    Brake light grounding

    Hello, 1978 GMC K25 fleetside. After doing quite a bit of work to the truck, I now have no brake lights. I did a new ignition switch, ignition lock cylinder, and had the box pulled a few feet back for paint. All lights worked fine before this. Tails and Turn signals still work fine. I jumped the...

    Brake light issue I can't get smart to

    I had to pull it out of place and reinstall it for the lock cylinder. I don't have any brake lights even when not signaling either.

    1978 k25 stalling issue

    Hello, I have a 1978 k25 with a 350 engine. The previous owner installed a new ignition switch and distributor. Ran great for a while, then started intermittently dying on me. I first ensured I had good voltage to the HEI, which I did. I replaced the distributor, which didn’t seem to do...

    Strange brake issue

    Hello I recently bought a 1979 Chevy c10 with a 305. When i bought it it had absolutely no brakes. I put two new front hoses on it and got front brakes, but haven't bled them yet. I then had to replace the long rear line (rusted) to get rear brakes. There seemed to be some rear brakes in it but...
