8.7
Generator output voltage is too low
If the AC generated is too low, then the consumers should be disconnected, one after the other, in order to reduce
the load on the generator. Generally the problem is then solved. The frequency should be checked, if the output
voltage is correct after the consumers have been disconnected. Should this be above the prescribed generator idling
speed, it can be assumed that one or several condensers are defective.
8.7.1 Discharging the capacitors
ATTENTION!
Never work on the control box, if the generator is
running! Do not touch the capacitors contacts, see
“Safety first!” on Page 10.

1. Switch off the generator.
2. Remove the starter battery.
3. Open the AC-Control Box.
The capacitors are discharged by short fusing both
contacts. The contacts (Flat plug) can be bridged by
means of a screwdriver with an insulated handle (short-
circuit.
