i had TM issues, before knowing it was the TM I recently went from a 2 bank triton charger, to a 3 bank minn kota 330 d, replaced batteries and charger. now cranking battery wont hold charge, not even for a second. as soon as I trim the motor down, it doesn't have enough power to crank motor over. I didn't unhook anything from the cranking battery, just added the leads from the charger to the battery. battery checks good, and charges TM batteries like a dream.any idea on what might be causing the cranking battery to die In a matter of seconds. even when charging and I hit th trim the charger tells me its loosing voltage, and goes back into charging mode for that battery. any ideas or help is appreciated, thanks
