Hello All, new to this site hoping to get a little help. I have a 2002 Air Nautique with PCM 305 Chevy. The ECM was fried, sent it out for repair and put back in. Started right away and ran good until we put it in gear then shut off. Sent ECM back for repair was told it was fried again due to "power surge" or "short." Tried going through the basics to find a short with no luck. I now have a good repaired ECM but can't find the power surge or short. Any suggestions. Thanks
