Weber 34 ihc iddle solenoid wiring.

[Mauritx]

Hello,
Ford transit 1989, with 2.0 petrol ohc motor.
Carb is a weber 34ihc
I have a connection wire from the old VV carb (I suppose it was for the auto choke?? ) to the iddle solenoid to the webber carb but it has stopped working, I don't know where the wiring goes to check fuses or perhaps a relay? Do anybody know where this wiring is connected I suppose it is connected to 12v so when you tur the ignition it gets current. I measure 12v but it seems the current is too low so it is not enough to feed the solenoid. I don't know what happened.. some help?
