Turbine Alternator Removal - Graco 218-026 Instructions-Parts List Manual

Turbine Alternator Removal

1. Remove power cartridge from the gun handle as
described under Power Cartridge Replacement.
2. Carefully twist the turbine alternator (3a) counter-
clockwise and pull it off the power supply (5) until just
disengaged from the coupling. Then continue to
slowly pull the turbine alternator away from the
power supply, disconnecting the 3-wire connector
(HH). See Fig 19.
3. Using an ohmmeter, test the coil in the turbine alter-
nator (3a). Measure the resistance between the two
outer terminals of the 3-wire connector (HH). The re-
sistance should be 3–5 ohms. If the reading varies
from this value, replace the alternator.
4. Measure the resistance between each outer terminal
of the 3-wire connector (HH) and the turbine alterna-
tor housing. The resistance should be infinite. If the
resistance is not infinite, replace the alternator.
5. Partially connect the 3-wire connector (HH) onto the
prongs inside the power supply (5). See Fig 19. Us-
ing a small screwdriver, push the connector onto the
prongs until seated.
6. Slide the turbine alternator (3a) onto the power sup-
ply, being sure to align the coupling between the
power supply and the turbine alternator housing.
Then twist the turbine alternator clockwise to lock the
coupling.
