I have attached whatever diagrams I could find on the fuses and relay boxes and guides to help you test them

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

My son has a 92 toyota corolla and there appears to be something shorted and draining his battery. I initially thought that this would be easy to find and was proven wrong. With the car turned off, I put a current meter in series with the battery and found that there was imitially 700 mA of current being drawn with everything turned off. I proceeded to remove every fuse in the fusebox one by one and was expecting to see the current disappear when I came across the faulty circuit. I removed every fuse one at a time while checking the current draw and found the current still there. I also removed all fuses in the 2 fuse boxes next to the battery to no avail. There is a bank of threee square fuse looking things right at the positive cable that I could not remove. Any ideas as to how I can properly troubleshoot this. The current was drawing a little over 1 amp after I finished removing all fuses. Finding the source of 1 amp should be easier to find than I am expecting! Please help!

Thanks.
Carlos

Those little squared looking things are the fusible links-

Now did you remove all the fuses in the fuse block-if so disconnect the alternator-is the draw still there?Get back to me

Removed every fuse 1 by 1. I will do that this evening when I get back from work. Could be the diodes in the alternaotr going bad right?

Thanks again,

Carlos

A break in the rain here in the Bay Area! I went out this morning and found that it is not the alternator

The battery was disconnected from the negative post since the last check (few days).

The only thing that I opened was the hood (doors closed) and hooked up the meter in series with the negative post. This time the current draw was 4.1 amps. Last check it was 1 amp! I proceeded to disconnect the alt (2 places) and the current draw remained the same. After about 5 minutes, the current started to get lower and stabilized at 2 amps. I opened the door and this time removed all the fuses and the current remained the same at 2 amps. Out of curiosity I turned on the lights and the current draw went to 9 amps.

Any other suggestions?

Thanks,
Carlos

Out of curiosity I turned on the lights and the current draw went to 9 amps. Of course its gonna be higher-your loading it.

Disconnect it again and this time put a test light in between-and restart removing the fuses.

Amperage draw allowable is only 0.30 milliamps. Set the amp scale in millamps.

The current draw was initially 4 amps and it dropped to 2 amps. This is with all the fuses OUT of the box.

I am using a Fluke 8010A Multimeter

This has 2 modes (scales)

Scale 1 is the 2000 mA (2 AMP) Scale and this has a fuse.

Scale 2 is the 10000mA (10 AMP) Scale with no fuse.

This morning I put the meter on the 2 AMP scale since I previously measured 1 amp (1000 mA) and it blew my 2 AMP fuse. I realized it was drawing higher so I put the leads on the 10 AMP scale and that is where I get the 4 amps from.

Again, this is with all the fuses removed and still out of the box.

Ok, I removed the fuseable link from the battery and of course the current draw went to zero. I then removed the nut holding the wire to the blue FL. I then touched the wire to the post and the current draw is in the mA's
I then removed the nut going to the pink FL and the middle came tords me. I touched the main wire (Black with a red stripe and the current draw is 2 amps. This black wire the red stripe is what is leading to the short. Any idea as to where this wire goes? Is there a wiring diagram on line that I can get it from?

Your inputs are greatly appreciated.

Black with a red stripe and the current draw is 2 amps. Is this the wire with the 100amp fuse. If so disconnect/remove all the wires from the alternator and see what happens.

I traced this wire to the back of the engine going to the bottom. As I traced the wire down I noticed that the current draw came down to less than 150 mA!1
I couls feel that the wire was bare at the end and was shorting to something. I felt around and moved it away from everything and slopped some silicon RTV around the bare wire. I will wait till the weekend to lift the car up and see exactly what was shorting. In the meantime, everything looks normal now!

Thanks again for your inputs,

Carlos
