Hi and thanks for your reply .
Thge car is a 1992 imported by us from Germany.
The problem accord when the car had been sitting in storage with an empty battery, I have checked the battery and replaced by a new one and the problems started.
The new battery is charging 13.65 Volts with idling engine. but as soon as you turn it of the battery is using power to an unknown source.
It drains in 2 days completely to dead.
The cluster does not work properly also anymore ,
gauges of
Econometer
Speed
temperture
and cruise control ( maybe because the speedometer is not working )

Please let me know if you have any ideas where to look

THX Again
Ben
