Is there a resistance that a bad wire will show? All my current plug wires show the same exact resistance except for one, which shows a really high number. It is the coil to distributor wire. The four other wires are showing the same resistance. I have an 86 190e 2.3-16. Any suggestions as to which set of plug wires work the best? The ones I took off were an aftermarket set. I reinstalled a Bosch OE set that I had on the car for about 30000 miles before i changed it to the aftermarket set. I bought this set from Bekkers.
Thanks, Joe

Since the real OE wires are just that, solid stranded wire, there isn't any resistance drop like American cars. But the spark plug ends are the resistors. There have been 3 different values over the years 1K, 2K, & 5K ohms. At the coil there is usually a 1K ohm resistor. Most of the Bosch aftermarket stuff is Stranded cloth like american junk. The wires (OE copper) themselves rarely go bad but the resistor ends fail & can be replaced by themselves. Beru replacements are OE quality with solid core wires unlike Bosch(even at dealer).
