The ignition system on my Convert is very simple, 2 coils, 2 condensers and two sets of points.
At one stage I noticed a quantity of what looked like oil below the coils so I suspect I may have lost the oil out of one of the coils and now I have one cylinder cutting out.
I inspected the coils and see what looks like a couple of hairline cracks in the insulator, these are the original BM200C coils
I tried swapping the condensers around but I still have the same cylinder not firing,
I replaced plugs, filed and re-gapped the points.
I have a circuit through both coils to ground, around 10K Ohms from the resistor cap to chassis but I think the next step might be to purchase 2 new coils.
Any suggestions on what coils to order
Any upgrades to the points system, is there a solid state upgrade to the dual point system.
Is there a car type coil I could pick up at an auto wrecker?

YMMV, but for simplicity you should upgrade to a DYNA-III ignition. Once it is set accurately you can pretty much forget. Maybe an annual drop of oil to keep the stock advancer system free.
Match the ignition with new coils from MGCYCLE.
Ditch the stock, original metal spark plug caps.

Or go this route and you eliminate both the points and the mechanical advance. It also shuts down the coils if you stall the bike but leave the ignition on. Plus it has a rev limiter too.

Another good electronic option that offers full control with rev limiter etc is

If you can fit them in, the big blue Boschs work well.
No experience, but I've read coils from old VWs will work.
fwiw ymmv good luck

I went the Dyna III route for my 'vert even though there have been reports of failures. Fitting everything on a Convert is a little fiddly because of all the extra stuff needed for the hydraulics. I made some brackets and mounted the coils on the top tube of the frame--it's a tight fit. I had to move the voltage regulator to get the coils in, so I also upgraded the charging system with a Euromoto Duralast. The box went on the frame near the battery. Expensive, but so far, I'm glad I did it.

I think Charlie had the mic drop with the free oem coil offer. Stock coils in proper order are great and fitment is easy.
