Subject: Heres a strange one for you!

My throttle got stuck open on my 76 2002. Its all stock 80,000 og miles. Runs strong, everything works. However when it was stuck open it made a strange grinding sound so I pulled over, at the same time noticing the turn signals, and windshield wipers didn't work. Horn didn't work either. Ofcourse I started checking other electrical components when the first two quit. After I figured out where the grinding came from, (the carb) I unstuck the throttle and all electrical components work once again. Any insight on this or is it a strange coincedence? Help me with my spelling also if anybody has the heart.

Rusty pedal boxes are known to have sticky throttles. 76's had the most problems in this area due to poor drainage. I assume the car was or is still in the rust belt. If not, you should check the links at the carb for freedom of motion and look at the return spring if there or not.

On the other hand; having an electrical issue that seams to be related, perhaps one of the under dash/ engine bay wires has gotten entangled in your throttle and pulled thus exposing a short?

I dunno, just a thought. Stranger things have happened.

sounds like a grounding problem. add a thick ground wire from the engine block to the body. you have to do this as otherwise your throttle pedal and rod will act as the ground.

this shows a tii - but it's still the same as your carb'd model=
open the hood work yout throttle linkage thru
it's full travel and find where wiring is touching.

are you missing return springs ?
One at the fire wall
One down on the side of the pedal box seen from the outside
On the carburetor
Get lubricating......
your brake linkage will imitate your throttle soon

And as noted above - WHY DID IT STICK ?
That Can Kill You !.
Fix it TODAY.

KUDOS TO CD! Thank you for these terrific diagrams. You must be very good with autocad or something. You are very talented and thoughtful. Thank you!

He works at a BMW dealer, if memory serves. I think those diagrams are a perk of the job and access to the factory manuals, or the result of lots of gleaning over the years. Or both. Whatever--I appreciate them too!
