So I've been having some ignition problems. My 40 was running a bit rough and rather than just replacing the stock parts with more stock parts, I sprung for an Accuspark electronic ignition upgrade.
The first thing I discovered is that the ballast had been removed at some point in the past, which was probably why everything was wearing out much faster than expected.
So I replaced the distributor internals with the Accuspark ignitor, got a new rotor and cap and replaced the ignition coil and spark plugs with some with a bigger gap. I ran a new switched ignition wire to the ignition coil because the old one had a fair amount of resistance in it.
After doing all this, no spark. The guy who sold it to me took a look and said everything looks fine.
So I took it back to stock, no spark.
I've tested the following:
Fairly sure the ignition leads are OK. Should I also be disconnecting the condenser? I've tried it both with and without it.
What else can I test? The thing hasn't run in about two months and I'm starting to get antsy to drive something. The last time I took it to a sparkie I got charged $900 to replace the battery so I'm really keen to avoid going back.

I've tested the following:
- Putting a multimeter from the positive terminal on the ignition coil to the battery earth with the ignition switched on I'm getting around 12v.
- Putting it across the negative terminal and the battery earth I'm getting about 1v.
- Pulling a sparkplug out and resting it on the negative battery terminal while it's still plugged in gives no spark.
