85 ezgo quits after half mile
 

Son drug home a 1985 ezgo gas. We fixed the driven clutch, but it would die after running a while and would have no spark. I tried switching to HEI ignition, but had no luck. Had it wired wrong. After giving up on that, I went back to the original setup, but had no fire at all. Traced it to the pulser, so i replaced that. It fired right up and runs great. We can run it forever, if we keep going, but if we stop for a while, it doesn't have spark again. Let it set for half an hour and it runs again. I would like to try the HEI again, but am having trouble finding a diagram for a 2 PG engine. Is the diagram the same for the 3Pg engine?
Any suggestions what to try when it has no spark?

The only difference is that yours doesn't have the extra neutral safety switch.

There is also another variable. All HEI modules are not created the same. That means you have to switch the red, and blue wires from the pulsar to see which way runs the best.

You can use this 85 manual to compare diagrams.

I have tried 2 different Hei units wired as shown on the 3pg detail. Blue and red from the pulser to W and O respectively, (have switched them and still no fire) C has a black wire from D- on the voltage regulator and B goes to the orange wire on the coil. This will not fire the coil. What am i missing?

If i switch the pulser wires back to the original setup, it will run till it warms up, then will not fire. That is why i would like to switch to the Hei unit.

C goes to the negative side of the coil. The black wire going to ground on the voltage regulator should be going to the mounting holes in the module.
B goes to the positive side of the solenoid, or the ignition coil. Doesn't matter they both converge at the solenoid.

You should have 5 wires.

Wiring it correctly worked. Thank you
I left the blue and red hooked up the way it is in the 3pg diagram. Started right up and runs good. Went about a mile, stopped, let it set for a while and it started right off.

Thanks again

Glad to hear that it worked.
