Thanks everybody! I'll give it a shot with a 10 ohm then if nothing happens I'll send it of for a refurb. A chap named Berni was suggested by Powabyke.
Thanks. I removed & tested the C12 capacitor & it seems ok. The blown resistor at R19 is bigger then everything else on the board so I'm not sure. You're probably right that something else is damaged but I'll cross that bridge later...once I've worked out R19's value.
Help! I've managed to put reverse polarity through my powabyke. It's a 2000 folding bike. Having opened up the controller, there's clear damage to a resistor in position R19. It's so burnt that I can't read the colour codes. Do you know it's value so I can start by replacing that? Thanks.
