I installed the specified alternator with my Coyote engine in my 33 hotrod. Engine runs great, the alternator, not so much. The Coyote instructions say to connect the yellow wire from the engine alternator harness to IG pin on the alternator as well as the power cable back to the power distribution post. All that done and still no juice from the alternator (12.2 volts off, 12.05 running). I suppose the alternator could be bad but it is a rebuilt and tested unit from Autozone. Any ideas, did I wire it wrong? Any help much appreciated as always!!!
