Whilst my car is not physically moving (see gearbox thread!), I'm turning it over for 5 minutes or so a couple of times a week.
When fully warmed up (choke right in) and idling, a significant drop in engine noise (revs) is noted when I turn on my headlights! Is this normal behaviour, or is the battery slightly too weak, wiring a bit iffy, or faulty components?
I'm just curious really.... it's not going to cause the car to stall or anything due to the idle speed.
