[QUOTE="kme, post: 14288, member: 113"] No, it isn`t mate. Basically, I was asking the same question both times......... disconnect the ring from the C.U, and seperate all the ends (2 of each P/N/E.) From your post, I understand your insulation readings P/N are 0.00. Which, as your meter is looking at Megohms, means "less than 10K ohms". It DOESN`T mean 0.00 ohms. So, do an "insulation test" with a low resistance meter (0-2000 ohms). You`ll either get a reading of the EXACT resistance on the circuit; or an over-range indication. If its over range, use a multimeter, which will bridge the "gap" in resistance measurement, from 2K-10K. Again, you`re taking a resitance between P & N, at ONE end of the ring, while the other end is completely "open-circuit". NOW do you know what I mean?? ?:| [/QUOTE]
