Once again need the help of the great 914 Brain Trust here........
My Parking Brake Light stays on all the time. The switch is fairly new and it is functioning properly. Disconnecting the brown (ground) wire to the switch, it has no continuity or resistance to ground. So it is not "grounded out" somewhere. I see in my great 914 electrical schematic of the ground circuit for the switch and light that there are two diodes in the circuit. I am guessing that one of them failed. Can anyone tell me where these two diodes are located? Or where else the problem might be? As always, TIA, GN |

QUOTE(jim_hoyland @ Jul 4 2025, 06:41 PM)  I'm also trying to troubleshoot the flashing red instrument light. Didn't locate the brake switch illustrated in the shop manuals, and have no good access down beside the seat. Have pushed the MC pin in several times with no effect, no leaks, and brakes are working just fine. Don't know what to try next? (IMG:style_emoticons/default/blink.gif) |
