5. The switch wire that connects to the solenoid
should be at least 12-gauge (Figure 4). For
alternative wiring to incorporate the factory remote
solenoid, See Figure 5.
Note: If your original starter had wire going to a
second terminal, an ‘R’ terminal, this can
generally be bypassed. See the information
on the last page of the instructions for more
details.
6. Attach the battery cable. The gauge of the battery
cable depends on its length. Using the proper
gauge wire is important to the operation of the
starter. Both the positive and ground wires must
be able to meet the demands of the starter. The
chart in Figure 5 shows the recommended sizes.
Be sure to route the wire away from the exhaust
and moving parts of the engine.
7. Connect the battery terminals and start the engine.
IMPORTANT: Never operate a starter for more than 30 seconds at a time without letting it cool for at
least two minutes.
