Hi all
Brand new 120A alt from Rock Auto. The power and ground feeds check out, but there is no voltage at the field wires. System voltage with the car running is 12.xx until the battery runs down. I had it down to 11.87 and the car was still running with no noticeable problems. Oops.
Tonight was supposed to be the night I broke the engine in properly, but then this came up.
Assuming no broken wires or unplugged connectors, what are the possible causes and solutions to this problem? Also, the check engine light is on but the only codes it throws are 12 and 55.
