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 |

Below is the simplified schematic for the turnsignal network in the '74-'76 914 with the single L-R tachometer turnsignal indicator.
To test the flasher: 1) apply 12V on 49 2) connect ground on 31 3) connect known good turnsignal bulb from 49a to 31; The flasher should flash. Don't worry about C/K2, it's only drives the tach indicator bulb. If the flasher won't flash following the above test, C/K2 operation will not work either. Attached image(s) |

Thanks, I did find a similar diagram in a post, but it had a 911 tach with R and L indicators. IIRC it did not have the brake stuff on it, and IIRC my brake flasher is also not flashing with the hand brake pulled up. Shouldn't the relay start "clicking" when 1) and 2) are done above? |
