Bongo Fury

Hi, need a bit of help with a central locking kit, had a kit fitted but it stopped working, control unit had no output to open it.
New one off ebay is a Big Hawks kit.
I have got the pos and neg
I know which wires on the van coming out the plug with 3 wires are constant live, live when unlocked and live when locked.
but instructions are rubbish and I can't work out which is which.
The old kit had pos and neg
1 x orange and 1 x orange and black to earth
1 x yellow to open signal
1 x yellow and black to close signal
1 white to locking motor
1 x white and black to other cl motor connection.
I have tried using same colours but no joy.
Any ideas anyone?

I see the dreaded scotchloks are being used. I've just sorted out a shedload of trouble on my towbar harness, caused by the installer using scotchloks. Didn't take long to solder connections instead and now I shouldn't have to worry about intermittent connections etc.

I know where you're coming from Mike, I am using them just to check all is working before I solder in permanently, I too have had bother with scotch locks, although I have had success with them too.

The first diagram refers to a "Central Lock Diagram" do you have that ? Otherwise its start measuring and seeing what each lead does with a meter and then a bit of carefull testing!

That makes a lot of sense. I used them (despite warnings from the experienced) on one or two of my early wiring jobs and in fact they've never given trouble. But after the shenanigans they caused to my towbar wiring (and car electrics - I suspect they were indirectly the cause of the o/s brake amp filament blowing every 6 months or so) I'm inclined not to use them any more for anything permanent. I cans see there might be times though when limited access make soldering impractical and scotchloks attractive. One slip with a soldering iron and you can b*gger your wiring insulation

There is no "Central lock diagram" it is usual Chinese instructions, I think that should say Central locking control wires as my last kit instructions said, but it does not tell me which controls which.
If I have a live feed into the control unit, is it just a case of putting the meter on each wire and seeing if it gives a + or - feed out when the remote is pressed?

If that was mine
I'd of thrown it over the fence
I hate electrics

Good luck

I would first try to search for a Central Locking system made by the company, if there is anything on the web it might have a diagram of there connections.
Failing that yes its check out each lead (make up a table and check record results) under all conditions also watch for pulses which are sometimes used rather than a continuous fixed condition. The careful checks is really to make sure that the leads that seem to be the ones you want can actually handle the current for the door solenoid and aren't just a lower current source that matches the conditions required! Also listen for any relays clicking but these days its likely to be FET's rather electromechanical!

Thanks Geoff, I'll have a go when it's light and report back.

Is this any help?

Thanks, but I found all those but the wiring colours are in different locations and the control box is different, I tried the colour coding to see if it was the same but no luck.
Unless my new control unit is dodgy of course. I will do the checks and report back.
