Am I worrying for nothing ?

Hi all,

After returnung from a run and letting my K1 idle on the drive for a minute or so, as usual and spot on time, the electric fan cut in - so far so good.
However, when I swithed off the lights off, I noticed the speed of the fan increased significantly.
Should this happen ? Apart from that everything is perfect - runs like a dream, starts 1st time every time and the battery is in A1 condition.
Any comments would be great
Cheers

Well I would guess that this is due to the decreased load on the alternator - at tickover the lights are a significant load, turn them off and the voltage will rise slightly and you will hear the fan increase in RPM.

Exactly!!

Less load on battery/charging system,so other components get more power to them.

No probs!

Thanks for that.
Yes I did consider your points and understand the logic.
I suppose I was comparing my electrics with those of my car. I mean, when I turn my lights off on my car, the wipers or heater fan dont speed up, so I couldn't fatham out why my cooling fan should speed up on my K1 - if you see what I mean ?
Anyway - I wont be losing any sleep over this one.
