This is what happend, the car was running but not great, pulled the plugs and cleaned and regaped them,then car would not start again, no fire to the plugs,opened distibutor, points were pited so put in a new set and condenser,still no fire, checked coil lead and no fire when cranking over,had another used coil put that in,still no fire from the coil lead, ok I figure It's no good ether. Called local volvo dealer,they said $500 for new one or I could put in a regular coil,bought a externaly mounted coil and spliced it into the old switch,got 12volts to the coil but nothing out of the neg side or the coil lead when cranking over. Where do I go from here,any help please.
