MKIII Headlight Problem

Supra275 · 09-05-2008, 09:06 PM

The battery charges ok - when the engine is running the battery terminal voltage is approximately 14.1V at 2000 rpm with the headlights / lights, rear heated window, heater blower and fog lights ON. The battery holds charge ok for over at least a week. When the lights flash they are at full intensity as it is the headlight relay coil which is being switched – checked by using a LED / resistor across coil socket in the fuse / relay box.

Interesting – the stereo ( not original factory fit ) will not operated at higher volumes – its LED display flickers with the music and sometimes the radio cuts out and restarts as if it were switched OFF and back ON again. I assumed it was a high resistance contact somewhere in the supply cable or fuse and would fix it at a later date.
