Please help, electrics gone tits up

[nobby81]

Mot booked for Monday and the bus has just developed a fault. Everything was working fine driving with lights on until I indicated - stereo went off and generator light came on, now happens every time I indicate and remains after indicator turned off, only goes back to normal if I turn hazards on, hazards work fine still. WTF ? Why now? dodgy relay? dodgy earth or would that effect hazards?

Any advice appreciated Thanks mike.

Have you checked the voltage output from the alternator or dynamo under load?

Can't help sorry . But if you bang this up in the tech section you'll probably get a better response mate.

Electrics do funny things with the lack of voltage, I was on my way to Malvern when I first noticed my bus wasn't charging under load, lights, stereo etc , first the radio cut out, then the lights dimmed, then the tail lights turned into very faint candles, then the coil played up, was fine when on sidelights.
