Bonjour, je donne des nouvelles
j'ai toujours l'erreur E 0102
J'arrive a avoir 3 nivaux de sonorité avec le klaxon
faible : l'un des 2 contacteurs n'est pas dans la bonne position
moyen : les 2 contacteurs sont dans la mauvaise position
fort : klaxon (fonctionnel avec le bouton)
le contrôleur fournit toujours du 24v sur le A2 des 2 contacteurs (jamais 0v pour l'enclencher), le A1 est toujours alimenté en 24v.
Après avoir tourné la clef, le klaxon est faible, il s'arrête en déclenchant le relais de puissance 24v pour le contrôleur.
en suivant le conseil de "Chadly" j'ai modifier pour que le contacteur s'enclenche en tournant la clef mais sans résultat.
Que puis-je faire ou contrôler?
La batterie n'a pas été entretenue (éléments a 0v, vis cassées dans les éléments,...) , donc j'utilise une alimentation 24v 20A suffisante pour la pompe hydraulique.
Peut-il être en cause?

Hello, I am giving news
I still get error E 0102
I manage to have 3 levels of sound with the horn
low: one of the 2 contactors is not in the correct position
medium: the 2 switches are in the wrong position
loud: horn (functional with the button)
the controller always provides 24v on the A2 of the 2 contactors (never 0v to switch it on), the A1 is always supplied with 24v.
After turning the key, the horn is weak, it stops triggering the 24v power relay for the controller.
following the advice of "Chadly" I modified so that the contactor engages by turning the key but without result.
What can I do or control?
The battery has not been maintained (elements has 0v screws, broken in the elements,...), so I use a 24v 20A power supply sufficient for the hydraulic pump.
Could it be involved?
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.
