Has Anyone Worked on Glowplug Card

[BigRix]

I've got a Glowplug card that has all functions except grounding the relay. I currently have a switch that grounds the relay and I just hold the switch till the light goes out and everything is peachy.

I planned to pull the card and trace some circuits but thought I would ask for advice first. My searches came up with only testing and replacing the card.

I expect there would be a transistor used to control this circuit.

Any help would be appreciated.

Here are some good posts about this. The second thread goes into detail about the repair I have done to the GP card after a ground fault short due to incorrect GP relay.

I think antennaclimber was refurb'ing them at one point. I got some used take offs floating around here.

Go to parts for sale. (antennaclimber) has a good deal on GP Cards.
