Jeff,

While checking for a draw, remove one fuse at a time until the draw stops. Then you will know what circuit it is coming from. The mechanic that said is from a circuit labeled electric is as vague as one can get. That is like saying there is a drop of water in your pool that is bad, but I'm not sure which one. Try what I said and let me know what you find.

you will need a volt meter to read the draw on the battery.remove the neg. cable and hook the meter from the battery to the cable.read the draw.then remove the interior light fuse so you can work with the doors open.then remove all the fuses 1 at a time untill you see the meter drop to under 50 milliamps or under that.that fuse is where the draw is at.if these people dont know how to trace a draw find a new shop.

the fuse marked elec is where the draw is, one thing the mechanic showed me is that power is feeding back thru alternator with it plugged in, noise is heard in alternator , unplug alternator noise goes away, replaced alternator same thing happened, current probe showed .04 draw on that circuit, mechanic also said he cleaned all grounds. how do i check to find if trans solinoid is drawing battery down? mechanic also showed me with test light between negative cable and battery the test light went out when elec fuse was pulled, im gonna try replacing ecm tommorow, il have to pull elec fuse every time i shut off car, otherwise battery is going to keep dwawing down, i also had a recent problem with the cruise malfunctioning it accellerated by its self. jeff

opefully within the next 7 days i will be able to order a light pen,and rs232cable for 4 gas unit.

my new machine is a allen sea. parts will be coming from california

i obtained the allen smart engine analyzer for free.

i am excited to get the allen going it also came with a separate scope unit, and 4 gas analyzer.

this machine has far more features than my main engine analyzer a sun mea 1500.

which is currently down , a couple mice had a party inside last winter...

the sun will be running very soon, ive fixed 95 percent of the damage they did to machine.

gonna drop main board at my analyzer tech to be fixed, and a couple cables repaired and the sun wil be going again, yipee.

the garage i took the car to did not have any type of diagnostic equipment at all.

the only reason i brought car to that garage is because they were 65.00 hour , everybody else

wants 89.00 to 100+ hour for diagnostic work.

the mechanic replaced my tierod end on 86 surburban today , with success, but the car was a total failure!!!!!!!!!!!!!!!

il have alook under the hood again my self looking for damaged wires, and have my brother drop the ramps back over here, so i can look under the car and trace all wires.

which needs a couple capacitors replaced on the main board and the printer cable repaired. fixed.

as far as i know since i owned the car, since last march, no transmission work has been done.

what ever is taking draw,,,,,,,is feeding back power is traveling to one of the 2 thin wires on the alternator plug.

i took fuse #17 so draw stops while car is parked. to stop the current drain.

i wish this bad luck car repair on nobody.

worst case car ive owned, ive been working on cars since i was 15 and went to technical colledge for 3 years. +3 years training in high school.

i was a mechanic for 1 year professional.

then i got into roofing. money was better.

i still manage to fix 90percent of my car repairs my self.

hopefully i can manage to figure out , whats wrong with this terrible car.,

thanks jeff
