Wolseley Magneto

Hi folks After spending a few hours re cutting valve seats and grinding in the valves I have tried to get my WD2 to go.

Unfortunately we have no spark at all despite trying the old trick of leaving the magneto in the airing cupboard for about 6 weeks. I have cleaned and reset the gap on the points and now reached the end of my knowledge of magnetos. So I turn to you guys for help.

Any ideas?

Any good 2nd hand magnetos around or shall spend loads of money on a recon ( not a good idea as all spent on xmas pressies.) Could any of you folks recommend a company who could have a look at it for me, by the way I am down south in Weymouth.

Thanks for your help.

Tim, Martyn Percy, he is in Wellingborough but worth the postage. His details can be found in Stationary Engine.

Hi Tim, where are you based. I am good at telling you what is wrong But I cannot always fix. What I can do is free!

I'm a real fan of aggressive points cleaning, as the oxygen in the points cover gets converted to ozone by the residual spark at the points as they open and this causes oxide to build up, as the points chamber is frequently badly ventilated. It appears as a whitish layer on the mating faces that is a very good insulator. It can be so even in texture and colour as to be easily mistaken for metal

No disrespect, of course, but did you just wipe them clean or vigorously clean them with a little bit of 400 grit (or higher) wet and dry paper moistened with paraffin or somesuch, trapped between the points under their own spring pressure, followed by cleaning off with meths and a clean cloth?

If not, it is well worth trying.

Have you bravely tried putting your shrinking finger over the end of the lead? Anything at all?

Are you certain the pick up on the coil is touching the brass strip in the cover?

Have you tried attaching a torch battery across the points and flicking them with a screwdriver? You ought to get a very weak spark from that and a whopping great one from 6 volts.

If the worst comes to the worst, I might have one to suit - but let's try every avenue first!

I agree with all this about cleaning the contact points, but my experience when I used to service voltage regulators was that even the cleanest of clean cloths can leave particles. Perhaps not so critical with maggies, but regulators had to be dead clean. My practice was to use a piece of hard shiny cardboard, followed with a final burnishing of the points, using a feeler gauge thicker than the gap setting, and applying finger pressure to close the points on the gauge.

I heartily endorse Kim's point about the brass strip in the coil cover (check for good contact at BOTH ends) and would add one other often overlooked area. One end of the coil is earthed through the coil clamp/screw. These latter are prone to corrosion and its always worth carefully removing and cleaning. If you have access to an ohmeter then check the resistance from the HT button on the coil to the earth tag. It should be around 5k+ or _ 2K. hth Roland
