Non Yam bike related, so here goes
Having neglected working on my 59 Speedtwin for a wee while, I set about it with gusto these last few days. Finished all the wee jobs, added oil and petrol and went to fire it up. 2nd kick having stood unused for God knows how many years so I was all chuffed. I had left the exhaust off so after fitting them I tried it again, Nowt, as in no power....a blown fuse was the culprit however every time I replaced the fuse it would blow again. Tried a few things with the multimeter but all negative results. Finished late last night and asked for help on a couple of Classic bike forums. Anyway back at it today, and having thought about it whilst out running this morning I was thinking what had I done.
Some breakfast down me and out to the shed armed with some AC/DC and a cup of tea. I started to isolate each circuit (ignition, lights, charging) when I discovered it was the lighting circuit at fault. On checking all the wiring I discovered that some pillock, that'll be me, had connected an earth wire to the lighting power block...fud.
Anyway set it all up as it should be and tried again...yipee it runs. Still some work to do, the bike wont rev up so some setting up of the carb is in order and the clutch is very heavy so I will need to look at that, but hey, it runs
