My supra finally left me stranded after almost 6 months of driveing with no problems at all. The Problem Im haveing is that it is getting absolutly no power at all anywere. The battery is fine so I know thats not it. I looked at all the fuses under the hood and all the relays and everything checked out fine (that I could see and tell), next I took apart the fuse block to look for loose or damaged wires and didnt see any. Now I can take a Piece of wire and jump it from the positive on the battery to the alternator and everything works just fine (how I got it home) it cranks right up, drive and runs like absolutly nothing is wrong. Dont even throw a CEL, Im pretty good with working on cars and know my way around pretty good, except when it comes to the electronic part of them. I have a voltmeter I just wasnt sure were to start testing or even really were to set the voltmeter at (what volts and stuff to set it to) to get the right readings. If anyone can help it would make me very happy. Cause until it gets running like its suppose to I stuck driveing the ol ladys camry lol.
