Hi Noam

Unfortunately no markings.

It looks like a 12v regulator rectifier with two yellow wires for the alternator and one black and one red wire (red to battery and black to earth....I guess!).

I was having problems with charging, I think this is why I bought the thing in the first place.

I think I might risk it and put it on the triumph for a second or two.

My existing Zenor seems not to be reducing the voltage sufficiently, with 15V going to a very small battery. It hasn't boiled the battery yet. However, with the lights off at full speed I get 15v, but with the lights on only 12v.

I will give it a go.

Regards

Pat

Hi Pat.

It sounds like what you got is a regulator rectifier for a one phaze alternator.
It should work instead of the Zener.

Good luck,
Noam.
