Since I now have a lot of stuff working that didn't work before I guess I am going to come up against new "gremlins". The voltmeter acts like a metronome when the turn signals are on, is this normal for a 914 or do I have a problem some where? The voltmeter drops to around 10 volts when the brakes are applied so I wondering if the brake lights draw that much and is all this related?

This behavior is normal in a 914, because the voltmeter is measuring the voltage at the fuse-panel, thus detecting the voltage drop along the supply wires.
If you really want to fix the problem, run a separate lead back to the battery. You should switch this lead with a relay so that you don't drain the battery when the car is off. Control the relay with the original voltage sense lead. |
