The 12V battery on my 2019 Prime appears to be dead. Didn’t want to take a trickle charge. Followed the manual to boost it, but sparks seemed to fly and the horn went off. What gives?
Did you check electrolyte levels and battery polarity when hooking it up? You should be able to jump start it to get it down to an auto parts store to get the battery checked/tested. If you've been trickle charging it for years and never checked the electrolyte levels, all of it may have boiled out. The battery is due for replacement. Once the electrolyte gets below the plates, refilling may not bring it back.
