QuestionAfter work car dead, checked battery measured zip, disconnected cables, battery voltage rose near 10V, back to about 0v when reconnected, tried jump, lights flashed horn beeped (security), read manual and pushed "unlock door" w/ keyless remote to stop beeping, seemed to almost start but would not, friend indicated a lot of current being pulled, disconnected battery and measured resistance btw cables ...near dead short (~1.5 ohms), night before I replaced Vehiclr Speed Sensor and disconnected bat to clear code, drove ~45 miles to work no problem next morn, coinsidence or something in computer? assume that pos of bat goes to soliniod (appears OK as almost able to start car) obviously something shunting great deal of current away from starter?? Thinking I can discon bat - pull a fuse - reconn ect... till I find what circuit is pulling current...hoping someone might have had similar experience and have an idea what issue might be. No mods made to car (radio ect..) has 130K miles. Any ideas?
AnswerHi Mark,
I would work backwards here. Disconnect VSS first. Should not be giving you this problem, but it was what you changed before all this happened.
You are doing the right thing by pulling a fuse at a time. Don't forget about the auxillary fuse box (should be in trunk on pass side.
If you really suspect the starter, hit the case (not nose cone) with hammer. I have run across starters that have drawn excessive amperage because of internal failure although this is commonly after engine has warmed up and a restart is applied.
I do not believe that you have a computer problem that would cause this type of event.
I am thinking something that has constant power that has failed electrically like a power seat etc.
If you have no luck isolating with pulling fuses, go to the relays.
Power seat, retained power,windows etc. all run off of relays.
I would be real interested to find out what you come up with. Please let me know.
Rob
