Before I go any further, I must add that I am not an electrician! However, I have almost finished a complete restoration of my Gordon England Cup (started 5 years ago). I have just finished the re-wiring, using armoured cable at great expense (!). During the restoration the dynamo and voltage regulator went away to be refurbished (I can't remember the guy's name, but I believe he's well known) The dynamo was fitted with a new armature and was converted to 12 volts, it also now has an electronic regulator.
My question is; when I turn the ignition on (coil engine) the amp meter shows maximum charge without the engine running. What, if anything have I done wrong?
Hi John,
Most of our experience of electrical systems has come by sorting these sorts of problems out, you pick things up quickly that way!
Firstly are you sure the ammeter is wired up the right way round? Try turning the lights on without the ignition, disconnect it if need be. See which way the ammeter kicks - it should discharge. If the wrong way round, reverse the two wires on the back.
A maximum discharge sounds like a short in the system. Trace down each leg of the circuit with a multimeter disconnecting bits and testing for resistance to earth (or lack of it, a short circuit). It's easy to get something wired round the wrong way with non coloured cables like the armoured stuff, you've probably got a live down to earth somewhere?
I hope you find it and it's an easy fix. Let us know how you get on.
