Boater Homing Question

I'm installing a electric winch on my trailer that requires 8ga wire from the truck battery. Can I make a extension to continue this wire back to the batteries to keep the refer running while on the road? Fused at 50A. Ya, I know - disconnect it when stopped. Some of the trailer places have some whiz bang built in a little sealed black box that I question the need for - 30 yrs ago I was all for "whiz bangs" ! :lol:
 
Dave,
On the C Dory 25, I used one of the pins on the 7 connector trailer plug for 12 volts to charge the C Dory batteries. I used # 10 wire, (both plus and neg). I had a plug just aft of the hitch, and a second plug in the anchor locker. So I had a connector section of about 10 feet from the trailer hitch to the perment boat wiring which was connected to the console. I had a diode in the circuit--which dropped the voltage by about half a volt and thus would not overcharge the battery in the C Dory. I also had a 30 amp fuse in line. The rig worked very well.

You could take off from the power point at the truck or on the trailer, and use smaller wire--fuse it, perhaps a diode and the connectors. Should keep the batteries up well.
 
Hi Dave,

That should work. I use a separate cord from the truck back to the boat batteries to keep them up while on the road. 10 ga wire, fused. Never felt warm, keeps the batteries topped up with the fridge running while driving.

I'd like to take credit for the idea, but I got it from Brent.

Best wishes,
Jim
 
Me too. I went from Captains Choice to Captains Cat (it will not do apostrophes like TugNuts will). Just PM Tyboo or Bill. All your previous posts will change to your new user name too.
