I had a bit of an incident with the zed last night, it threw me and pillion off due to a rear tyre leaving the rim, myself and pillion are OK just sore but the bike fared worse.
I got it recovered today and having checked it over for things it needed for rebuild I checked the engine, turned it by hand and OK, tried to fire it on the starter and nothing on the button, checked the fuses and a 20A fuse had blown, I replaced this but it blew again instantly I turned the key.
Wiring loom seems OK, nothing obvious other than LH switchgear, (non standard with only horn and hi beam switch), ruined in the fall, the alternator cover however was badly damaged and upin inspection the magnets of the windings are contacting the flywheel on the rear, could this cause the blowing fuse or should I be looking elsewhere for the fault?
I want to establish the engine runs OK and the frame is straight before I do anything else or buy any more bits, I have another alternator cover on it's way, (hopefully the right one, it's off a 77 and mines an 82F2 so fingers crossed)
