Read the wiki but still confused
Fitted a new radio to replace the 1980s version in my van but the analogue clock hasn't worked since
I have a spare dead red wire next to the live radio wire but when I connect them together nothing happens but I think it does come from the clock. How is the clock earthed ? Any help appreciated
The radio and clock are both fed from fuse 3 counting from the left hand side; the interior courtesy lights and cigarette lighter are too. It's permanently energised (obviously otherwise the clock would stop and the 'modern' radios would lose their channel memory). I reckon it's been interupted somehow, the clock feed is No7 on the dash connector block, the earth is most likely fine as the rest of your dash would be playing up otherwise. Check voltage at pin 7.
Hope that helps
As 1664 said, the radio and clock are both supplied from the same fuse. When I first got my van, I found that a previous owner had replaced the radio and disconnected the power forwards to the clock! Have a look behind your radio and see how it's connected.

Be patient with me regarding the testing of pin 7. Is it a case of putting the meter across this and an earth?
Why would the glass be anything other than half full?
Was about to check my spare instrument panel as it is handy at the mo but forgot this one is the basic one missing the clock. Can still see the trails so on the early with vertical plug it is pin 7 for power and earths via pin 5. No idea whether Theclash's van is early or late. With your 1989 van what2d, I'd have thought you would have a horizontal connector on your dash and with this the manual shows clock gets power from pin 5. Put red probe of meter (set to DC volts) on pin 5 of connector and other probe on something metal like the dash. You should see 12V regardless of ignition on or off.
So to make things clear
If your connector to the instrument panel is vertical to the side of the clock it is an early one and gets clock power on pin 7
If connector is horizontal and under clock it is a late on and power is on pin 5.
One thing that does go wrong with these clocks after all these years is the electrolytic capacitors pack in. This should be in the wiki if not already as there is a writeup here http://www.brick-yard.co.uk/forum/fix-y ... 72774.html on how to fix. Symptoms are the clock will be intermittent and the second hand may just pulse one tick forward then one tick back. Unsoldering the capacitors and replacing is fairly easy and since I did mine the clock has never stopped and keeps very good time.

Yes, I've just looked at the Haynes and that says pin 5 so my dash pin picture is obviously for an early van. Best make a note of that

Try running a length of wire from the battery to the 12v connection to the clock (i.e. the little screwthread bolt that the pcb plastic thing connects to on the back of the clock);
And another piece of wire from the other clock connection to the battery ground.
(Be careful as all these connections will not be fused (maybe add a little fuse to the positive wire if you have one handy))
See if that 'hot wiring' of the clock gets it moving - that should at least prove if the clock works or not??
