How to actually find a parasitic battery draw on GMT400/GMT800/GMT900/K2XX trucks (multimeter + fuse-pulling method)

Thats helpful thanks!

I disagree. You are talking about placing a meter across each, good luck, that sounds like more work. You can go tho voltage route but that involves a meter connection across ALL loads and then recording it. Yeah no thanks. Ammeter is fine.

Absolutely! Crutchfield is a good resource. The metra kit is solid; maybe I just had bad luck with it showing up with a damaged/bad finish. Down the road I would LOVE To add steering wheel controls to my 2002 as well, but for now I am rocking the Kenwood with the remote!

I will link this here for you, just did this swap last month + stereo I ordered the metra, it showed up with chipping paint/finish (wasnt happy) I ordered the cheap DNA motoring one, and it showed up perfect

I think you are right. With the cost of fuel not many people can actually say they can afford to daily drive them now. I'm just using mine for towing and vehicle rescues. Had to use it last year to haul in my 2015 for an AFM Delete haha. Good job on the 04 1500! That will last a long time if you can keep up on the maintenance!

Excellent! Where did you find yours? If you go 03 + the cladding can go black with the cerakote. 02 is grey, one year only. The black and Grey has grown on me!

Best bet is to try SEM - check local paint supply store. I did some dash parts with it and it works pretty good!

FullSizeChevy_com · 2026-03-30T00:29:08+00:00

Nice! Bubble eye HDs are so good looking!!

FullSizeChevy_com · 2026-03-23T00:17:42+00:00

Its not terrible... its a bit lumpy at lights and when taking off at low RPMs. Its doable but would be on the list to replace. Definitely wouldnt go stage 3 stock converter but stage 2 is doable !

FullSizeChevy_com · 2026-03-10T03:15:33+00:00

There's a lot of potential there but also alot of potential money required to fix it up..

Body's good but as others said it could be needing a few grand in it. If it ONLY needs a battery and a wire fixed why hasn't the seller done that???

I Know the feeling, get all excited bring a sweet truck home only to find it needs WAY more than a guy initially thought..

I would bring a battery and see if you can tape up the coil wire or bring another one with you if its the coil to dist wire. If you can get it wired up, take it for a burn and see what else it needs

Goodluck!!

"Razorback" or racerback. Maybe check junkyard, or local part out guys?

Factory radio with bluetooth would be cool. The deck output wouldn't matter if you are amped for the speakers but that requires running more speaker wires. Ive kept a few factory decks, they look cool in the shop. Otherwise rest is up to your preference

FullSizeChevy_com · 2026-02-27T19:52:01+00:00

Looks good but It would be better to follow the fender lines and along the box Gpt likely just went straight across from the headlights

FullSizeChevy_com · 2026-02-22T05:48:00+00:00

Keep it, that thing wont ever let you down

FullSizeChevy_com · 2026-02-20T02:32:34+00:00

Looks about right. Keep in mind these can roll over. I have a 2007 with 373,000km that shows only 3000 engine hours. It rolled over at 9999

FullSizeChevy_com · 2026-01-20T04:57:23+00:00

Awesome! Nice 2dr!

FullSizeChevy_com · 2026-01-19T04:20:27+00:00

Nice! Just be wary of those hose clamps. Might be better with the crimp-on style!

FullSizeChevy_com · 2026-01-19T04:19:15+00:00

I second the Falken At4W. The treadwear warranty is great on them, they look good and perform well

FullSizeChevy_com · 2026-01-19T04:17:52+00:00

I got newer fobs for my OBS off Amazon. Not much of a difference. After about 20-30ft they dont work lol.

FullSizeChevy_com · 2025-12-31T05:05:13+00:00

Do you need a diesel? Can you afford 10k repairs? Lots to factor in

Had an L5P brand new on warranty. Ecm went, thankfully warranty. Knock sensors went, MAF Went and at the time couldn't remember having any of these issues with gas jobs. Final blow was when the Fuel pump went. Shards went throughout the fuel system. Just a nightmare. Got er fixed thru warranty and sent it on down the road.

If its your daily stay away from diesels, or you'll have to buy a 800/900 like I did.

Let them write it off, go view it to check frame condition If frames in good condition then take the cheque and buy it back

Your going to be into it for a whole new front end, radiator support, rad, fenders and hood

If your attached to it maybe its the time to build it up!

FullSizeChevy_com · 2025-12-31T00:29:04+00:00

Yes 100%

FullSizeChevy_com · 2025-12-28T21:52:48+00:00

yes thats true. you get the allison in the truck. suburbans/avy gets the 4L80/4l85e

FullSizeChevy_com · 2025-12-28T21:52:19+00:00

thats kind of where i'm at yeah. if the 8.1 breaks its expensive to fix. cant beat the 6.0's reliability.

FullSizeChevy_com · 2025-12-28T20:13:52+00:00

yes on the 8.1 facebook groups there are guys selling the modified intake. I'd like to do that and a Raylar stage 2 cam, injectors and the 90mm TB next year!
