St Elmo's Fire
I replaced the coil wire in the SEL the other day, and tonight, on a test run, I opened the hood (it was dark out) and my ignition coil wire was ablaze with blue electrical glowing down it's entire length....My local parts place lists a spark plug wire set for $299
 What causes this in a new coil wire? or any coil wire for that matter. I also see some arcing between the coil bracket and the body of the car.

I dont know about the fire but I paid $175 for wires at the dealer so maybe they have them cheaper...

PanzerSD, apparently the coil is bad. Try replacing the coil (either swap a known good coil or buy a new one) before going to the expense of replacing all the ignition wires.

the new wire I had measured 6.5k resistance....cleaned up and re installed the old wire. even with it's bleeding energy is still better than that 6.5k wire.

Mercedes have solid core wires. The coil wire should read 0 ohms.

I thought MB wires were resistive and that's why we need the non resistive spark plugs? I don't know, just repeating what I've read many places. I would like to know for sure.

the lengths of wire themselves, are solid core, o ohm wires.
low resistance, high RFI The ends (the can be removed) are resistor ends, at 5K I believe. which makes the assembly less active in transmitting RFI (buzz in your speakers) testing ohms should be done as an assembly (2 ends and a wire) but you can test in pieces if you REALLY want to be sure..
