I've been chasing down this electrical draw for over a week now. I'm drawing between .48 and .51 amps with everything off. I know it's in the IGN circuit because if I pull the 30A IGN Fuse under the hood it goes to 0A. Now I know it's supposed to pull a little through there, but general consensus is that no more than .08-.1A or so.

I have 2 AEM Gauges in the car, a sound system, a turbo timer and that's about it for wired electronics. I disconnected the radio, the turbo timer, the entire instrument cluster, un-plugged all the steering column/ign bulls**t still get the .48A or so. Pulled every interior fuse, ECM, MFI Relay, all under hood and interior relays, dimmer switch etc. /ubbthreads/images/graemlins/banghead.gif

So, can anyone in here help me to figure out where the circuit leads from that under hood fuse? Have any tips/suggestions? Having a dead battery after the car sits for 2-3 days is getting annoying! Thanks!
 

I assume you are referring to sub fusible link #5 in the relay box?



The manual says that it feeds the alternator S terminal, and the ignition switch. With the ignition OFF the alternator should be the only thing in the circuit, from what I see. Try unplugging it.

Jeff, You are exactly right! I wasn't reading the diagram right. I disconnected the plug at the alternator and it dropped to 0A. Now my next dilemma... I was reading and learned that sometimes the diodes can stay on in the alternator. Do you think it's an alternator problem, or a harness problem? I do have a Saturn Alternator, and did the wiring the way numerous others have suggested.

Thanks a ton Jeff, now I at least have a single circuit or component at fault.

It actually wasn't the alternator. I figured it was as well. There was a bad wire connection about 6" after the alternator plug. I re-did my GM plug, and found it a couple inches past that where it looks to have been previously repaired. Thanks Jeff.
