Is there an update to this issue? I am very interested in knowing what the root cause was.

Have you checked the dwell? Maybe the points are not closing (no build up of electrical field, hence no spark). You'll need a dwell meter to be 100% sure

As Jeff mentioned, if you own a car as old as ours are, you need a test lamp and volt/ohm meter. Listen to Jeff

Harbor Freight gives voltage meters away every now and then with their coupons. They sell test lamps too...I've used mine many times, mostly to debug a tail light or headlight issue. Another nice thing to own is a "spark indicator", These little devices, connect inline with your plug wires and all you to see the existence of spark with out disconnecting and grounding the wires. Very handy and keeps your hands free.

Don't know if they have HF in the UK.

There is a retail chain similar to Harbor Freight (inexpensive tools) in the UK. I can't recall the name off hand.

Hello

I have found that people who change the points make the mistake of grounding the points wire when it should be on the insulator. This sounds like a classic case.....

Check that the contacts wire is not to ground, look up the correct way to assemble....

You will be running in no time.

Kind regards

Hi all sorry for the late reply i havnt been able to work on it till lastnight. But found the problem!! Turns out that the wire from the coil to the dissy cap wasnt soldered! So loose wire was touching the body off distributor and no spark. So most of you called it! Thanks alot for all your help much appreciated everyone! Great communitysmiling smiley

Knew it would be something stupid
