1999 GMC Jimmy, 2 door, 2 wheel drive, 60,000 miles, 4.3 liter, V6
This is an intermittent problem. While driving the battery will begin to discharge and then the car will stall. Trying to restart will yield nothing-- no starter noise, nothing. Sometimes it can be jumped and sometimes not. At one time I had to keep the portable power on the car in order to keep it running. The battery is good. The alternator is good. I have also checked the continuity between the alternator and the battery. With the car off and no accessories on, occasionally there is an amp draw of around 10 amps. We pulled all of the fuses one by one both under the hood and in the driver's compartment. Using a light connected to the negative battery terminal and negative cable, it burned brightly until the 15 amp radio fuse and instrument cluster fuse was pulled. This fuse is located inside the car. Then the light pulsed and was dim.
Could the ignition switch be faulty due to the intermittent nature of the problem? Also, last Saturday I was having the same problem. I tried to start the car and got nothing. I let it set for about 4 hours and tried again. This time it started.

First off, I don't know how in the hell you can determine how much draw you have with a test light. It can't be done. There are a number if reasons that test lights are obsolete for checking draws, the biggest being that the truck is full of modules on timers that don't stop drawing immediately and you have to wait for them to go to sleep and disconnecting the battery restarts them.
Charge and test your battery before doing anything.
There is a procedure for finding a battery draw like that.
You will need a digital ammeter and a jumper wire with clips on the ends to do this.
First rig any door switches so you can have a door open without triggering the interior lights and unplug the hood light. Remove one battery cable and attach the meter in series between the battery cable and battery post. Take the jumper wire and also attach it the same way. Leave the jumper wire on for at least 10 minutes to expire all the automatic timers. Now remove the jumper wire and read the meter. Anything over 50ma is too much draw. The way you locate this is to start removing fuses one at a time until the meter drops to normal level. This will be the circuit with something staying on. Determine what components are part of that circuit and check them individually until the problem is isolated.

Man, you have a bit of a sour disposition. How in the hell did I do it? I used an meter which allowed me to read the amps. There you go. Next time I will be even more explicit in my description of my problem. Once again, the amp draw and the flickering light(are you bothered by flickering lights?) occured when the radio, 15 amp fuse was removed.
I hope your responses to other inquiries are more pleasant. Does my response mean I am no longer welcome to use your Carjunky.com website.
