Chris Posted March 12, 2007 Report Share Posted March 12, 2007 Also, i'd replace the battery, it sounds as though it may be getting old, but definately not puttin out the necessary power. BTW, How is Athens these days?

lovellsz Posted March 12, 2007 Report Share Posted March 12, 2007 someone will correct me if i am wrong but it is the 3 main wires with your electrical system, Battery to GND Battery B+ to alternator Engine GND to chassis.

AP Zoutes Posted March 12, 2007 Report Share Posted March 12, 2007 (edited) ^^^^ exactly right. Understand you are not replacing factory cable just adding to. Use 0/1 guage and you can get full juice from alternator and it reinforces your ground. Here are pics of the big three done in a Jetta. You have to scroll down the page a little, but it's there. http://www.stevemeadedesigns.com/board/ind...c=180&st=40 Edited March 12, 2007 by AP Zoutes Quote Link to comment Share on other sites More sharing options...
