battery drain / glow plug relay
hey guys, i am on vacation with my family and my early 99 ps 6spd dually is draining the batteries. got dark on me tonight before i got it tracked down but i noticed when i put the positive battery cables on the batteries there is an arc. i dont mean a spark, i am talking about it looks as if the cable is gonna weld to the terminal. i pulled the altrnator wires, starter, ect then pulled th wsire off the starter relay and killed the arc. that wire goes to the glow plug relay. i then hookd it back up and pulled the brown and yellow? wires off the relay and tried again and the arc stopped. it got dark before i got any further. are those brown and yellow wires feeds for the glow plugs? i did pull the injector harness's off the vc gaskets one at a time but the arc was still there. this is all with the key off. any ideas on what could be causing this? short in one of those two wires? gpr stuck on? i am assuming this arc has something to do with my battery drain. i apreciate your replies!
