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.
7.
Install the power cartridge in the gun handle as de-
scribed under Power Cartridge Replacement.
