3JH5 alternator and display panel

[capbillh]

Twice now the engine on/off push button has seemed to slip under the waterproof membrane. First time I must have pushed it sideways but yesterday it did it by itself The panel was dead with no lights nor instrumentation . First time the engine would not start but the second time the engine continued to run but the stop button did not work. I played with the engine button and lights came on with tach registering .The stop button was active then..
It is the new style digital display and four push buttons.
Also, what is the new 125 amp Valeo alternator voltage setting?
