Been working on an old 2004 pantera 4 that I purchased. To my surprise there was not an onboard charger anywhere on the boat. It also has 4 batteries. One cranking then a 36 volt setup for the trolling motor. Purchased a new minnekota 4 bank to charge all the batteries and I can’t figure out a spot to mount it. There’s not much room at all. I’m hoping someone has come up with a solution. I looked for mounting bolts or screw holes where someone took off the charger before they sold me the boat but I can’t find anything showing any evidence of a charger. Weirdest thing. HELP
