Hey Kenny. Great video. One tip that I learned at GM training was to open all the doors and set all the latches including the hood and trunk lid/ lift gate. Also if you have to pull fuses, always start at the rear of the vehicle and don't ever put the fuse back in unless you have found your draw. If you remove a fuse and put it back in you could wake up modules and have to start your test all over. Another tip is install a fuse holder in one or both of your meter leads. Install a 10 amp fuse, this way you can protect your meter fuse.
I've been there so many times I bought fuses for my Fluke 88V in bulk. After doing that, the humiliation of being stupid was so profound, I never made the same mistake again. One day when thermal camera prices fall I hope to use one of those to identify the fuse, and I've been intrigued by guys who use voltage drop across a fuse to nail down the circuit without removing the fuse. In the end, as you say, it's usually pulling the fuse that nails the diagnosis.
dic driver information center its in the cluster gm says 50 ma or below ive had them take 45 minutes for everyone to go to sleep if you get a gm reman the odometer has to be programed at chevy and if you drive it the program gets locked out ive worked at chevy 23 years now 10 in the aftermarket
Thank you! Very well done! In other videos the lead was not connected directly to ground but to the negative cable that was just unhooked. I can see your method might just be a lot better.
Ebay has some cheapo (but useful) clamp-on current meters with DVM functions. They are super handy for this kind of stuff and you don't have to worry about fuses.
Another great video. i have 99 GMC Jimmy that has a pretty good draw. keys out of ignition, I can hear 2 things under the hood area come on when hooking up the battery and heavy sparks while hooking up the battery. Will have to try this test and see what happens.
If you have or suspect a heavy draw , what I would do is get a 10A blade style fuse and make a fused jumper wire . Then connect it like I did the meter to see if you have a large enough draw to pop the fuse . If it doesn't, then use a meter. This will save you the aggravation of possibly popping the fuse in the meter . Some of the fuses in multimeters get expensive. The one for my Fluke is $26 !!
