P0622 DODGE -

Question

I touched the coil pack and got electrocuted and then I started having problems with a lot of engine codes, I had a battery light come on and a few codes, I changed the alternator and the battery and I have gotten another code, p0622, I don't understand what could be the problem. also I took a voltmeter to the wiring of the alternator while everything was plugged in and it showed a11.5v to it, I figured it was an alternator so I replaced it because the wires seemed like they were getting voltage please help I need it to get to work

Answer 1

P0622 Generator field control circuit

The charging system is controlled by the PCM which grounds the alternator field, With key on engine off the field grounds should measure battery voltage, With key on engine running the field should have ground (or on and off), For now check the connection at the starter you may have a fuseable there going from starter to alternator show check that,

Comments

if the fusible link is bad, do I have to replace the whole harness wire or just the fusible link? if that isn't the problem what else could it be? thank you

Test battery, then test alternator (B+) at the alternator is should show battery voltage, You do not replace the whole harness, if the fuseable link is open, The fuse should be located in the power fuse and relay box. You may have to test the field circuit,by grounding the field with car running and measure voltage, if it charges you will need a PCM, and it will need to be reprogramed
