My Fatboy was just starting to get a bit slow to kick over and start, so I charged the battery and it worked fine, my mate is a Auto Electrician so we put the Meter on the battery and found out it wasn't getting charge, so we got the specs and with the meter we found out it wasn't the stater, so we went for the Regulator, we ended up taking it off, I thought it was stuffed but put it back on to get home - it was working again.
Might have been the connection we cleaned up or the earth wire - anyway I was thinking money!!!! and got out of it for Zip for a change. Great having an Auto Elect I can trust and does stuff for me for a packet of smokes.
