Guys Opening this one up to the brains trust - setup is a bit complicated but here goes: Tail lights were working fine, brake lights weren't at all from either switch. Bulbs were fine, fuses were fine. I found a disconnected spring at the rear brake light switch, put that back together and now the brake light works fine from the rear lever. Excellent. This is odd though, the front brake lever isn't turning the brake light on - what were the chances that both brake light switches were rooted?!? Took the front brake light switch off the switchblock, cleaned it up with WD40 and did a quick multimeter test. Yes, it's an open circuit when the tab isn't pushed in, and a closed circuit when it is. Connect that to the wires though, and push the tab in, and I get no brake light love. So the switch itself is fine, as are the bulbs and the fuse, 'cos it's working from the back brake light switch... I followed the front switch wires back into the switchblock and it all goes into the loom and off into the frame. I can't see any connection issues. I haven't farted about with any wiring lately... Any ideas what the problem might be? Bonus points for a quick 'n' easy magic bullet solution! Added degree of difficulty: I'm almost completely useless with a multimeter, so any solution that involves one will have to be explained as if to a 2-year-old. Thanks in advance!
