Any auto electricians on the forum?
The HT coil has packed up on my Guzzi Guzzino 65cc bike. New coils are not available as far as I understand and people who have had there's rewound have complained of them working ok for a while only to fail again.
I'm thinking of installing a battery and external coil system still using the internal points and condenser. My question is how to keep the battery charged. Can I charge it using the lighting coil with some kind of rectifier? If so what type and how would the wiring go? Any help much appreciated.
