Put on new leads - still the same. Pulled a lead, plugged in a spark plug and have spark though not bright.
Put on a new HEI distributor cap with coil and rotor from new dizzy - ran great for about 5 seconds then died. Refused to start, so pulled a lead, plugged in a spark plug and have no spark??
Starting to run out of options. Can't find a capacitor near the dizzy.
Only thing left is this relay or whatever it is in the picture that has the power wire from the distributor going to it as well as other wires.

That looks like the horn relay

There is an inline fusable link near the starter.
As I rembember it it comes into play as you let go of the key in the start procedure
Worth looking at
Hot wire the engine and see if it runs

Ok I'd forgotten how heavy these are. It's got a Accel HEI Cap with Super Coil and leads, the coil provides the HT directly via cap and leads to the plugs. On the outside there is a 5pin connector, one is power, three are from a connector wired into the base. The three wires come from the Electronic Module screwed into the base, it has another connector which wires to the Hall Effect Module (under rotor) which is the electronic equivalent of the old points. On the base plate should be a Capacitor.
The following could be suspect.
1. Capacitor.
2. Hall effect pick up.
3. Ignition module
4. Main HT Coil
Also the 12v supply could be intermittent. I cant think what the fifth (5) wire is - maybe Tacho ???
Get a metre to see if the 12v to the dizzy fails. We need to isolate each bit untill we get it.
