Welcome, I am Chris (aka-Moose)

Is there anything else powered that should not be with the key off?

Can you do electrical diag with a volt meter or test light?

As mentioned in my first response, I would stay in contact with you. I've noticed you have not rated the post. So I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.
