Troubleshooting
6. Attach one end of the remaining cable to the negative
terminal (black color, or "N") of the booster battery,
and the other end to a bare metal surface on the frame of
your tractor AWAY FROM the battery compartment (do
not connect directly to negative post of dead battery).
Take care that clamps from one cable do not
inadvertently touch the clamps on the other cable. Do
not lean over the battery when making this connection.
7. The tractor with the discharged battery should now
start.
Reverse the jump starting procedure exactly to remove the
jumper cables. Then reinstall the vent caps and throw the
cloths away as they may have corrosive acid on them.
J^WARNING
Any procedure other than the above could result in: (1)
personal injury caused by electrolyte squirting out of
the battery vents, (2) personal injury or property
damage due to battery explosion, (3) damage to the
charging system of the booster vehicle or the
immobilized vehicle.
Do not attempt to jump start a vehicle having a frozen
battery because the battery may rupture or explode. If
a frozen battery is suspected, examine ail fill vents of
the battery. If ice can be seen or if the electrolyte fluid
cannot be seen, do not attempt to start with jumper
cables as long as the battery remains frozen.
