Okay, relatively good news for me tonight, switched out the 20A fuse and we got power, I can actually still get the multimeter to beep with the blown fuse every once in a while so it must be a slight break in one of the ends anyways all good there. Shaved off the paint on the bars and we got e-start again! And finally I took apart the left hand switch and voila two broken solder connections, I haven't looked at any diagrams yet but if anyone knows which wire goes where that would be great and also as I was taking the switch apart the round thing in the pic fell out before I could get a picture, it might only go back one way but I might as well ask now while I'm at it, does the extended part go down or up? Anyways I say that's 3 for 3.... just need to get a soldering iron now and it doesn't look like an easy solder job, tips definitely welcome.
Thanks!
