Guest Posted March 19, 2010 Report Share Posted March 19, 2010 the only reason i can think of that its arching is because its not fully contacting (touching) the alt stud. Quote Link to comment Share on other sites More sharing options...

Colin - STAPUFT Posted March 19, 2010 Report Share Posted March 19, 2010 the only reason i can think of that its arching is because its not fully contacting (touching) the alt stud. Yep, or touching the stud and the case of the alt (direct ground). Could you have over torqued something on your alt stud? If so and the isolator between the alt stud and the alt case is compromised, then you will have a direct short.

tyhead Posted March 20, 2010 Author Report Share Posted March 20, 2010 any word yet of what happened? Yeah, the wire was touching the case. I've had it off the battery since then, but I'm going to do it right today. Quote Link to comment Share on other sites More sharing options...
