Probably a newbie question and I did a search on the forum and couldn't find an answer. Working on a 2006 Ultra Classic flhtcui that had rough idle, missing and backfiring on the high end. Would also die at idle sometimes. Planning to replace fuel filter, fuel lines, spark plugs, plug wires and intake seal (and new Map sensor). Bike has 62k miles and I figured while I was in there I would replace all i could within a budget. While tearing down I considered replace the coil as well but was trying to test to see if it was faulty. Service Manual indicated secondary resistance @ 2500 to 3500 ohms. I'm testing from one terminal to the other as in attached pic and getting a reading of 6.3 ohms at setting of 20k. Again I'm a newbie but I think this is 6300 ohms which would be out of range for spec OR am I doing this all wrong.
