Thanks also for your input....the 12 volt charger I have used in the past is about 15-16 years old...it is an automatic type and can be set to output 10/2/50 amps.
Just be sure you plug it all the way in to the aux socket on the dash before you leave. The little center male pin really does have to touch the contact in the back of the aux socket, as my wife discovered a couple times:laughing:
Our charger/maintainers have indicator lights that show what is going on.
She'd come to the house and say "no lights on the charger" After a couple
hikes back to the barn in the snow with her to push the plug in a bit more and the lights come on, that problem was solved for her by the extra hike experience:thumbsup:
