24V Winch Circuits
IF THE IMAGE IS TOO SMALL, click it.
In the top arrangement, the Aux Battery will require an external charger, or a TOTALLY isolated additional alternator, or a -12VDC alternator.
In the bottom arrangement, the normal alternator (which is represented in the standard loads box) will charge the Aux Battery when the switches are set for charging, but NOT when set for winching.
It's possible to build the lower circuit to work with SPST continuous-duty (winch-style) relays, and to be changed instantly with a single switch. Or SPST battery-disconnect switches can be used, but for safety, they should be organized geometrically so that that the wrong pair can't be activated to cause a dead short across either battery.
