and dark green with orange stripe (Field Generator Source wire). Assuming the dark green wire (no stripe) is the exciter wire? When i turn on the key or start the engine hoped to see 5 volts from the dark green wire. Neither wire outputting any volts? Getting 12.4 volts at the battery and 12.3 volts at alternator. Hoping someone on the forum can help me out. Newbie, never pulled or swapped an engine. Owned my Jeep since 95 and always done all the maintenance and parts replacement. Thank you!
