fitting a solid state rectifier to a classic bike

[@DylanFry-mm6bx]

Thank you for this film Derek, its helped me greatly . Its people like you. In sheds everywhere, that keep British know how alive .

What a great video! Thank you for the baseline explanation that will help me on so many different projects!

Love vid Derek love all the old school ways,thanks mate

[@allyg2510]

great video, very helpful thank you, one question does the rectifier have to be isolated from the frame ?

[@derekevans8266]

No it does not need to be insulated in fact it is better if it is attached to the frame as it can get warm and the frame acts a a heat sink, I have fitted them to an aluminium plate to absorb the heat.

Hiya Derek, hope you're keeping well and still pottering about. Spoke to you a good while back Derek about a little LE Velocette that I have. Having a few problems with the charging side on things, I'll wait to see if you reply before I go into it Derek, but I could do with a bit of help please. Alan.

[@AlanWilliams-e9e]

@@derekevans8266 Thank for getting back to me so quick Derek, much appreciated. I've had this bike for a good while now, built it from a basket case. I had a plate rectifier fitted when I first built it Derek, very simple wiring on the MK11 LE. They had a pair of AC ignition coils tucked behind the front engine cover originally. But they always went weak and were replaced by a Honda CD175 twin output DC coils mounted under the frame. So like I say I've had this a good while and on ignition only it showed a charge an the Ammeter , But it never charged with the lights on. Didn't really bother me that as I only used in in day light. Couple of days ago I decided, after watching you video on the solid state on, I put one on the bike. Same as before. I reckon the generator is faulty myself but not sure how to test the output from the generator with my multimetre? Ill try and send you a link to one on sale on ebay so you can see what they look like Derek.

[@AlanWilliams-e9e]

"velocette le flywheel & alternator plate." this is on ebay Derek, you can see two indentations where the ignition coils used to be. The other stuff on the front on this one isn't on mine. Basically I think on position one on the ignition switch it used one coil, the on position two with the lights in it throws the other two on??

a slip of the old tong I said regulator it is of course a rectifier.

Thankyou Dave very helpfull

great video A++++++ john

[@martinwade9421]

You can buy a solid-state rectifier/regulator for 6 volts. You can fit & forget and feed all the AC output straight in. That machine is a FB Cruiser 80, and was positive-earth when new. You can, of course, change it to neg.-earth.

THANK YOU

I thought the old Lucas 6v systems used 3 pairs of stator coils, 1 pair connected for lights-off use, then the other 2 connected through the light switch for lights-on use, so it's important to know which of your stator wires is which.

[@derekevans8266]

some were wired as two sets of three coils and some three sets of two coils these would have four wires coming out not three.
