central locking

[Colin H F]

Hi again has any one got a wiring diagram for the central locking ( not remote locking ) as there seems to be more wires involved in the kits I have seen advertised. seeing as there are only 2 wires plus a ground wire and 1 wire plus a ground wire (passenger door)would I be right in assuming that the drivers door key when used operates a switch that is connected to the rod, that in turn sends a feed to the passenger door and operates a solenoid attached to the rod?

Hi Newbie,Dont have Bongo diagram but this might help to give you a rough idea how it works.

Cheers Malc

Hi Malc, your diagram shows the five wire cicuit which I believe to be remote locking, as explained mine is not remote just central . thanks all the same. Colin newbie

Hi Colin as I said its just a rough guide how Central locking works,do you have a Central locking control box.

Cheers Malc..

Hi Malc, If I have I dont know where or what it looks like, colin

I would start looking for the fault in one of two places; 1, do you get at least 10 volts coming off one of the pins in the connection block in side the door card (as in your previous posted picture on the left hand side.) using a multimeter??
2, check the wire loom between the door & body panel, they chafe & break. This could be why the drivers master lock don't operate the rest of the manual CL mechanism.

Here's what i did to mine to make sure the wires gave no more grief after a problem with the window electrics..
After repairing a snapped earth wire i simply took up the slack in the body panel & did away with the tie on the hinge that was putting undue stress on the wire loom.
I've had no trouble in two years!!

HI jaylee I have checked the pins and get a full 12 volts changeover on the two pins. I have also took the tape off where the wires go between door and cab and there are no breaks. the cables then go to a connector block which I cant get at and cross to the other side I dont know if there is anything inbetween but as stated there is no voltage presant at the passenger door. if it was just a matter of running another cable from A to B I would do this but I am not sure why there should be two wires being switched alternately when the door is opened and closed, Colin

surely there must be a mechanic or auto electrician out there who can show me how the CL works, newbie

This thread may help, I've never played with central locking but it makes sense from an electrical point of view (i.e. the output is pulsed in opposite directions ).

[Colin H F]

good point makes sense, to prove this I could run a wire from the pin on the drivers door across to the passenger door and touch it on each wire in turn and see if the passenger door locks & unlocks.

has any one any thoughts on this, Colin newbie

Mine has no central locking...only electrics are the front windows. I don't mind less to go wrong also a bit of exercise walking around the Bongo locking all the doors...

Have you checked the coordinating wire actually under the cowl/grommet that goes into the body work.?
I had to check twice, the wire break was well hidden due to the initial loom bending & twisting in a Vee formation.

It would certainly do no harm to give it a go!
However the question must be asked why don't your side door & tailgate CL work too?
Now this is just a layman's guess.. But i would investigate either fuse 4 (30amp) plus the connection behind the fuse board, a possibility of a relay fault (& i'm bugged if if know where it is) Or the aforementioned door loom wiring!
& trust me, the previous Japanese owner butchered the window switch in a desperate attempt to fix an intermittent fault, before i replaced it & found the dodgy earth wire in the loom on mine!

Hi Jaylee, I have proven the fuse in mine buy removing it and replacing it,it is the first fuse and it is a 10 amp as stated when I turn the key the voltage switches to the other one of the two pins but does not turn up at the passengers door,relating to the relay I have asked before where and what to look for I`m sure someone must know,but have had no response Colin .newbie

That would be right..! (I found this out whilst investigating the fitting of an auto window closure unit with my alarm/remote CL.)

Just been out & found it for you dude.!

PM sent! Security!!

just a recap on the central locking issue the connector block that has nothing plugged into, that I refered to in earlier post is definitely the block that the relay should be plugged into, I have just put my meter across the spades this morning and the voltage changes over when the door key is opened and shut so it looks like all I need now is the relay, unless it was taken out for some other reason
