Hello, I also have a problem.
Overnight the power steering on my tractor stopped working.
I should add that nothing was welded on it.
But this morning, when I needed to fire up the ciapek, I plugged in the rectifier - some kind of electronic one and it shows me a charging voltage of 15,2 volts on it.
Surprisingly the power steering engaged, I disconnected the rectifier - the power steering works normally.
I turn the key off, turn it back on and the power steering doesn't work - I plug in the charger and the power steering works.
The alternator charges to 14.4 volts and will not switch on the booster, but when 15.2 volts are applied the booster works.
Where could the problem lie?
