Usually controller controls the contactor 0 wire, so if you backprobe the master terminal on controller, and install temporary test wire, you can test if the wires are okay, in case the contactor works(tested) and wires have beem tested, it's ost probably a bad controller.
Hello and thank you very much for answering.
There are two contactors, both work fine when removed.
One (50438766) for the hydraulic pump, it is not switched on: A1 = 24 volts, A2 = 6 volts (only wire disconnected, otherwise 24 volts).
The other (51296863) for the electric motor, it is not switched on: A1 = 24 volts, A2 = 5 volts (only wire disconnected, otherwise 24 volts).
24 volts is present on the contactors just after turning the key.
The two contactors can be engaged when I connect A2 to 0 volts (with A2 wire disconnected).
the hydraulic pump is working.
the electric motor has resistances of 0.4/0.4/0.5
nothing happens when forcing the contactor of the electric motor.
Only the horn works
What can I check?
Thanks in advance
code means the Contactor is closed instead of open or....contactor is open instead of closed.
