I have a series C Comet, the battery is going flat even when switched off, I’ve taken a battery lead off and put an ameter in, with the switch off it is showing a discharge of 0.2 amps. If I pull the plug (single wire) that plugs in the back of the dynamo out, the ameter goes to 0.00. It is 6 volt + earth, Miller dynamo, I replaced the regulator years ago with a little black solid stat thing that people used to use, forget what it was called think it was 2 or 3 letters, K something? Any pointers would be much appreciated.

I think you are talking about a "Ktec" regulator. They were excellent for a while but mostly didn't last overly long before problems arose....

I used a Ktek regulator on my Fiat dynamo and it lasted a few years before it went pop. Ithought "That's OK, I can live with that", and fitted another one. It lasted a few minutes! Cheers, Stu.

I use one of these to disconnect my battery, but, unlike a switch, if you forget to connect it after starting the bike, it is harder to take care off without having to shut down and restart in front of an adoring crowd.

Thanks for all your advice, great help, any recommendations on which regulator to use? It’s a positive earth 6 volt miller.
