#1: Electrical use affecting revs Author: Antknee, Location: ManchesterPosted: Fri Jun 20, 2014 2:03 pm ---- this might or might not be related to my other thread Injector open circuit
When the engine is running the revs change with the use of electrical features, ie windows, heated screen, lights, radio.
Thought it might have been the battery but tested and its holding its charge at 12.6, when runnig it goes up to 14.something but drops down to 12.something or 13.something with the use of the above
Not really sure where to look now, checked all the earth straps and everything seems to be earthed fine
Car is now a 1.4 petrol (TU3JP) if that helps, thanks!

It would be worth going to a garage and asking them to check the alternator with the correct equipment.
