Ok here is what is confusing me....I have heard of the resistor wire going to the coil in the stock older mustang setup..When I check the voltage at this wire I get full battery voltage..If it had an inline resistor wouldn't it have a reduced voltage when I check it?.....However it seems like once the wire is under load then it puts out a reduced amount (eg...10.5 volts at the duraspark module)....I'm not concerned about voltage at the coil when the wires are hooked up because that is likely different for each brand of coil so I'm only measuring voltage with that unhooked. This is with the wires still hooked up to the coil.
