Cheap magneto condenser repair
« on: June 08, 2017, 09:43:43 am »
Don't know whether these have been covered on the site before, so apologies if I'm repeating an old chestnut.
The usual problem with a magneto is a knackered condenser and the only way to resolve the problem in the past was to have it replaced. Because they are embedded in the windings, this job was invariably expensive. You can buy these little things that bolt onto the points carrier these days and with a little internal rewiring, you bypass the old knackered condenser and replace it with a tiny tiny electronic device.
I have no idea how good they are, but at about eighteen quid, I reckon they're worth trying. My brother is currently building a side-valve Norton from parts. He's bought an early fifties ES2 plunger frame and road holders, I've donated a 54 16H engine and a whole bunch of other side-valve Norton stuff, including a Lucas MO1 mag with a crap spark. He's not about to get this pile of bits running any time soon, but I'm sure he'll give one of these little EasyCap devices a go. http://brightsparkmagnetos.com/easycap/index.htm
Looking at them, I reckon they won't last as long as the original condensers because they don't look robust enough. I think even inside a magneto points cover, they'll succumb to the ravages of our British winters. But at that kind of price, if they work for a couple of years.... I think they're probably worth a punt.

I've had one, but they don't make it very clear that you still need to strip the mag down to it's armature and disconnect the failing capacitor (condenser for those used to valve wireless sets!) otherwise it can be a waste of time fitting it.
To me, it's too long-winded for a get-you-home fix but too short-term for a permanent fix.
My advice would be that unless it's on your only rideable bike and you need it, when the mag's apart send it off for a proper rewind and new cap to be fitted.
