Carrier ignition electrics

is wound as a small coil about 1 inch long and 3/16 inch dia. It acts as an inductor to stop the current to the coil collapsing when the heavy load of the starter is engaged.

reading the other posts, leads me to believe the extra wire is to provide an alternative current path, as Lynn describes. ie It seems to be taking current FROM the switch TO the coil side of the resistor.

If all else fails, I would disconnect all accessories and leave the ignition, charging and starting circuits intact, then check through them as you have been doing.

Ajays in Katikati may be able to supply the correct 6V resistor

best luck

Gidday all,

Thanks for the replies. Yes, I reckon you are spot on with the resistor being the wrong type. I did some more measurements tonight with the voltmeter. With just the ignition switch on, the voltage is 6.1 volts on one side of the resistor and 1.63 volts on the coil side of the resistor.

When the inspection lamp switch is turned on (without the inspection light plugged in) the voltage on either side of the resistor is 5.87 volts and 5.45volts.

Somehow it still seems to drop down to 4.2 volts at the coil but I am unsure how.

As you all say I need to get the correct resistor and remove the little hotwire from the inspection lamp switch and that should do it.

I'll try Ajays Rob.

Thanks all for the help.

Heres some pics. The resistor is thewhite ceramic on the left side (close up)

Hi Lynn

Thanks for that. It is quite different from the one on my panel. I'll do some hunting and see what I can find.

Cheers

They come in various forms. You will see its on a board with the cutout.
these were fitted to all ford v8s with the football distributor.
I have seen them with a fuse only(and resistor of course)
The other thing you can do, is buy an adaptor, that allows you to fit a standard coil (6volt), that does away with the resistor.

...were also used on the ford tractors and such, they're pennies a pound through an after-market parts supplier.

With those 6 Volt systems, running a 4.5 Volt coil, make sure your regulator voltage setting is not set too high.. it's best set at around 7.3 Volts or so... Higher voltage = more current = more heat in that resistor.

My 1941 11d truck had one of the original Ford ceramic resistors and it got very hot , causing loss of voltage at the coil.. I reduced the regulator setting to about 7.3V ( it was up at about 8V ) and the problem was not as bad, although it did continue playing up to a degree and I never really solved it - despite trying a NOS coil and various resistors.

As Lynn said, some people use an adapter, do away with the 4.5 coil system and mount a 6v coil away from the distributor/motor altogether ....
