hooking up 24volt on Yar craft 1785

[cvanderweyst]

I recently purchased a 1785bt and I am not quite sure how to hook it up 24volt. It has factory wiring with two sets of pos. and neg. cables labeled battery one and battery two. Do I use one set of cables and link the batteries together or do i hook up each battery individually.

I called two diffrent service centers and they each told me something diffrent.

Not a service mechanic here but I'm going with the factory wiring option. Obviously, the manufacturer built the thing to accommodate wiring to each battery individually. So why not do it?

Good Fishing,

but then if it is only running 12 volts to my 24 volt motor it can cause damage

Before you connect your trolling motor check to see what voltage you have at the plug. It is way better to be safe then sorry.

It sure sounds like Yarcraft set it up for a easy setup be you can't be sure it is for 24 volts because it sounds like a 12 volt setup because you usually have to connect the positive from one battery to the negative of the other battery and then you would take the cables and connect to the posts that are open and then you would have a 24 volt setup. You would only be using the set labeled battery 1. The other thing that you have to watch out for is one of those cables more then likely will feed the rest of your electronics so you will want to check then voltage at the fuse panel when you do get it set up. You could hook up battery 1 and see what you have for voltage everywhere and then hook up battery 2 and do the same. Hopefully one is for your trolling motor and the other is for your electronics.

When in doubt check with a multimeter. If you don't have one you can get one at Sears or almost any automotive section for around $10.00 and you will find it is a CHEAP investment.

It's likely converted to 24V at the plug, but I'd check and double check with a multimeter prior to frying anything.

Definately wire it at the plug. Run all 4 leads to the plug and make 24 volts at the plug. If your plug is not able to do so get a ranger factory plug setup, usually can get them at cab elas. This way you won't have to mess around with a jumper wire when you want to charge. All ranger boats come this way for a reason. Make sure you are running heavy duty wire. can't go wrong with 6 gauge.

I figured it out when i went to the dealer to get the 4 prong round plug, when you hook up the plug one way it is 12 volt and the other way 24 volt

(it has the jumper wire built in).It also says on the dash panel above the plug in that the "black plug is for the trolling motor" and the "red plug is for the charger" does this mean i can charge the batteries by plugging a diffrent cord into my boat?

I just baught an onboard charger today (because the batteries would be difficult to get at to charge) But it is still in the box and i could return it if i can charge via the 4prong plug.

The boat is factory wired with heavy cable already. The trooler batteries go under a floor panel mid way up the boat and are wire to a dash terminal in the front and back. (dash term. has 4prong plug, battery meter, and a switch to test each battery)

I believe what they are trying to say is you can hook up a battery charger to the red plug and it will charge both batteries at a 12 volt rate. This way it is much easier for you to charge them with out having to get in the boat and open up the floor. To be sure you might want to ask this in the Boat & Motor forum or call a dealer and see what they say.
