thanks again!! just an update..(posted this in the other thread too..hope it helps someone)
thanks for this info..very helpful to me...although it wasn't my problem it was a great place to start!!!
just for some added info here..my van was doing the same thing ..had the same worn spot on the wire harness (beside the battery) but the wires themselves were fine...mine ended up being on the other side of the radiator..the rubber overflow pipe for the radiator was rubbing on the wire harness..made a pin hole in the wire casing and got wet then shorted out..spliced a new wire in and all good now

thank you again for the great help!!!
