Greetings BlueManLou,

Welcome aboard! I think that you will like it in here. You will find super people from all
walks of life who share your appreciation for any and all things GMT400.

Speaking of which, those Factory Service Manuals are the gold standard, and they cover
all flavors of the GMT400 family, Trucks, Suburbans/SUVs, Caddys, GMCs, and even the Bow Tie stuff.

As @South VA alluded to, I share a similar background, got to do 20+ years in Flightline Avionics,
C-130 & F-106, big break of service, and then most of my time on F-16s like these: Green Mountain Boys

If you were comfortable with the Wiring Diagrams in the T.O. Library, in no time you'll be able to
find the answers you're looking for in the General's manuals. I have no doubt that you will be able to turn
back the hands of time on your truck, and fix those electrical issues for a lot less coin than trading
it in on a new truck. Your boss will be astounded. :0)

BTW, nice truck! 8-luggers have a bit of a cult following in here.

Glad to cross paths with you.

Hey Road Trip!

It is great to cross paths with another avionics guy, and F16s to boot... but wow F106's.. very nice. I joined in 82, and got out in 94, but then did some time in the USAR in 2004 and played in the sand for about 5 months before getting discharged. I later joined the USAFR, but they wouldn't let me back on the flightline because of hearing in one ear... so where did they put me... Power Generation... LOL generators... in a CE Squadron.

Anyway it is great to be here, and I am itching to start tearing into the truck to get the lighting issues fixed.

I had issues were the blinkers would stop blinking when I stepped on the brake, then no taillights but brake lights good, as well as no blinkers in the back when I turned the headlights on...

I checked both rear taillight assemblies and found corroded sockets and a bunch of nastiness on both of them. I changed both assemblies out, but it seems I have no tail, brake or blinkers... I think when I took it apart I agitated a loose ground somewhere, as now I have zero lights in the back.

I have downloaded all the 91 service manuals off the linked page, so now I have some documentation to work with.

It will be fun

Thanks again and glad to meet you and be here with all you all!

Welcome to the forum from Oregon.

 

[BlueManLou]

Welcome from the the great white north.

I worked on Corporate aircraft for more than a few years.
A.M.E. under F.A.R. 27.853. (Interiors)
A refurb center. 85 employees.
We did new everything. Paint, hydraulics, avionics, entertainment systems, complete interiors.
I've watched an avionics guy sit on a 8" high plastic stool in front of a fuse panel for a week, 8 hours a day. Messing with a 4" bundle of wires of about .032 in size. All white. Individually fused. I.D.'d by the black multi number/letter code printed on the wire.
No color coding.
Cycling through however many times the regs dictated at the completion of each section. If that's say, 25x, and something's not quite right on the 24th cycle, they're starting over.

Big props to you avionics guys.
People say I have patience to do what I do, but that would have me blind, crippled & 3/4's off m'rocker nutso, mentally worn-out, by the time the aircraft left the hangar.
I couldn't do it.

Hey Sewlow!

Thanks for the greeting! I am glad to say I never had to sit and do that kind of rummaging through wires like that, but I had my share of wiring harness troubleshooting. Unfortunately it was quite awhile ago, so getting back into it that deep will take some doing. I am a computer network guy so basically that has limited my wire troubleshooting to cat5/6 ethernet and a little fiber.

Thanks again for the welcome, and I am glad to be here. Stay Warm!

BlueManLou,

I just looked through a few different manuals spanning the years, and I can understand
your confusion. Some said "Chevy Trucks", which might imply Chevy only?
And then for a different year, the cover would only show 'GMC'?

In addition to the .pdf versions I use on my laptop, I bought myself the
paper 4-volume set. Here's a recent photo with all 3 logos on the front cover.

FWIW --

Cool, Thanks Road Trip

Nice! I swapped boxes on F-15s and F-111s as well... if that's any consolation... B1s ... nice...

Welcome to the forum from Oregon.

Thank you!

Hey Lou, welcome from Florida!

Hey Rich,

Thanks for the welcome. How is it going down in the Sunshine State? I went to high school in Jacksonville, and was out in Ft Walton Beach for about two years before going overseas and getting stationed right back in Florida at MacDill in Tampa. I was there from 85-91.

Really liked Florida.

Welcome! Nice truck.
Weather in Iowa looks great!

Thanks!

Well the weather has been great here in Iowa lately, but the pic is from when I was in Georgia, probably about 2017, so the truck was a bit younger then.

I need to do a lot of cleanup work on her now.. but she is still running good.

That's what the set we ordered from Helm back in '05, for our first '99 Burb, looks like. And this particular volume you've pictured, is the one of the set that I'm missing.
