Dual Motor Winches – IMPORTANT INFORMATION
Your dual motor winch will operate both motors when winching ‘in’ only. For winch ‘out’, only
the primary motor will operate.
Care must be taken not to change from winch ‘in’ to winch ‘out’ suddenly
as the
secondary motor will still be running forward with inertia whilst the primary motor will be in an
energised reverse state. Such a sudden change in direction can cause damage to the winch
which is not covered by warranty. Ensure your winch has completely stopped before
changing direction in operation.
Wiring - Dual Motor Winches (Please refer to below diagram)
NOTE:
It is recommended to always install battery isolator switches in series with your
winch. Dual motor winches can draw ~450 Amp per motor and isolator switches should be
rated for this at a minimum. Dual isolators are recommended, one per battery. Under high
load operations, the dual motors can pull up to 900 Amps. Due to the high amperage,
Sherpa 4x4 recommends wiring to dual batteries to spread the current draw.
