Hi,
When I turn off the side lights the engine revs falter (reduce) for a couple of seconds. It does not happen if I turn off other appliances.

Hello,

It sounds like the throttle bore is dirty. Start by disconnecting the battery and then following this guide.

Here are the headlight wiring diagrams so you can see how the system works. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken
