Wiring Diagram for 1995 Chimaera

[smb]

Guys, does anyone have a wiring diagram for a 95 Chimaera please, I've check the one in Steve's bible but the area around the central locking relay etc is wrong as it's for an earlier car. Has anyone ever managed to get a diagram?

thanks

I've just been looking at that diagram myself, and I don't think it's correct for my 94 Chim either. I would also be interested if anybody has any additional wiring diags. The one in the bible doesn't show any gauges either (e.g. tacho/speedo).

That is the only one I have come across!

[the dodger]

I guessed that Steve. Wonder if the Gaffer can help with anything from the factory???

I rang TVR direct, just got the take it to your dealer line.

Whats the problem???

Well my central locking problems came back again (see Central Locking Problems on chimeara thread), very intermittent, would cost a fortune to diagnose at a dealer. Definately not the door pads, last item to check is the alarm to central locking interface, try to disconnect the unlock wire in case the relay in the alarm is triggering, can't find which wire it is and I can't remove a complete electric plug as the car needs to move to exhibit the problem.
Edited to add - or does anyone have a wiring diagram for a Foxguard F1-11 Alarm?

So the question that might be posed to TVR is: Does TVR offer refurbished '93-'95-ish central Locking Interface Boxes (16 pin Boxes)??? Or, can we early TVRs fit the later smaller CL unit ?? If so, how ??

Can anyone out there (Trade or otherwise) help ???

May be able to help a little with Foxguards. Basically, the alarm unit should have two large plugs and up to five small ones on one side. The smaller (10-way?) of the two large plugs controls the central locking and second cut. If the harness used is colour coded then the two white wires are the second immobiliser cut. If they are there at all the orange and black/red wires should not be used. The other six wires are central locking control. Hope this helps.

Unfortunately not for me, my central locking unit is a 6 pin, fairly standard easy to get, After all my investigation I think it's probably more likely a false trigger from the alarm, Ribol, thanks for your advice, sounds like you've been there before. Any chance you could mail me offline if you have more details of the connections on the alarm. You're right there are 2 main plugs 10 and 14 way, do you have any details on how the 6 wires control central locking?, thanks

Alarm circuits are virtually impossible to get because a) they either don't exist and b) it creates an ineteresting security issue.

If it is an alarm fault then I doubt you will be able to get any spares as Foxguard disappeared many years ago (I believe). The only alternative is to get a new alarm fitted.

I was told by my dealer that there is no such thing as a wiring diagram for a TVR, he said a lot of it was pot luck. He lifted the dash to be confronted by different coloured wires used in the same section with dodgy looking conections. It looked like a monkey had done it but it never went wrong and that was enough for me, infact the car was perfect with regards to electrical reliability.

SMB – It should be reasonably easy to work out which of the 6 wires does what. Briefly, alarm units interface with central locking in several ways. We can dismiss total closure and vacuum on a Chim as neither applies. That leaves you with positive pulse, negative pulse and changeover. As you have a 6 pin relay to operate the car’s central locking I cannot believe that even TVR would choose the changeover route so that is out. That means that there are two wires connected from the six I mentioned on the 10 way plug to the 6 pin central locking relay. All you have to do is establish if they are sending out a positive or negative pulse to operate the relay, one wire will lock, and the other will open. From memory the pulse wires are yellow and white (may have tracers) check them with a circuit tester whilst operating the alarm remote. If you have the black loom then you will have to work a little harder but you will still get there.

If I was going down Ladbrokes with this one I would have said it would be positive pulse because this would be the best way of doing it. But, it is a TVR................

Hope this helps, good luck and always keep a fire extinguiser handy

OK, the latest in this saga.

Thanks to T4TRV and ribol, I managed to bypass the alarm and take the car for a drive, and.......

the problem is still there, damn! Given I've either disconnected or replaced ( CDL- Central door locking relay) every part now including the door solenoids, I have top suspect either an intermittent earth fault or power fault. Earth would surprise me as everything else works fine, does anyone know which earth point the CDL connects to ?

Next step is direct connections to the battery, (probably worth adding these anyhow)?

thanks

Cannot remember how this little problem started but I seem to remember that the C/L pulsed as you drove along, is that right? I cannot remember from the original post whether it locked or unlocked the car when driving along, which is it?

If the car is locked or unlocked, I get the relays tripping and the solenoids chattering, just like the usual door switch problem ( except it isn't).

Sometimes when I come to park and lock the car it won't lock either, have to try 2-3 times before it will.

SMB – you need to cut down on some variables to help speed up your progress with this problem. Which of the following is what actually happens?

You get in car, lock doors from inside and drive off down the road until problem starts, when it happens it unlocks the doors and keeps trying to do so.

You get in car, don’t lock the doors from the inside, drive down the road, when problem starts, it locks the doors and keeps trying to do so.

You drive down the road, problem starts and does not either lock or unlock the doors.

Ok, here we go.

in all below cases assume we are in car.

1 - lock doors with central door knob, drive down road - after 5 mins relays starts chattering. Door unlock and remain unlocked, but chattering continues

2- don't lock doors, drive down road , chattering starts, remains unlocked, chattering continues

Additional info from today

OK Car now refuses to lock on alarm, it tries to lock then immediately unlocks - just like if you left a door open, and interior light( which I normally have in the off position, but for testing turned on today) tells be that the trigger circuit for unlock ( doors open) is on. Now I know it's not the door switches, I've had both removed. The only other unlock trigger I'm aware of is the alarm?, any other thoughts?

thanks

Then he's never seen the Bible has he? Plus, the chap who had my last Griff before me had some trouble with the headlamp wiring and managed to get a chunk of wiring diagram from the factory. I think your dealer is just taking the 'easy/let's charge for poking it about' route.
