Glowplugs Never Energize and Have You Ever What the Inside of a PCB Looks Like

[70deuce]

The push button is not “hot” unless the master is on. With the master on and while driving I suppose somehow the rely could become energized but like a starter solenoid how often does one of those energize by itself? Thinking outloud here but I don’t see this relay energizing without application of a positive 24 volts. When I hook up the “wait” light or install another indicator light near the push button switch it will be hooked up to the glow plug power side of the relay so if it does energize somehow or it doesn’t denergize when I release the button I will see the light and can take steps to correct the problem. I don’t see this as being a big problem but I sure could be missing something.

I used the ground too from the manual button. Safer than running the hot in my mind.

Are you working this through the box or separately. I ran it separately. Running it through the box and the existing system would be great.

This is run through the box through existing wire that runs from the engine connector to the glowplugs.

15 degrees out this morning. Held the switch in for 7 seconds for a start within 3 seconds of cranking. Love having complete control of the glowplugs.

Hi, do you by chance have a closeup pic of the cr-2700 board? One of my resisters burned out and I can't tell what size it was.
