Carrier ignition electrics

[Big D]

Gidday,

Just out of interest I left the new resistor in place, removed the 'hotwire' and fitted the instrument panel back into place. I flicked the ignition switch on, applied full choke and turned the key and within a split second the engine fired into life. That would be the quickest it has ever started for me.

Voltage at the coil was 2.65volts on start up and then lowered to about 1.5 volts as the engine warmed up. I would have thought this would need to be higher for a 4.2 volt coil, but maybe not.

I'll try another resistor and keep monitoring things and see how that goes. I'll also try another voltmeter to make sure I am not getting false readings.


Cheers

Hi Darryl,

The volts at the resistor (and everywhere else!) should go up after the engine starts , not go down .. the gene should kick in and charge the battery at a nominal 7.4 volts or similar, depending on the regulator setting. Your volt readings make no sense ! Does the ammeter on the panel show a charge ?

Yes, a good idea to get another voltmeter and check it.

I know those 4.5 volt coils do behave strange.. I often had a almost dead flat battery and the motor would barely turn over... it would growl and just manage to get over a compression point... despite all of that, the motor would fire and start
