b. Test Results
If the correct voltage is obtained, everything is
good up to this point and the problem would have
to be in another area.
If you do not receive the correct measurements,
the problem may be in the wires, connectors, or
transformer. The transformer is located in the rear
of the base under the stainless steel base cover.
The stainless steel cover will have to be discon-
nected and lifted from the base for access to the
transformer for further testing.
c. Capacitor / Rectifier Unit Test
1. Make sure all connectors are connected,
connect the power cord and turn AC120V operation
ON. Test connectors HN2 and HN3 using a voltme-
ter. See figure 5-5.
5-5. Capacitor / Rectifier / AC120V Transformer
The Capacitor / Rectifier Unit contains the battery
charging system as well as the components for
AC120V operation (except the transformer).
a. Transformer Test
1. Confirm 120VAC input at HN1 using Main
Switch test in 5-3a.
2. Connect HN1, disconnect HN2 (brown and
red wires) and using an AC voltmeter, test the
transformer output at HN2. See figure 5-4.
3. Meter should read 22VAC.

Figure 5-5. Connector HN3
2. Test connector HN2 at pins 1 (red) and 3
(brown). Meter should read AC23V.
3. Test connector HN3 at pins 1 (purple) and 2
(black, ground). Meter should read DC30V.
4. Test connector HN3 at pins 5 (orange) and
2 (black, ground). Meter should read DC27V.
