[QUOTE="moto8500, post: 157363, member: 4798"] Thanks for the replies. The vibration theory is a good one but does not explain why the needle does not swing wildly when there is no load in the circuit. It's a Alton 12v ACGO1 with two wires coming out and four wires ( yellowx2/red/black) from the rectifier. The battery charges on trickle and holds the charge and seems to be charging according to the ammeter needle when there is no load in the circuit. With the needle swinging from + to - to + again when a load is applied I wondered if the a/c from the Alton was bypassing the rectifier but then the headlight would flicker surely but it doesn't. Wiring looks all good at the battery end so I need to chase the earth and as a starting point where should I look for it? [/QUOTE]
