Stay Charge
$397.95
Stay Charge, truck and trailer harness kit, part 8400
Stay Charge keeps the trailer battery charged from the tow vehicle, so the hydraulic jacks have power when you arrive. A trailer that sits between trips, or that runs its jacks repeatedly on setup, can flatten a battery quickly, and EQ Systems hydraulic pumps need real current.

Which kit to order
Part 8400 is the harness for both truck and trailer. Part 8427 is the harness for the tow vehicle with a quick connect jumper cable harness instead, with a 25 ft truck harness and 12 ft jumper cables. Order 8400 if you are wiring both vehicle and trailer, and 8427 if you want the jumper cable option.
Why battery condition matters on a hydraulic system
EQ Systems hydraulic pumps are not light loads: EQ Systems recommends load testing the battery, which should deliver a minimum of 150 amperes at a minimum of 10.5 VDC for at least 30 seconds, with the terminals kept tight and free of corrosion.
