This is a perfect example of why pictures are so important In diagnosis! Simon, you have an older two wire solenoid. There aren’t two coils in your solenoid, sorry I assumed you had a three wire solenoid.
When power is applied to the white wire in your picture, the coil should pull in and stay in. If it doesn’t, clean the slug (as I call it) and use a dry lube. If that doesn’t work, call Martin Diesel parts with your engine model number and buy a new one.
You mention that it is intermittent. If testing doesn’t provide consistent results and cleaning doesn’t help either, try a pilot lamp temporarily tied to the white wire to verify you have consistent power being applied every time.
