John,The coil + will only get voltage from the MSD when the MSD box gets a trigger from the dist.or crank trigger.Don't check for voltage at the coil it's going to be 400 volts or more when cranking.You should have 12 volts all the time at the big red wire and 12 volts at the small red wire with the ign.switch on.Bill.
