earlier today I was driving around in my car no probs, then went to get lunch and about 2 hours after that was going to go to work and the car wouldnt turn over, no power or anything, when I got back from work 4 hours later the car started up, drove it to my garage, shut it off, and wouldnt start again, I checked to see if I was getting any kind of shorting problems, so I took off the pos wire and ran an ohm meter to ground and it zeroed out, I took the starter off to see if the batt wire had fried or something and that wasnt it, I tested each of the main wires with the fuse links in them and one of those is reading 0 ohms when ran to ground, its the ring terminal that has the 2 wires coming off it, then each wire has a fuse link and one of those splits off into 2, I cut the wire to see if one side or the other was the culprit, but they both independently still read 0 ohms, does this sound right? I would think that with the key off and everything out that there would be no power loss to ground anywhere off the pos wires from the battery. any help would be appreciated
Thanks

I think this is more of a starter solinoid problem, the next time this happens (when you turn the key and get nothing) try to jump the the starter, ie. the screwdriver trick. If it cranks over, then its your solinoid thats bad. Of course the key has to be "ON" for the car to start up. Or you could have it tested a Parts Store.

As for the 0 OHMs reading on the wires, to test a wire for a short, both ends have to be disconected from everything. If you were testing just one end of a wire, not knowing where the other end of the wire was, then you would more than likely get a 0 OHMs reading. This is because eventually a circuit will ground out, thus the reading 0 OHMs.

Hope this helps. Let us know.
