Chim won't start....

[EggsBenedict]

Trying to get the Chim going again. Been about 5 years since I drove her properly - kids/house project/life in general in the way. So as it was nice enough today, thought I get the car out and start the cleaning process. No luck.

Cranks, fuel pump whirrs, but seemingly no spark from coil.

2.5Ohm across primary, 7KOhm across 2ndary - can anyone tell me if that's OK?

Other than that, I'm a bit stumped - can anyone tell me what I should be testing other than the coil?

I think I should be testing that the coil's got 12V on the input side, but not 100% on the circumstances (e.g what should happen with just key at ignition position, what should happen when cranking?). Unfortunately most car books still in storage, so bit helpless .

Key at ignition on position and you should see battery voltage at the coil positive terminal, check this first.

Just to add.
Measure between coil positive and a good engine earth. Also make this same measurement during cranking to confirm it has not dropped out are gone to a very low voltage.

Unplug the ignition amp, then ground the negative side of the coil, and the coil should crack as it produces a spark. If this work , your problem is the ignition amp, or the trigger head in the dizzy. Bit on testing the trigger head here:

Thanks Chaps - good pointers. Will have a crack at the weekend and see.
