Posted October 29, 20195 yr comment_586588 While doing some relay troubleshooting, I accidentally sent 12v through W34 (the ground wire on the air regulator) I saw sparks for a split second a pulled the wire off. This wire is a ground going up to terminal 34 on the ecu. How much damage did I just do??!
