I've been running a depth finder attached to my trolling motor for years and both have always been attached to two batteries in parallel without any problems. I recently changed TM's to a more powerful one with i-pilot and now I loose everything but the bottom every time I turn the troller on. I'll try your suggestion and re-wire my DF to the cranking battery to see if that fixes it. thx.
