10. When the ignition key is released after start-
ing, it returns to a neutral position where it
directs current to circuit breakers (13) which
distribute current for the operation of forklift

General Starter Checks
If nothing happens when you turn the ignition key:
1. The 40 A circuit breaker may be open and
require replacement;
2. There may be a defect in the ignition switch,
ignition wiring, or starter solenoid;
3. Check the condition of the batteries as de-
scribed in paragraph 10.6.2. Clean the battery
posts and the connectors at each end of the
battery cables. Also check the ground cable
between the starter mounting bolt and the

4. Check for broken wires and damaged insula-
