started. Disconnect the battery.
2. Remove AC output terminal box lid (mounted on generator
casing).
3. All terminal box connections are to be removed. (See appro-
priate circuit diagram.)
4. Remove all cables (also earth lead).
5. A check of the generator terminal box is made by means of a
multimeter to determine whether there is continuity between the
individual windings connections and ground.
If continuity is detected for any of the combinations, the generator must be sent to the factory for inspection and
repair. If this is not possible, the stator can be rewound by a qualified tradesperson/technician. Winding diagrams
can be obtained from Fischer Panda GmbH, Germany.
This test, unfortunately, is carried out at very low voltage (9V) when a normal multimeter is used. Therefore only
positive short circuits will be displayed. There is the possibility that a short circuit will occur in spite of a negative test
result (i.e. moisture). A reliable check can only be carried by using an essentially higher voltage (approx 500V). This
type of measuring instrument is normally only used by experts.
If in doubt an electrician must check the winding for a short circuit with an isolation meter.

In these terminal boxe there are the electrical connection points for the AC
generator. Here is also the bridge for the protective grounding of the genera-
tor. The cover may only be removed, if it is guaranteed that the generator
cannot be inadvertently started.
