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.
