Wiring issue

Make a "resistance" measurement between 1&2, 2&3

[bulldogface]

is seems like there isn't any connection between, reading is zero, and connection test between red pin and either of fuse pins is negative.

[bulldogface]

just ran test of suggested points with two meters. between 1 and two, zero. between two and three, 6.6 ohms..

[Richard L]

with the circuit board off the car, we can examine the copper tract easier. Do make the above measurements and I will make another picture meanwhile.

[Richard L]

It is strange to see 6.6ohm between 2&3. Follow the copper track run, it should be continuous. Examine it closely.

[Richard L]

It appears the red track is broken. (2&3)

Blue track ...... circuit board bottom
Red track ........ circuit board top.

seems like there is tiniest of circuit bubles, plus some black residue around the first solder point of capacitor, going thru hole. tried to make a pics of it, but i am not sure they're going to help...[IMG][/IMG]

[bulldogface]

part between capacitor and fuse is nice and clean.

Can't see the image. Post it to richard AT aquamist.co.uk

It looks like there was a spark created some time ago where the black is. Hence burn out the track.

If you can solder a bridging wire between 2&3, it should work normally after the repair.
