'89 Fun daily build

@Wh4t3v3rs

Got the truck back but the installer said the right channels on my amp, which I had installed years ago but was done very poorly, are dead. I tested voltage on the inputs and outputs. The inputs are good but the the outputs for the rights channels are reading -2.3 while the left are reading 2.3. I've tried looking into this but I haven't been able to find anything. Does this verify the the right channels on the amp are gone or something else?

That means your output on that channel is shorted.... that sucks!!!! I don't have JL Audio, but I do have Hertz Audio. if you wanna replace that amp PM me and ill se what my cost is on a replacement...... gotta help out a fellow GMT400 and audio guy!!!!

Done! Appreciate it

Back to updates:

The mps250 sounds great in the box he made, so I'm happy with that. I'll get some pictures of the wire runs later, he took quite a few while working on it. He didn't do the security system yet because he said for older vehicles he uses the tach line so he wants to wait until the Dakota dash is in. Tint looks great from what I've seen so far, I need to look more closely and also get some pictures for you.

Unfortunately I found out on the ride home that the front driver side tire rubs the quarter panel. Not sure why, this combo should have clearance based on the numbers. I'm waiting to hear back from the shop that installed all of it.

Next week the plan is to get the parking brake cable replaced since the one they got was too long and at the same time get the steering shaft put in. Then it's off to get the temperature sensor put in, hopefully that fixes the check engine light and rough idle, neither of which were present when I dropped it off originally. After that I get to make a trek to the one shop I've found that has experience with Dakota clusters to get that put in. I hope I can get that all finished by next Sunday.

Yikes!!!! Not what you want to happen to fresh set of tires! Looks like you have to roll the fender, or new set of wheels with different backspacing.

Well... it got worse. I have to pull into my tiny alley driveway because it isn't registered yet. After a short test drive to make sure everything was good after putting in a new coolant temp sensor I scraped the front passenger wheel real bad and the tire has a bulge in the side wall.. Was going real slow too but that didn't matter.

Could be worse, it's "only" a tire and a wheel but it's still upsetting

Alright, taking a look at it again with a more cool head the right tire might be fine, need to pull it into the garage and find out. The curb rash will just be a project to tackle at a later day, I'm no stranger to sanding and polishing. Pictures attached.

When I've got it pulled in I'll also roll the fenders as best I can with a mallet and heat gun so I can get it to the shop. The shop feels bad about having missed the overlap and are replacing the tire and will also be rolling or cutting the fender lip while I'm there for the other things.

From this


To this


Took me a while since even the front fenders are double walled. Also because I started with a rubber mallet when really I needed a soft face hammer. More photos attached. Hopefully this is enough to at least get me back to the shop.

Since the tire was off I also got a picture of the new brakes and control arms.

I still need to get more photos but my focus has been on other things. Here's one with one of the USB ports. There's one on the other side and both connect to the Headunit.

Thanks to some help from @Wh4t3v3rs I got a new amp and installed it today, found out either my right rear speaker is dead or has a wiring problem. Either way it's no real loss since it's a stock speaker. System sounds great with just the fronts, sub, and a rough time alignment. Very happy with how it's sounding at the moment.

The truck is now off getting the Dakota cluster installed, it'll be nice to have working gauges again. The drive was nice, hit a fairly large bump and it didn't sound like the tire hit the fender so the roll might have been successful. Aside from steering and uncomfortable seats it drives nice now. Very responsive, hooks up, brakes better than any vehicle I've had, and in general is just a pleasure to drive. Unfortunately it couldn't all be good news, the cruise control died on the way so now I need to look at getting that fixed too..
