Connecting a Booster Battery
IMPORTANT: When connecting a booster battery
to the tractor battery(s), make sure the batteries are
the same voltage (i.e. 12 Volt) and the electrolyte is
at the correct level. DO NOT connect auxiliary
battery cables across the terminals of the starter.
Always start the engine from the operator's seat.
Procedure
DI98J017
STEP 1
Position the machine with the booster battery
next to the tractor so that the booster cables can
be connected easily. MAKE SURE THE
MACHINES ARE NOT TOUCHING.
STEP 2
Turn off all electrical components on both
machines.
STEP 3
Connect the booster battery positive (+) to the
tractor battery positive (+) and the negative (-)
to a good ground on the tractor frame, not to
the tractor battery terminal.
STEP 4
Start the engine of the machine with the booster
battery and run the engine for approximately 2
minutes.
STEP 5
Start the tractor engine. See correct procedure in
this manual.
STEP 6
When the tractor engine has started, disconnect
the negative booster cable from the tractor frame
and the booster battery negative first, then the
positive cable from the tractor battery and the
booster battery.
Auxiliary Battery Terminal (If Equipped)
Remove the red protection cap (1), from the
positive terminal (2); and connect the positive
(red) cable clamp from the auxiliary battery to the
terminal.
Connect the negative (black) cable clamp from
the auxiliary battery to a good ground on the
tractor frame.
MD03D108
Install the red protection cap on the positive
terminal after the starting operation has been
completed.
WARNING: Always connect the ground
cable last and disconnect the ground cable
first so you do not cause a spark at the
battery. A spark can cause a battery
explosion and cause injury.
