It must be something simple, but darn if I can figure it out.....recently installed a new oil/temp gauge. Started the car, but was getting some leakage from the connector so I switched it off and tightened the connector. Tried to restart it....no go...and it hasn't started since. Bought a tester to determine if plugs were getting spark......no spark. Started at the switch, ignition had power when on....went to where the white wire connects to the wire going into the Pertronix positive ground distributor....there was power...checked for power where black/white wire comes out of the Pertronix and connects to coil...with switch on and bumping the starter there is power of varying voltage.....checked for power at positive and neg poles of coil with the switch on...no power...bumped the starter....still no power...the coil is a new one I switched out when problem began....where do I go from here???
