1995 240SX non-se

Earlier tonight about 9pm, I started the car. About 1 minute later, it just died on me, just turned itself off. It did not gradually stop, it just stopped. I tried starting again but no luck. No sounds, clicking or anything. The dome lights and headlights were working and no dimming. So the battery wasn't an issue. I was thinking bad alternator? If it was alternator, the battery should have still kept the engine going right? Also, it could be the starter not making it start, but battery lights should come on anyways.

Ok, In conclusion I found out that the ignition relay in the fuse box had blown out. So I used the RAD FAN relay (they were both 30A). I turned the ignition on and I saw the battery lights go on for less than a second then went out. The relay blew again.

My question.. What can make the relay blow out? Obviously > 30A, but what can cause it to get more than 30A?

I was just looking at my power schematics. Could it be my battery giving too much current? I just bought a $10 multimeter at WalMart and the thing doesn't work.

Ok, with a new fuse, I put the ignition on the ON position to see if there is a short in the starter circuit somewhere. The fuse still blew out.

What is the similarity between the connections in the ignition relay 1, ignition relay 2, and the start,theft circuit to cause more current flow (short)??????????

sounds like you have a bare wire hanging somewhere.

finally fixed it.. ignition wire on the harness (blk/red) was touching one of the fuel injector screws and it melted it partially to where it shorted..
