No brake warning light solid or flashing in 1973--help please Options

[914xr75]

It's me again. A couple weeks ago the World helped me with proper bleeding of my daughter Lilly's car. Now I am trying to get the brake warning light to work before the WCR. It has never worked in the past nine years, flashing or solid.

I am not good with electrical issues. I know how to check my battery with a freebie Harbor Freight dmm, but that's about it. So here are the details.....New 17mm ATE master. Brown with yellow stripe wire connected to the new master. I have pushed the reset button. Brakes are properly bled and there are no leaks.

The turn signals work properly. The flasher works. The seat belt warning light has never worked for 9 years. i checked that the bulb is good for the warning light. All the terminals at the bulb base are connected. I think there are 3 spade connections.

I didn't see a fuse listed for the switch. Someone in a previous post mentioned a diode near the warning light. I'm hoping there is an easy fix for this problem or I will have to take it to an auto electrician. The warning light doesn't work for the e-brake as wall.

Thanks in advance for any assistance. Sean

From the fuse block...Fuse 9 feeds power to the fasten seat belt light via a black wire through the ignition switch. It then feeds the parking brake circuit via a brown and white wire. it also feeds the brake warning light and yes there is a diode in that circuit.

The brake warning switch should have 2 wires, I believe one is ground (brown wire) and the other I believe is a brown/white wire.

It really comes down to checking the #9 fuse, seat belt light, parking brake switch, or brake warning light switch and the brake warning light bulb itself. If all of the switches are good and the bulb is good that really only leaves 2 things left, a bad diode, or a broken wire. Those 2 things aren't very likely, but these cars are over 50 years old, so I would never discount any possibility.

Let me know what you come up with. If it will help I can send you a wiring diagram.
