Carrier ignition electrics

Gidday all,

Thanks for the replies. I actually acquired an ‘official’ 6 volt resistor today and fitted it into the system.

Interestingly this time, the voltage at the coil side of the resistor was 2.6 volts – up from the 1.9 volts with the previous resistor. The voltage on the other side of the resistor is 6.4 volts.

It also measures 2.6 volts at the coil with this resistor in place.

Not the 4.2 volts I would have expected though with the change in resistor.

Adding in the ‘hotwire’ back in from the inspection lamp switch brings the voltage back up to 4.2 volts at the coil. Strange!

I guess it is possible this resistor that I put in is faulty and it has stepped the voltage down too far.

I should have another resistor to try by the weekend, to confirm one way or the other.

Mike – I’m interested in the voltage regulator setting you mentioned. If that was wrong, would that not affect the voltage going into the resistor?

Like you say, fitting the 6 volt coil might save me time in the end but I’m at the point now where I’d like to find out the cause of this.

Cheers
Darryl
