Where is the ground numbered #83 (Ground connection "B") on a 1970 914? It's not the one in the rear trunk, and not the one by each headlight. It's the one that grounds all the dash switches, door switches, fan and heater switch, etc.

Alright...new evidence. I have all the gauges dangling and nothing is loose or missing that I can see or feel, but check this out... When I turn on the ignition, and make the flasher click like crazy by turning on the lights, radio, wipers...anything, I can make it stop by turning on the emergency flasher! Once the emergency flashers are on, everything else works fine and the buzzing stops.
I'm guessing this is because the flasher relay is getting more juice and Ill just have to ride around all the time with my 4 ways on, or is this some evidence of where the problem lies? |

I'm guessing this is because the flasher relay is getting more juice and Ill just have to ride around all the time with my 4 ways on, or is this some evidence of where the problem lies? It makes sense that the 4-ways stops the noise. See below, with 4-ways on, power comes from fuse 11. Fuse 11 powers the 4-way lights, clock and the seat belt warning system. Fuse 9 (in my Haynes manual looking at 1974 MY) which powers the system when 4-ways are off, also powers the brake lights, backup lights, oil temp gauge, voltmeter, generator light, low fuel warning light, and fuel gauge sender unit. oil pressure indicator light, tachometer, fuel gauge. Question: Does the noise stop when either turn signal is active? Question: What is the voltage on fuse 9 when this happens? Make sure you measure the lug opposite where the power comes in. Question: does the noise happen when the backup lights are on? Attached image(s) |
