7. Check spade connections on the starter relay for corrosion and poor connections. Check relay by unplugging the
spade terminal that goes to the starter solenoid and activate the starter button. The relay should have a small clicking
action (be sure the battery is connected and the key switch is on). If the relay chatters, check the voltage going to the
relay. Voltage should be a strong 12 volts from the battery. Then check to see if the relay is properly grounded. If a
problem still exists, replace the starter relay.
8. Inspect all wiring harnesses and cable assemblies to make sure there are no loose wires or connectors. Check that
all wires are secured away from moving parts, and that no wires are chafing against other components. Plugs, pins,
wires and other components may be replaced individually if necessary.
9. To check the voltage regulator for normal operation, monitor the voltage meter during a normal run-up of the helicopter.
If the regulator is working, a voltage jump will be noticed on the meter during the run-up procedure. If the meter does
not show a positive voltage charge, check the following:
A. Alternator switch is on.
B. Volt meter is working.
C. Water pump/alternator belt is on and turning.
D. Fuse is not blown on output side or field side.
If all of the procedures above are determined to be in normal operating condition, replace the voltage regulator. If a
problem still continues, it is possible the alternator is defective. See Note 14-10.
10. Check the alternator output with the helicopter in full operating condition and with the alternator switch on. The output
should be 13.5 to 15.0 volts, with a 16 volt maximum. If proper output cannot be achieved, the alternator will need to
be removed and serviced or repaired.
NOTE: This alternator is reworked at the factory to achieve our specifications and requirements. Replace only with a
RotorWay supplied part.
