1975 V8 auto. I can't get a spark at all. I have fuel. I've changed the cap, leads and plugs. I've tried new points and condenser, and both my spare powerspark units. The engine spins well on the starter. Strange things, I have 12 volts at the coil but when the engine is cranking the volts drop to about 4.5 and no spark at all. I've tried both ballasted and unballasted could with no results. Any ideas please? Getting very fed up with this it's been like this for weeks. I've had it for over 4 years and it's been OK til recently. Thanks.
