Bought my PA, it had 2 miles on it.
Dealer put it on a Battery Tender trickle charger, I picked it up the next day to take it home.
It had 14.1 volts showing on the screen (not running).
Dealer put it in transport mode.
Got it home 2 hours later and put it in the garage.
Went to start it up and it would not start.
Fuel pump would cycle, the screen went through the self diagnostics, showed 12.2 volts on the screen (not running).
It had 4 codes (I took a picture of them, but I erased them - oops).
Dealer told me to put it on a Battery Tender, I did.
After charging overnight it still only showed 13.6 volts (not running).
I put it on a regular motorcycle battery charger (Battery Tender) for a couple hours, it charged it up to 14.1 volts.
Ran the diagnostics, cleared the codes.
I started it, it fired up right.
2 of the codes came back, one was not really a code, it's the part number for the display screen.
It won't clear.
The other one was for a knock sensor.
II took it for a ride, it was working fine.
Got back from the ride, checked the codes, cleared them.
All of them cleared except for the part number for the display screen.
Rode it the next day for 30 miles, no issues.
Got home, parked it and let it sit for the next 6 days (snow).
No battery tender.
Fired it up, rode it for 10 miles.
Got home checked the codes, still had the part number for the display screen.
No other codes.
You really do have to have a fully charged battery for this bike.
One thing, it never had a check engine light on.
