It is not enough to fully energise the solenoid to pull the contacts together, but just sufficient to hold them together once closed.
If it goes when you turn the ignition off, the only place such a small current could come from is via the ignition warning lamp. This would suggest a short between the current coil and the voltage coil in the cutout. That is where I would look anyway.
Hope this helps.
Thanks for your thoughts David. The two coils both occupy the one bobbin which makes such a short difficult to isolate. I have my suspicion that the correct polymer (formerly Shellac) insulation may not have been used when the cut out was restored as what may only be paint has rubbed off in one or two places. I will get the auto sparks chap to take a look tomorrow.
