No Brake Lights -

Hope that some one out there can diagnose a sight unseen electrical problem.

The dealie is no brake lights on my 80 SC.

I was trying to diagnose it this weekend via wiring diagram, and dvm. One suspicious area is that the engine / tranny were just out for a new clutch, etc. While in the engine compartment I removed the non-functional cruise control and components. The CC vacuum hoses had been removed by a pervious owner, but I can’t remember if the wiring was hooked up or not, or how I remove that. I'm not a wire chopper, but I do hate stuff that doesn't work, so it had to go

Any ideas or suggestions how to start tracking this down?

I had this problem some time ago. There are two pressure switches on the master cylinder. These get clogged over time and stop working. I just changed them and everything worked ok.

You can try searching the forum for more particulars.

Pressure switches on the side of the master cylinder. Our host sells them. Solved my problem.

Go to BowWow and purchase two brake light switches (about $6-8 per).

Use the Search mechanism on "brake light" or "brake switches" and read up. If you can dovetail this work with a brake bleeding you are in good shape.

Easy fix to a classic problem on our SCs.
