"1981 ranger fish play" 488 mercruiser help with 24v trolling motor conversion pics
ok gonna try to get as much info out there right now in hope of a quick way to get this in the water. boat had 12 volt trolling motor that wont turn. the motor in the head rusted when the previous owner put it in the lake with out a bilge plug. the after having in craned out parked it with no drainage. 5 years later i get it. motor froze. full of yuck. leaves mud terrible. i put in a mercruser 470 untell i open up the old one. installed alternator because downer motor also was mistreated and i just presume stator or regulator is bad. i beleave all the rest of the wiring is original. excluding the radio, depth finders, and the auto aerator panel down by the drivers right leg, and i added a float and bile straight to starter battery.
right now i have 2 batteries in front the pos of the front most bat is going to 1 on the switch and the positive of the other to 2. i have the ground on the neg of the of the for most battery. now this ground goes to the front. i presume straight to the top pin on trolling motor plug. finally the common wire from switch goes up front. then to the bottom right pin (clockwise from ground pin).
now i put switch on 2 and jump pos of for most batteries to neg of the other. walla 24 volt at pins on trolling motor plug.
now the light on the deck is brighter than when getting power from switch setting 1. the problem with this is i dont know what the deck switches do. there are 4 of them up there.
the first says 12 volt.???????
the second says deck light.
the third i know lifts and lowers out drive.
the forth is just on off.
my concern is when this is all hooked up for 12 volt there is no jumper wire and there is a isolator back at the starting battery with a pos wire leading up to the front of the boat and a ground also runs with it.
then when the ignition is on the front deck light comes on.
regardless of the switches up front being on or off.
given that when i hooked the front bat bank up for 24volt the light will get brighter when using 2 on battery switch... and when hooked up for 12volt with no jumper the ignition switch turns on the same light, i assume that it would bleed 24volt back into the ignition system and charging system of the starting motor if i was to connect the pos and neg running from the back to the front and connect them to either of the batteries???????
i hope i have been clear enough on the issue for one of you boat genius to help.
hope i get her in the water soon.
washing her down tomorrow. shes had like 4 washes and cleanings and still pulling out crap. such a shame!!!!
