Batteries are just new.. Shut the 1270 off after 10 min of running while its cooling down. Shut it off and turned it back on. Fires up like a charm. What I did was if the 1270 is going nowhere. I turn off the whole lights. If I'm plowing. I'll turn on the front and rear lights. Are you sure it's not the front and rear fog lights that I'm using that's causing the alternator to not charge the battery??
