...will follow.

The hot wire setup to the plugs is different...they seem to be wired in series? The hot wire runs from plug to plug. I thought they were supposed to be individually powered? Like, one goes out, the rest stay lit?
The car is currently "trapped" in the garage, so my photography skills will be tested. There is a Dodge Ram 3500 waiting for the engine to be installed in the way, so I will have to do my best in the garage. It was so much better in the sun!

I will look around and see what remains of the original system. This is currently energized by the ignition switch.
I guess I will be buying a multimeter just to find the hungry line that is gobbling the juice, but it seems the draw must be coming from the glowplugs being energized, I can't imagine the radio having the capability of being turned up loud enough to kill the battery in a couple of hours, if it was even turned up!


Thanks! I will look into the glow system an report the findings. Maybe my heat gun can pick up a clue.
