It was just with a cheap voltmeter I had in the garage. I’m going to take a multimeter home from work and have a play. I just can’t really get my head around it and I also don’t really want to pay £40 for a canbus interface just for an illumination feed.Eddie555 wrote: ↑Sun Mar 17, 2019 7:38 pm18 volts?!?!?!? I’d be looking at the voltage stabiliser in the alternator. 14.5ish volts is the norm. Are you sure it’s 18 volts??? If it is it’s probably why the radio is tripping out.
Edit. Put the multimeter across the battery terminals and take a reading. If it’s 18volts there then there’s something wrong.
I can’t understand why there isn’t a fuse for sidelights or headlights in the fuse box. I’m going to put the illumination wire on a permanent source to try and eliminate the headunit and take it from there.
