Hi all, Very new to bikes, this is my first and so far I love it. It's in a bit of a sorry state but piece by piece have been restoring it with many plans to come. Anyway long story short - Bought bike 2 weeks ago. Lights worked at time. Booked bike in for MOT on Wednesday, one of the failures was 'brake lights not working'. Bloke says he couldn't get any lights on, regardless of what ignition location. Poo-poo'd it till I got home hoping for the best, but low and behold no lighting. Checked fuses coming from battery, positive fuse burnt out. Went and got new 10a fuse from Tesco and fitted. Now the negative fuse - whenever I turn on ignition - glows bright red. What am I looking at here? I'm totally clueless with electrics! Bike runs cushty apart from that! Looking forward to documenting my resto on here for those interested.
