I noticed it at lunch today. The blinker indicator in the dash would flash 4 or 5 times, then stop.
Coming home I tried the e-flashers. Same deal. Maybe 7 flashes then OUT. Try the left side, 2 flashes, right side 4 flashes.... then OUT. Now I get no flashes at all. Got a few honey do things to knockout this afternoon then I will start poking around. Figured I'd start with the fuse, then relay. Seeing how it is the flasher and the blinker, I will rule out the lever and such in the column. How do you test a relay anyway? Chime in with some thoughts. Thanks, Clark |

OK... The bench test results are above. I just installed the flasher relay into the car.
Turned the key on and the BRAKE light is flashing and the relay is clicking. as expected Start the car All blinkers work as expected E-flashers work. Here is the question. 49 - 31 I get 12.8v with the key on and or the car running. I release the brake and the clicking and flashing stops. BUT with the car still running and the relay inserted, but the terminals are accessible. I check the voltage between ground and 49a and I get 13V I check the voltage between ground and C and I get 13V.[b] No clicking, nothing flashing. Is that right? What is going on? |

I release the brake and the clicking and flashing stops. Now you may be getting closer to your issue. Brakes are not connected to the flasher system at all. Note the schematic I posted has no components or connections to the brake system. I would guess there are some grounding or other wiring issues in your car. The flasher does not seem to be 100% the culprit. |

The brake light flashes and it clicks until I release the hand brake, so it has to be connected to the flasher relay, right? Your diagram and this one..... show the brake light getting 12v from 49a? Am I reading that right? I have backdated my tach and have R and L blinker lights, so my set up is close to this. |

You wrote: Your diagram and this one..... show the brake light getting 12v from 49a? You are right and I am not exactly wrong. (IMG:style_emoticons/default/beerchug.gif) The brake light getting 12V from 49a is the brake warning indicator lamp in the multi-gauge unit which includes the fuel gauge. As far as the brake pedal and the exterior brake lights are concerned, there is a connection between the exterior brake lights and the rear turnsignals. The connection is the connection of the ground circuit in the rear lamp fixtures on the vehicle. Both turnsignal and brake lights share a common ground. If that ground is somehow compromised, related issues could happen. Also it could be with the rear light fixtures that the 5 spade connectors are incorrectly connected. I have mis-wired the rear fixtures a couple of times. Probably why there are many threads with folks asking which wire goes on which terminal on the rear light fixture. |
