2007 Tourmaster T-40 B front batteries What voltage/type???

[Burkejonathan]

What type of batteries do I need specifically up under the windshield in front of the generator on a TM T40 B??

I've installed 12 volt and the generator is fault code 29 now with these batteries...

Sort of an emergency as it's quite cold and need the generator. I can exchange them in the morning.

Any help is appreciated very, very much.

Thank you,

Jonathan
