412 / Beaufighter wiring & wiring diagram

James

I had similar problems with my 603, which being of similar vintage may have
bits in common.

The volts to the indicator flasher unit go through the hazard light switch.
All connections to this and the innards need to be clean.

The volts to my headlamps go through the switch, this had been arcing and
the casing had melted. I purchased a replacement switch from BCL, then
subsequently found one at an autojumble for a couple of quid. The main beam
on mine goes through a 26 amp relay by the fuse panel but the switch on the
indicator stalk arcs so may be badly pitted, I always use the footswitch.

Drawings are on the Bristol Owners Club website.
