"BTW John, should there not be a dip in the amp meter when the ignition switch is turned on. "
YES INDEED THERE SHOULD BE and around 4 amps as I posted below IFFFFFFFFFFFFF all the correct conditions are met and in place and working as I described...
"I still suspect the coil because there is no movement in the built in amp meter with a full 6-volts to the input side of the coil."
HOWEVER even if the coil is good theres still no ammeter movement UNLESS the points are good and closed and NOT burned, pitted or carboned or oil or oxide coated!!!!!!!!!!!! Take the coils output (To distributor) terminal and dead ground it then see if the ammeter swings to - discharge when IGN is turned on??? That eliminates and by passes all my described conditions.
Place an ohm meter on the coils LV + and - Primary terminals. If it reads around 1.2 to 2 ohms the coils LV primary is intact, if it reads an OPEN circuit the coils LV Primary is bad/open.
Put a 6/12 test lamp on the coils input and with IGN on it should glow, place it on the output (to dist) and it should glow when points are open (UNLESS LV coil primary is bad/open) but go off when closed (Unless burned or pitted or coated or not fully closed)
Id suspect the points or condensor BEFORE THE COIL
HOWEVER the 2 or 3 tests I described above are so quick n easy to see if the coil is bad/open!!! And it may well be, get a test lamp and ohm meter out to find out if its open?????
