Alternator issue or? My battery light has been on for the last month or so whilst driving without any obvious adverse effects, & I have been driving it in test mode to check the voltage. It tends to fluctuate between 13.6 - 14.1v or so whilst driving. (This same voltage was also recorded at idle with aircon on max./high beam).

So I removed my alternator today to have it tested because at idle my car would sit at 11.5 volts. So when I tested my alternator it tested good, I went to 3 different parts shops to make sure.
Slow engine crank The 12 volt battery is a vital component of the starting system in Ford Focus. It powers the starter motor that turns over the engine. If the alternator isn’t charging the battery properly, the engine may crank very slowly and may not start. Slow crank is usually the first symptom of a dying battery.

Common causes of a bad alternator are fluid leaking on the part, bad driving habits, and extended exposure to corrosive substances like salt and water. Symptoms of a failing alternator are dim or overly bright lights, a dead battery. strange noises, electrical problems, illuminated warning lights, and engine stalls.

At 2000 rpm, there should be hardly any drop in voltage.if the alternator is ok. Even at idle, it should hold at 13v or more. If the battery warning light is on, and it never gets to 14v, then it is either alternator, or the connections to it. Check the fat wire from the battery +ve to the alternator, and the fat wire from battery -ve to the
A simple test to check the working of the alternator is by running your car; and then unplugging the positive connection of the battery. If the car stops, then you most likely have a problem with the alternator. Another simple test is to check your interior lights. An alternator charges your battery when the car is running.
