A3.1 Checking the power draw of the brushes Up/Down actuator
1
Move the machine to flat, dry flooring.
2
Make sure that there is enough room around the machine to perform the dismantling operations safely.
3
Remove the top cover of the machine and locate the connector of the actuator.
4
Separate the connector of the actuator from the main wiring loom.
5
Locate the in-line fuse-holder connected to the black wire, unscrew it and take out the F5 fuse.
6
Use a digital multimeter and select “Continuity” mode.
7
Position the red probe on one end of the fuse, the black probe on the other end and check that the multimeter
emits a continuous sound.
7a
If there is no sound from the multimeter, then the fuse is broken (burnt out) and must be replaced.
7b
If the multimeter emits a continuous beep, this means that the fuse is sound; accordingly, proceed to check the
power draw.
8
Make sure that the batteries on the machine are charged (12 V ± 1 V).
9
Use a clamp-on ammeter with a full scale reading of at least 200 A (amperes).
