Hey Guys,
I'm having some ignition trouble. Car cranks fine ,but no spark. I have power from the coil,but none from the dizzy to plugs.
The only thing I can figure is the Accuspark electronic ignition,I have. Has anyone else had trouble with these.

I did. Installed the unit and like you, no spark. Spoke to the rep in the UK and sent them pictures of my wiring. They had no idea but sent me another unit. I had the same issue until... I moved the Accuspark unit closer to the pickup ring. If the gap is too big it won't trigger.
Try that...

If you are getting a spark from the coil (centre HT wire) the ignition is OK, the problem must be with your Distributor cap, Rotor or plug wires.

It was working fine, until one morning. Of course, I went ahead and changed out everything else,. Ill give it a go.

Have you put in a new condenser? I posted about a similar issue and had a ton of suggestions for new condenser and/or new points.

He is using electronic ignition.

Please clarify!

Yes ,the accuspark eliminates the points and condenser. Yes. I tested the coil, even swapped it out for one I know is ok
The rotor spins, but still just cranking.

If you disconnect the centre HT wire from the distributor and hold the end close to a good ground, do you get a spark when cranking?

I had an issue with my accuspark, during races I was getting a weird intermittent thing. Found my module wasn’t screwed down. Screwed it down and all was good. Later in race season I was having the engine mysteriously cut out. So I’d be wizzing around and have to turn my ignition key to get it running again. That time i found one of the wires coming from the unit was shorting out. I had my car running, I’d gently twist one of the wires and the engine cut out. I replaced as much of it as I could and all was good again.

I picked up a cheap inline spark plug tester. Cranked it but no spark. Should I trust it. Ive tried two different coils, but no dice! The auucspark wiring is very simple.
red to positive ,black to negative. whats confusing ,is the rotor spins.

might you have the old points and condenser to try out? not that hard to swap, see if its the accuspark unit that's the problem. but trying a different rotor would be an even easier test as well. I'd listen to tony though and test the main lead for spark.

The rotor is on a shaft driven by the engine crankshaft. All it does is direct the HT current to each HT plug wire in the cap in sequence.

Rotor arms can wear at the contact or short to ground by forming a carbon trail (tracking) the same thing can happen with distributor caps which can also crack.

How to test a coil:

Disconnect all the wires.

Take a 12v + direct from the battery to the + terminal on the coil.

Make and break the - terminal to ground with a short wire.

Each time you break connection with the ground you should be able to see a spark with your spark tester from the HT cable on the coil.

Which version is the accuspark in this car?

Is it the self contained or is it an external box with the dizzy housing only the sensor?
