Reversible Winch Motor

This circuit uses common SPST continuous-duty relays, and will work on any DC motor. SPDT relays can replace each pair of SPSTs. Each relay must be rated for MORE current than the motor's peak draw when stalled.

This shows the remote hot-switching the relays, but it could also be wired to ground-switch them.
