Hi, noticed this morning that the caravan wasn't as hot inside as it normally is. Tested the current draw on the Ultraheat and found-

500w setting 2.5A stable

1000W setting 5A stable

2000w setting 9.5A but approx every minute the 9.5 A drops to nothing then approx after a minute it goes back to 9.5 A again. 

Thought it might be the stat cutting in/out but their isn't any clicking from the relays ???

Is this correctly working or is their a fault on the 2Kw setting. I cant understand why the current keeps dropping but no relay clicking when it drops.

Im Using a clamp meter on the mains cable coming into the van clamped around just the live core.
