Atco De Luxe - dodgy coil?

Hello all!

I've just bought this non-running Atco De Luxe as a project. It's got a fair bit wrong with it, but first and most important is it won't produce a spark.

I've cleaned and gapped the points, checked all the wiring and replaced the spark plug. Still nothing. I'm getting a multimeter reading of 10k ohms from where the ht lead plugs into the coil and earth, and I've read this should be lower (3-5K?). Would this be enough to completely kill the spark?

Cheers!

Quite possibly. Has the

Quite possibly. Has the stator got a separate condenser or is it encapsulated within the coil?

You havn't mentioned the plug cap - to be safe, remove it and check for a spark off the end of the HT lead.

No spark off the HT lead

No spark off the HT lead either. I believe the condenser is integral. This is what I've got (ignore all the crud, that's all been cleaned since).

Thanks!

So long as the points are

So long as the points are truly clean and all fixings and grounds are tight  I think that you are fairly safe in assuming that it’s the coil.

I'm also a fan of the Atco De Luxe, having bought two projects last year ... a 14" and a 17". I'm gradually restoring them. With the 17", I wasn't getting a spark, which with the help of members here I pinned down to being a coil/condenser issue (I have the same type as yours). Once changed (and replacing the points for good measure, as they are not expensive), mine now roars into life with a good, strong spark. 

Best wishes,

Darren
