No Function when key set to RUN - Full Battery

We charged the Batterie for the lift last night. When finished I just checked the battery Display if it is full, all was fine. Full battery was displayed and the machien was ready to work.

Today I turn the key and no function at all anymore.
No light, no Sound, nothing happens. Not even a click from a Relais.

I checked voltage of Batterie: 49.8V idle
When I connect bat to charger, charger does not charge.


I checked with a multimeter the power in connectors without a battery connected. Result 100 kOhm with key in off Position and 200 Ohm with key in ON Position.

Any help is welcome.
Right now I wonder if the battery with load Drops voltage so that not even the electronics works. Is that possible?

Thanx for your help

I was wondering if the charger would start charging because of the low voltage, but I tried two charger and None of them even starts at all.

I will have to check the cells tomorrow.

Have you got a dead cell on the battery?

The voltage sounds low for a fully charged 48 volt battery.

A failed key switch or blown F60 fuse would stop the truck powering up but I would check the battery first.
