Tail light keeps blowing fuse

[AllanC]

A curly one (for a bear of little brain like me anyway). I put a new tailight and indicators on and everything seemed to be working fine. Then the main fuse blew out, replaced that and now the tailight seems to be on full all the time and when I apply the breaks, it dims. To top it off, it keeps blowing either the main fuse or the taillight fuse. Any thoughts on what I've done wrong?

Earth and Tail/stop light conductors are reversed. Earth should go to "common" pin of the bulb, tail light to other pin, stop light to the remaining pin.

I suspect your tail light is wired to one filament and the earth wired to the other filament which means both are on at the same time. The stop light is then going to the common which may or may not be connected to earth by other means, so applying the brakes creates a short circuit - blowing the fuse.

well maybe anyway

Thanks for that, I'll try it and let you know if it fixes the problem (I'll have to buy some new fuses first though, ran out of spares).

Well, that seemed to work. At least I kept swapping the wires around until the problem went away. Anyway, all good now - thanks.

Sweet, all's well that ends well
