Brake lights & Turn Signals not working
#1
I had brake lights working a few weeks back but they have quite again.  I pulled brake switch and tested it (works).  I have 12 vdc at one side of the switch plug from fuse panel.  I jumped the wire but brake lights do not come on.  I also do not have any turn signals.  I do have tail lights and front parking lights.  Could it be the flasher that's near the fuse panel (or one that's on passenger side of dash).

thanks

The brake light circuit runs through the turn signal switch. It's probably either the switch or the connection on the steering column for the turn signal and horn wiring.

Don C you were dead on. Somehow the the big connector had been pulled loose. It's hard to put together or pull apart but it's together now and everything appears to be working. I need a few new bulbs and maybe a few new light sockets.
I noticed the sockets have a ground wire connection but most of the newer replacements do not have a ground terminal. Is this ground on the socket needed? I pulled one loose and the light kept burning.

If they are mounted in a plastic housing they need the ground connection. I have seen some plastic housings with a grounded metal ring the socket grounds to. Dual filament bulbs can back feed from one filament to the other and seek a ground through the other circuit. It will seem like it is working until they are both turned on, then neither one will work. The sockets must be grounded in some way for the lights to function properly.
