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

Re: Wiring issue
 

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.

Re: Wiring issue
 

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

Re: Wiring issue
 

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.

Re: Wiring issue
 

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

Re: Wiring issue
 

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

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

Re: Wiring issue
 

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]https://drive.google.com/file/d/0ByJ...it?usp=sharing[/IMG]

Re: Wiring issue
 

part between capacitor and fuse is nice and clean.

Re: Wiring issue
 

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.
