78 Brat Wiring Diagram


Recommended Posts

I can get one to you later in the week if nobody else does. Old computer had them on there,never got them over to the new rig.

 

Anything specific you're interested in know about?

 

Some considerations:

Always check the fuses -take it out and pull on both ends -they can be deceiving.

 

Doesn't stay running for more than a few seconds? - change alternator and voltage regulator together - same time.

 

Just 2 main culprits worth mentioning. Let us know if you still need help.

I'm not dealing with any particular problem. We're waiting on an engine. While we do, we're going through the other systems to make sure the car is ready when the engine arrives. There are several user provided wires. There are also a lot of splices. I want to get it back as close to original as possible on the wiring. If you are able to dig out the old diagrams it would be a huge help!

 

Thanks,

chris

At this moment I can't find the Brat supplement I know I have around here. Might be out in my '78 wagon. And although I do have the '78 1600 FSM with all wiring diagrams for the sedan,coupe,wagon and 4WD wagon it's a 5 or 6 page fold out and I need to run to see my dad in the hospital...so maybe tonight or tomorrow.

Good news is my dad is doing much better now.

 

But I'll have to scan stuff later,just too beatup and need to sleep soon. I used to have all those on my old computer,but that's life. :rolleyes: I'll scan the sedans and 4WD wagons but I think my Brat supplement was left in the Brat at my inlaw's. Not far away,I'll get that tomorrow or soon. Tomorrow is a full day with retrieving my '87 Turbo wagon.

Ok here's some wiring diagrams.

 

Cover (for those interested):

On back it says "Covers: Sedan, Coupe, Hardtop, Pick-up and Station Wagon with 66.4, 77.3, 83.1, and 97 cu in engines. Covers all 4WD and MPV models including BRAT"

1977 Sedan (one page):

4WD MPV (Also Brat / 3 Pages) They all flow together if you tape them as one it makes it really easy to follow:
