If I measure the voltage at the wire connector to the electric choke when it is not connected, it reads 12v ignition on. If I connect the wire and then measure the voltage at the choke male connector it's attached to, I only get 5.2 volts! If I take another ignition source of 12 volts from under the hood and do the same, there is only minimal drop! I understand that the choke is pulling current when connected but why the different reading? Does anyone know why?
I think the 12 volt choke supply comes from or via the CCC system on this car (1980 Californian) so is it to do with less amperage from the CCC than the battery? The choke does seem reluctant to open the choke butterfly on 5.2 volts.
