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

I just went through the brake warning light issue too:
Pull out the gauge , remove the bulb holder with bulb.
Test the bulb 1st, either in the socket out . I use a 9 volt battery.
Test the ground wire to the socket, with e brake on, you should see continuity. If you get continuity and the bulb is good, test the other wire for 12v. With one probe on chassis ground and the other on the green/black wire you should get 12v ( Ignition switch has to be on) If your turn signals work, you should see 12v
