Hello everybody , Good Day For All ... I have This Problem and I think it from the (dynamo) how I can fix it without change ? Thank You .

@KhatabMKhatab - Well, when you're revving the engine, I'm seeing the charge light flicking on. This can indicate over-charge as well as low charge, so my advice would be to get confirmation of my suspicion that the alternator control box is failing, and don't drive the car meantime or at least keep the revs down under 2_000 because over-charge can fry the car's electronics!

@KhatabMKhatab

1. Diagnose
2. Gather evidence
3. Replace/repair defective part

In your case a simple diagnose means using a voltmeter to:

• measure battery voltage at idle then at 2000 rpm
• measure voltage drop between battery + and alternator D+
• measure voltage drop between battery - and chassis of the car

Tell us what you measured and we'll continue from there.
