Garmin TR-1 Marine Instruments User Manual

Connections to the battery should be made last. Connect the ground side rst. Connect the black (-) wire to the negative (-) side of the
battery rst. Connect the orange (+) wire to the positive (+) side of the battery terminal. We prefer that the system is connected directly
to a battery, but if you are connecting to a terminal block or other source, the Gladiator needs a 40 amp supply. If the autopilot power is
taken from an accessory switch, be sure that the proper gauge of wire is used.
Do not be alarmed if the connections sparks when connected to the battery, you are charging a capacitor inside the unit.
Do not cut out or eliminate the fuse portion on your battery cable, it is there to protect your system and will void your warranty
if it is removed.
The Battery cable is 8’ long. If you need to lengthen the battery cable, do so by following the table below for the proper gauge
wire. Be sure to include the fuse holder when extending wire.
As with any hydraulic system, the air must be purged completely from All
Hydraulic lines, Helms, Cylinders, Gladiator pump and
Shadow Drive Valve in order for the system to work properly. Failure to bleed the system properly and completely, will cause the system
not to work properly. See your steering system’s owner’s manual for proper bleeding instructions. Treat the Gladiator pump as the lowest
helm while bleeding the system.
You can download bleeding directions for most helm types from the internet.
Disabling the Shadow Drive Valve using code 367 ( See page 32 on how to change the Parameters) will make bleeding the system
much easier. Be sure the Shadow Drive is enabled again when you are done with bleeding.
Be sure to check for leaks at all Hydraulic Fittings; Pump, Helm, Cylinder, and Shadow Drive Valve.
Refer to the helm manufacturers instructions for the recommended uid.
Recheck for leaks and check hydraulic uid levels after Sea Trial.
