I am going through the electrical system on my 74 914 2.0. Overall, it is in decent shape, but I could use some guidance in a few areas:
1. Turn signals work fine, but dash indicators for turn signals do not. The dash indicator lights consistently light once when the hazards are truned on, but I get nothing when the turn signals are used. 2. A red light on the dash blinks all the time. There is writing similar to this - ((( ))) on the light. If I understand correctly, this is the brake warning light. What causes this thing to flash? 3. Fuel gauge only registers fuel in the tank when the headlights are turned on. 4. There is a temperature gauge in the center console - see attached picture. Is this oil temp? The needle on the gauge moves when power is applied, but the temp never increases. My guess is that the sending unit is bad but I wanted to get another opinion before testing mine and/or ordering one. Thanks. Bob |

I'm not sure about the turn signal lights, but the flashing brake light is usually caused by the switch not activating correctly. It's located under the emergency brake to the left of the driver's seat cushion. Try to push it in with your finger to see if that causes the light to go out. Sounds like it just needs some cleaning/adjustment.
The temp guage may not move much (I don't remember my 74 too well). You can check the sender (found under the engine screwed into the small round plate (taco plate) by immersing it in boiling water and see where 212 degrees shows up on the guage. There are wiring diagrams (actually current flow diagrams) posted on the Pelican Parts that should be helpful in tracing the circuits. |
