First I would not call 12.7 fully charged. should be 13.2 at a minimum. I would check your charger and or alternators . Second make sure you have a ground wire coming off each battery going to the block. Not just a jumper black wire going from one neg terminal to the other neg terminal then to the block.

Just commenting on what endeavor1 had "originally" with ground from engine to engine and back to one battery. Personally I've always had each engine ground to battery with a strap between engines as well as battery to battery. Grounds can be troublesome leading to failures on who knows what.

I hate grounds!!! They always seem to cause me the most issues and are tough to track down. Over the years I'm getting better though. Ohm meters are my friend along with a wire wheel to clean up contact areas

I love them, much more cost efficient than replacing expensive components!

Are these 500s still turning belt driven air cleaners? When I had M3s on my 500s if the battery was in any way down or bad connection it did the same. To be honest, I bought a spool of OO gauge wire this winter and built new cables. My BT was originally setup with a shared ground between the engines then back to 1 battery. Now both motors go to an individual battery. It made a difference.
