What could be happening is the coolant level switch has dirty high resistance contacts. If you remove the flying lead and put a shorting link in and run with that for a few days to confirm that its the coolant level switch. If this proves to be the case you can clean up the contacts by passing a few hundred milliamps through them. You can do this by using a 21W indicator bulb. Wire the bulb in series with the coolant level switch and the other ends connected to 12vdc from the cars battery. Then poke something in the coolant expansion tank and make and break the switch several times. What this will do is the clean up the contacts as when in normal operation the SID circuit only draws a few milliamps.
