Can anyone tell me if this is part of the trolling motor system? THe trolling motor is a Tracker (Motorguide) beater from the factory.
Now I am suspecting it might be some old battery charger that ran off the cranking battery. If it's not related to the trolling system I want to remove it.
Two 12 gauge leads from this go to my starting battery, then it has what look like 14 or 16 gauge leads going to the trolling batterys.
Also, one of the heavy gauge negative cables goes from a trolling battery to this box, then out of the box (seen in pic) to the 4 way plug. That's why I thought it's part of the trolling system.
There is also a purple wire going up toward the fuse block.
