Hi guys, I'm new to Bantams, last one was a field bike when I was 14 years old 53 years ago!

Could anyone tell me the correct way to wire up one of these little square rectifier things, and should it be earthed to frame or not?

Bike has been converted to 12volt positive earth.

Just in case you don't have a rectifier with blade connectors (which is probably marked similarly anyway), any modern silicon bridge will be marked like this one:

Bridge.jpegWhich is pretty self explanatory, with a +, a - and two ~. The 2 ~ go to the generator and in your +ve earth case, the + goes to earth. If you have bought a metal cased bridge, just ensure that it is not assumed to be for -ve earth with an internal connection between - and case or you will have a direct short across the output!
