Bad coil? 2015 sportsman 570

While out riding I got a few 1268-3 codes that would immediately shut the machine down. It would restart fine every time and near the end of the ride I got a low voltage warning as well. I did some research last night and it seems that the code is normally thrown by a bad terminal connection or grounded wire.

Today I found a loose terminal connection (main positive) of the power distribution near the fuse box. I tightened everything up and went on to check the coil as well. The primary side of the coil is bang on spec but I could not get any resistance measurement from the secondary. Using the plug wire terminal to (-) as the manual states. I even tried resistance from the positive coil terminal.

Am I testing wrong? I tried every resistance setting I had on my multimeter. The machine runs excellent and I took it for a 30 minute test ride and no codes. Just looking for where I may have gone wrong (if I did). I want to make sure its good to go before I adventure to far.

The problem must be in your testing connections - if the coil secondary was open (infinite resistance) there would be no spark. Remove the plug wire from the coil and check minus terminal to plug wire socket - then check spark plug cap to coil terminal of the wire. Regardless of how you test it; if you have spark it has continuity.

You're just not getting a good connection with the meter. If you found the bad ground and its running good you've got it fixed.
