Exclamation OPEL ASTRA Alternator

Hi All,

Need all of your expert advice on a peculiar problem plaguing my ASTRA 1.6 1997 model. The symptoms are as under;

1. The hedlights and instrument lights are working like that of a scooter! Which means, when the RPM exceeds 3000 RPM, the lights brighten up and automatically start dimming after sometime!

2. The battery gets automatically discharged(Its a new Exide battery and there's no problem with the battery perse)

3. Roughly 8-9 electricians would have had a look at the alternator and allied systems and fiddled with the system including checking leakages etc which they never found or could rectify. This includes Metro Motors, a GM dealer where service is otherwise horrific.

4. Is it a problem with the alternator? If so, shall I get it changed? The alternator costs a bomb anyways!

There is (rather, ought to be) something called a "regulator" - an electronic circuit (usually in a sealed unit). Insufficient charging, random charging, overcharging, inadequate output, etc. are symptoms of regulator malfunction too. Ask the roadside auto-electrician to check the regulator.
