Transformer (T1) – Begin Spec B, 50 Hz
Only
The transformer (see /Figure 7-8) is located on the
backside of the genset (see Figure 6-2 on Page
6-3). The transformer can be checked with an ohm-
meter. Isolate the transformer leads from the circuit
and measure the resistance between H1 - H2 pri-
mary winding. The primary should measure 440 to
540 ohms. Measure the resistance between X1 - X2
secondary winding. The secondary should mea-
sure 225 to 275 ohms. If an abnormal reading is
measured, replace the transformer.
