My 2014 Grizzly 700 has been in storage without a trickle charger on it for 2 years. (I know, I know...)
Yesterday I started it with a battery pack starter, then put the battery on a 2A charge overnight.
This morning I took it off the charger and there was no display. I put the charger back on it and when I turned the key on I saw ER 1. No gear displayed. When I pushed the starter button I got a grinding sound like the starter wasn't engaging. It started right up yesterday...
Google says that's an ECU malfunction.
It seems more likely that the battery just isn't holding a charge.
Lesson learned.
