Busco entendido en capotas electricas

[josegonzalez]

Hola tengo un e30 cabrio que compre hace ya unos cuantos años y estoy intentando hacer funcionar la capota electrica.
He abierto la centralita del maletero y a traves de los 4 reles que lleva en ella activandolos manualmente he conseguido hacer funcionar todo y ajustar todas las varillas, no se si el problema que tengo esta en la centralita esta o es problema de algun fin de carrera, ahi ya me pierdo.
Os agradeceria que si alguno controla sobre este tema me iluminara.
Gracias amigos

Se trata de un mero problema de sincronización y de ajustar los microswitches que las activan ...

Me han pasado un manual en ingles de como se sincroniza todo pero mi ingles esta un poco oxidado, entiendo muchas cosas pero en alguna me estoy liando, os lo voy a compartir haber si entre todos podemos hacernos un manual en castellano.

If your power top is raised/lowered manually or your top motor is disconnected, the top must be realigned before it can be normally operated again. I've heard that dealers normally charge $500+ to do this. This procedure to realign the power top was posted to the e30cabrio list several years ago by Greg (original post).
Top motor re-sync procedure>>

To the left of the motor that controls the top (far right motor) there is a black control box that has (4) relays (coils). Check these (4) coils with a 12v tester for power with the ignition key on. If all of these have power then it is possible to get power to the micro switches. If these relays do not have power, then you'll need to either swap out the control box or troubleshoot the wire harness by doing some continuity checks.

The reason the top does not work is because there is no power to the micro-switches, I'll explain.

Power to the micro-switches is controlled by the lid motor lock mechanism. The lock mechanism is controlled manually by the allen wrench. When the lid is locked and the lid motor engaged the switches will have power (you'll notice that when you lock the lid, the lid motor assembly swings in and out slightly). When the lid is locked it swings the motor closer to the body of the car and completes the ground for the micro switch. The problem is, it is very difficult to get both the lid locked and the lid motor engaged. They must be done simultaneously. If you have power to the relays, here is how to get power to the micro-switches.

This is easier with two people....also make sure the ignition key is on

Disengage all the motors (unlock the lid mechanism, disengage the lid motor and the top motor)

Undue your top from the front window and push it up like your going to put the top down with the switch

These have to been done in this order.

Re-engage the top motor (far right) have someone slowly lift the back window until you can seat the top motor in.

Now the hard part...

You have to lock the lid mechanism with the allen wrench and engage the lid motor at the same time. It took me several tries at this. Try locking the lid half way, then pushing in the motor half way and play with it until the motor pops in and the lid locks at the same time.

If you were successful you can turn the micro switch adjustment screw (located to the left of the allen lid lock point). When you turn the adjustment screw you'll hear a click when the switch turns on or off, you'll have to listen carefully. If you don't hear a click then you have to disengage the lid motor and unlock and try again. If you do hear clicks while turning the adjustment screw, turn the screw all the way to the left and slowly turn to the right until you hear a click. Then test your top, does it work? If not turn the screw all the way to the right and slowly turn to the left until you hear a click. Then test your top again, it should work and may require further adjustment using this adjustment screw.

This is a difficult procedure to explain, but it is fairly easy to do yourself. The micro-switch will not get power if you are unable to lock the lid and engage the lid motor simultaneously. My dealer could not even do it. So it will take some playing around with until you get the feel for it. Once all the motors are engaged and there is power to the micro switches you just have to turn the lid micro switch to the position the tells the system the lid is down and locked. Then the top should operate normally.

Eso ya lo hize varias veces, eso es un reseteo de la capota para que la ecu detecte que todo esta ok.
El texto que puse en ingles que me pasaron es mucho mas complicado.
Gracias de todas formas

[klobuznik]

Efectivamente es un engorro hacerlo a distancia, pero yo que ya he traído a la vida unas pocas te aconsejo que no toques los tornillos de los microswitches bajo ningún concepto.

[josegonzalez]

Buenas, una pregunta que igual es muy tonta, el tema que pone en el manual de mover con la llave allen lo llevan todos los cabrio? Lo pregunto porque no encuentro ningun sitio donde meterla haber si solo lo van a tener los pre.
Gracias
