Hey guys I have a question I recently did some work on my car(simple engine bay paint job) so long story short when I had plugged and connected all grounds & tried connecting my battery back on the positive post it would just constantly spark. There was some thing I did mess with before all of that the if I’m not mistaken it’s the TW sensor(on the head) the wires had detached from the plastic plug and wasn’t sure which side went where could that be a reason it burned the ground on my starter? NEED HELP,ADVICE,TIPS
