Suzuki Club UK

Parked up, badly. Went to start her and 'click'. She's been running fine for 2 months with no starting issues at all. However on the drive home when the brakes were on the volts went from 14.5 to about 12. Now, when I turn the key the volts go from 12.5 to zero. Battery is fine, starter is fine. Sticky starter fix is on and works. I am stumped and bloody annoyed.

Any ideas?

Cable connection? Sounds like a stupid one, but my battery cables and clamps looked fine... then sometimes when starting it would clunk and then voltage would drop to zero, dash lights and everything would go off, and stay off until you took the batt negative lead off and put it on again!
Pretty sure electricity isn't supposed to work that way, but it is Suzuki special electricity

Could be mate. I'll have another check over everything, and I do agree about the 'special' electricity!
