bad starting '71 A65

[rhyatt]

These plug caps are such innocent things but get overlooked in diagnosing running and starting.
I'm helping a pal with his Japanese 4 cylinder currently, with the long ngk caps.
2 outers were completely open circuit with my meter and 2 inners were really intermittent with circuit.
They were meant to be 5k and for 6 or 7 quid each sorted.
The spark had been a feeble yellowy orange and not a healthy blue crack.
And they're so simple to check.
If your multimeter is self-ranging all the better but if you have to select scales then try bigger and bigger ohms scales until you have reached the highest.

Thanks Rhyatt, yes I discovered how to measure the resistance during the process of figuring this out. Good old Mr Google! Good that you've spelt it out here though for those that don't know.
Cheers Glenn
