" I have had an intermittent problem of the ignition switching wire not making a good connection with the starter solenoid a few years ago. I spent a few hours to conclude the following:
After testing and tracing the single solenoid wire (yellow) - I pulled in another similar wire from the back of the ignition switch to the black plastic junction box area (f/n/s engine bay area inder the two relays). Using a crimping clip at both ends. The extra wire put on the outside of the wiring harness thru' the bulkhead and under the bottom widowscreen cover.
The result, I now have two wires doing the same job - getting the 12volts to the starter solenoid yellow wire which goes from the junction box area to the solenoid terminal. Been starting OK for about 8 years until today.
I assume this is one of those common ZX wiring faults - or just a dry joint - never did locate exact open circuit location.
However, connecting touching a wire between the solenoid terminal and the battery positive always turns the starter motor.
Hope this helps someone not going round in circles thinking it is the ignition switch, or starter motor. I this case just the yellow wire open circuit - sometimes. Ref: Haynes Manual page 12-33 Citroen ZX Diesel 1991 to 1993. "
