Alarm Controlled Central Locking - Help Needed

[Mike_H]

Hi Folks

I have fitted a well know alarm/immobiliser/central locking control to overcome "defunct" key fobs on our X reg Bongo - all works well until I come to fit the central locking.

System was working OK via Bongo fob (albeit with lots of sticky tape)

I have 4 options to attach the 6 wires coming out of the alarm...

1) 5 wire lock - +ve or -ve main line

2) 2 wire - central locking with lock switch

3) original built in where only a switch is installed in drivers door (a motor is reqd.)

4) N/A compressor driver

I have a 4 wire connector nearest the controller - Red, Green, Balck Earth, Blue/Brown 12v feed

If I lock the drivers door with the key it still triggers all the other doors to lock correctly.

Q - Can anyone please confirm what set-up I have (I though 1 first as there are 5 wires on the connector nearest the motor, but now think 2 due to connections nearest the controller)?

Q - If Ive wired anything up incorrectly have I "fried" the motor and/or the alarm controller? (I put the controller back to original set up and it now doesnt appear to work)

Q - Can I test the door switching/control by just "jumping" across the +ve or -ve to either of the green or red wires on teh connector nearest to the controller that I take to be the lock/unlock

Picy of instructions below - hope it can be read.

Does this thread help ? http://www.igmaynard.co.uk/bongo/forum/ ... al+locking

Thank Geoff - still none the wiser...Ive rigged up the "new" control as per method C in the diagram & I get 12v pulse on open/close function of the remote button, so I know the "new" unit is OK (worried I'd fried it!).

I have put the original system back inplace - ditto, all works & drives the other door's...phew at least I haven't hashed that up too.

I then tried to connect up the 2 "new" signal wires to the red & green that come out of the original controller (leaving them also attached to the original controller) to see if I can send the 12v pulse to the door motor that way - it pulses 12v on both wires across the meter but nothing happens at the motor, no sound or movement at all - so I am at a complete loss as to how to proceed...I hope I'm just having a particularly dim day and someone's going to "educate" me soon!

Trying a clearer picy...

I can't see how it will work if you leave the old controller in place, in fact its rather likely to blow a fuse!
When the door opener is doing nothing it Earths both sides of the solenoid for the two relays, then it takes one side or the other to +12volts to open/close, if you have left the old controller in position as well then the old controller will still be connecting both sides of the solenoid to earth.

dont try and meld the alarm and standard cdl system, just configure the alarm as a 2 wire and connect those 2 wires to the motor control wires in the drivers door. the alarm will then control the drivers door solenoid which in turn will control the vehicle locking, if that makes sense!

Thanks for the pointers guys - I managed to get a help line for the alarm manufactures/importers today they also advise you cannot combine the 2, so at least I'm not going completely round the twist!

Ive been advised to fit a separate 2 wire motor to push/pull the current lock actuator arm so I get drivers door controlled central locking - I'll try rigging up just the 2 wire method directly to the current motor to see what happens - if the fuse goes then I know its got to be a separate motor.

[321Away]

thats the point you already have a 2 wire motor in the drivers door and if your not using the factory fitted cdl system its not being used, so chop the 2 control wires going to it and use them, so according to ur diagrams, white/pink to +12v, black/white to ground, green and blue to the actuator as in bottom left diagram.

Ive tried every permutation I can muster of putting 12v feeds directly into the 5 wires coming directly from the motor....and still cannot make it work

Ive now had it further confirmed it cannot be done & I need a separate 2 wire motor - sound ludicrous as I'm staring straight at a motor in the door with and up & down (pretty sure that adds up to 2) wires, so sound like these clever electrickery geniuses/genii have made it as complex a possible...maybe its all to do with the flux capacitor and needs 1.21 gigawatts to make it work!

I surrender..off to buy a motor and cloths hanger and make the innards of the door look like a blue peter Xmas mobile

I'm sure as soon as Ive done this, someone will say "just twist the pink and the orange together, works every time"

what year car do you have? pretty sure from memory the control wires are blue,black and white and on a seperate cable from the drive wiring? if you dont go the seperate actuator route let me know and i'll go pull the panel off of a car in the line up.

The three actuators on the other doors are all two wire jobs, I'm surprised that they fit a 5 wire one on the drivers door when the remote is fitted rather than just use the same type.


If it is a 5 wire job have you tried the wiring version on your diagram that supported the 5 wire types ?

Hi guys - thanks for the ongoing help, much appreciated - its an X reg/2000

Ive ordered a motor from evilbay to see if this will help, but ideally want to use what's in the door already.

Coming from the door motor I have

Red
Red/Black

Both these 12v pulse via the original controller

Black
Gray/red
White/black

These look to send a signal to the other doors (cut them and only the driver door works)

Ive cut the 5 wires close to the motor and put a 12v pulse up the red & the red/black and nothing happens, but if i put one to earth and the other 12v feed the motor works & vs/versa - so sound like its switched to earth one open one way close...or Ive completely misunderstood the workings (very possible after 3 days of trying every method possible)

[g8dhe]

Thats how the actuator does work, one end goes to earth the other to +12v, if you connect the Red to the Green from your controller and then the Red/Black to the Blue from your controller then it should work, if it operates in the wrong direction then just reverse the two wires. You will still need to connect the Black & White from your controller to earth and the Pink & Orange to +12v.
The two relays in the controller simply reverse the connections to open / close the door when they receive a signal from the remote, the rest of the time they will earth both wires.

[Mike_H]

Just found out the alarm/cdl control only puts out 500ma so hence why it wont trigger the door motor - sounds like I could try to use a pair or relays...any ideas if this will work as although I get the concept of a 12v feed to both motor wires triggered via the relay how does each one in turn "become" the corresponding earth when switching lock/unlock??

[g8dhe]

Where did you come across the 500mA limit information ? It sounds a bit low ?
Also the diagrams they supplied hint that it already has relays for switching the power, hence the need to wire up three connections (Black/Green/Pink & White/Blue/Orange) for the opening and closing circuits.
