Mysterious Glow plug Problem..good dectective needed

[bpeters2]

So here is the situation. My 85 300td has been running great. I was monkeying (with ignition turned on) around with some wires to my frybrid (WVO) control panel and I shorted some wires (sparks flew). I'm not sure what wires got crossed but the only 2 power sources in that area are: 1)directly from battery and 2) from cigarette lighter wiring ("ignition on" power source). Anyway, this caused my WVO contol unit to sense that the ignition was turned off (it beeps at when when ignition goes off without purging), this indicates to me that the "ignition on" power source was interupted. This was followed by a mysterious lack of power to cigarette lighter wiring and radio. This is mysterious because if the fuse for circuit blows then the glove compartment lights also go out, but in this case the glove compartment lights WERE still working. The fuse was OK and power was mysteriously restored to the cigarette lighter and radio. Also, this whole time the glow plug indicator light started NOT coming on and the car won't start. I haven't had time to do a thorough diagnosis of the Glow plug system, but I can tell you this: 1)there is voltage >12v to relay, 2) relay is clicking on and off and voltage >12v is coming out of the relay to the glow plugs when relay is "on". I charged the battery up real good (thought that might be the problem) and heated it with a block heater and tried starting it tonight but no luck. BUT there was a development....the glow plug light began coming on. It would work for a few cycles and then it would stop coming on. Does this sound like a bad relay??

Does this add up to anything to any of you all. Sorry for the long story, the whole electrical short circuiting thing could be unrelated (as those circuits aren't connected to anything too critical to the cars functioning). Thanks for reading all this..please help.
