buttons on each switch.
The battery must be installed with negative terminal attached to black ground wire.
Negative terminal is identified at the post by "NEG", "N" or "-". The positive terminal,
identified by "POS", "P" or "+", must be attached to the big red wire which goes to the
solenoid. All batteries are to be fully charged before installing.
Charge with 6 AMP charger until fully charged.
Refer to schematic for fuse location and replace fuse if blown. If fuse blows repeat-
edly, see an authorized service dealer to have the tractor's wire harness serviced.

bolt.

choke control.
