Battery voltage, switches and cut out

[Peter Naulls]

Hi Charles, and Derek,

Thanks for your thoughts, but no, it has halogen bulbs in the headlights. The charging system works fine.

I know it's not an earthing problem because if I connect a lead from the earth terminal of the battery to the earth wire at the tail lamp it doesn't make any difference. If however I connect a lead from the supply side of the battery to the supply wire of the lamp it cures the problem.

Peter.
