Ford V8 ignition resistor question

[Big D]

Gidday Bruce,

I don’t know whether this will help but I had a similar problem with my Willys jeep which is on 6 volts. I’m with everyone else in thinking that it is the coil that is the cause of your problems.

My jeep used to start fine from cold but after about 30-40 minutes of useage it would just die. It would not restart unless I left the engine to cool for at least an hour. When the engine died I found that there was either no spark at the plugs or it would be an extremely weak spark.

What I did was to gradually go through the ignition system and replace a piece at a time in this order; plugs; points; rotor, condenser and then finally the coil.

What I never got around to trying was a suggestion from someone else in having a plastic bottle of water to squirt on the sides of the coil to cool it down quickly when hot, just so that we could immediately pinpoint that it was indeed the problem.

In the end I replaced the coil before trying this and the jeep hasn’t missed a beat since.

The bottle of water might be worth a go when it happens.

Cheers

Darryl
