Hello.
It´s about this NYK F25D470M - serial: 5Z0112.
It has´nt been used in about a year. Now i have got power back on the battery an fixed the bad connections and batt.cells.
But no activation of the main concactors. The lights and horn Works.
There is ligth i the first two LED´s on the CPU and the steering Works if i manual activate the contactor for EPS.
Sometimes when i turn the key it wrigths: "SW1 8 / SW2 C" in the display. But only sometimes.
I have read something about some back up battery, anybody know something about that??

Thanks - Uffe
