Hello everyone
I've done some measurement to the battery and the results are below:
1.battery connected, reachtruck on
between positive terminal of the battery and reachtruck body 20.3V and 0 Ohm
between negative terminal of the battery and reachtruck body 27.7V and 6.2 kOhm

2.battery disconnected, reachtruck off
between positive terminal of the battery and reachtruck body 0 V and 0 Ohm
between negative terminal of the battery and reachtruck body 0 V and 6.2 kOhm

Does anyone know if this is a normal situation? The reachtruck is functioning normal and no error appear.

Thank you
