how do you check for electrical draw

???

[majorownage]

voltage and amperage

To see of you have one?

Check battery voltage with leads off, hook leads up and check for a variance.

There will always be a draw because of the ECM and radio. But there is a certain amount of miliamp draw that is no bueno. I think anything over 30 or 40 milliamps is bad.

How do you find where it's at?

Simple, pull fuses until the draw goes away.

Locate said fused circuit, find the problem and fix it.

start disconnecting things

So disconnect the battery and check the voltage of the battery. Then connect the battery and recheck it and see if there is a difference greater than 30 or 40 milliamps? In other words check the battery's voltage hooked up and disconnect and compare the readings?
Assuming I understood this correctly and this is all done with everything off,
Next, if I find I have a draw, then pull one fuse at a time and go check voltage at the battery with it now hooked up to see if it changed significantly?

i just went through this and mine turned out to be the connector to the alternator that doesn't go to the battery...i assume it goes to the computer

Voltage will give a very vague readback.

Get a multimeter and bring it down to milliamps.

Amp = current/power
Voltage = pressure or speed.

disconnect the negative cable, put a test light between the post and cable...does it light up?

Headin home now I'll let you know in about 10 min

x2 and once you do that and you get the light to come on then start pulling fuses to see what circuit your issue is on...

[Blackpony]

disconnect the negative battery cable, hook a volt meter inline and see how many volts are being used..

[TEAMJACOB]

It does light up...

[Blackpony]

need a volt meter to tell the difference in surface volts and draw volts.

[greenbullitt]

start pulling fuses till it goes out, then youve found the circuit to investigate

[TEAMJACOB]

Ok when I pull one specif fuse intstead of a bright light it is noticeably dimmer and then fades to the slightest glow. Doesn't do this with any other fuses.
