In other words, if you can read the electrical diagrams then you can track down the short. If you can't, then you can't be sure that a particular line is acting incorrectly. With so many controls routing through the black box, I find that none of the lines ring out the way they normally would. There's a certain amount of minor flow through the system at all times to support the SID and computer. Perhaps your mechanic found this an mistook it for a short. You have to be careful to measure how much flow there is, not just the flow. (If your mechanic is a Saab mechanic, he might know this). How old was your battery ? Bob
