2016 Iron. I get a spark when I disconnect the Battery.It is more than I can measure on My Meter. How much is normal when I get an ammeter to measure correctly. This is the heavy cable that is sparking. It kills the Battery in a couple of days.
Thanks Steve

Since your ECM is always powered (and maybe alarm, etc.), you would expect some kind of spark when you disconnect battery. That's normal.

If your battery is draining, that is a separate issue. You can try pulling fuses to see which system is drawing power.
