I recently purchased a 97 felicia and I'm currently weaning out all the problems to get it back on road I've already cleaned up the throttle to sort out the stalling issue but now I've noticed the battery light is always on.. It only goes off when I'm hitting the high revs.

When its on its only dim though so I'm slightly unsure where to go with it.

Topic moved to felicia/favorit section.

It's probably a dodgy voltage regulator inside the alternator, or another related alternator fault, sometimes it's more cost effective to just replace it with a second hand unit from a breakers yard but you can buy the regulator seperately from the skoda dealer.

Hi TeflonTom, i have the same problem and already have changed the regulator. The light is now weaker, but with the revs going up became brighter. I'm becoming paranoid about this!

The battery is now charging, the alternator with 14,2v/14,4v, and the car starting normally.

there are 2 separate cases:

 

1. alternator warning lamp does not go out when engine speed rises

prerequisites:

- alternator belt tension OK

- battery OK

- good earth of alternator case and battery minus

 

disconnect D+ cable at alternator that goes to dashboard (green wire usually)

switch on ignition.

if warning lamp does not come on, the voltage regulator or alternator are faulty.

if warning lamp comes on, cable D+between alternator and dash panel insert has short to earth or dash panel insert are faulty.

 

2. alternator warning lamp does not come on when ignition is switched on

prerequisites:

- battery OK

- good earth of alternator case and battery minus

disconnect D+ cable at alternator that goes to dashboard (green wire usually) and connect it to earth.

if warning lamp does not come on, wiring to dashboard or warning lamp are faulty.

if warning lamp comes on, remove voltage regulator and inspect carbon brushes (minimum 5-6 mm)

if brushes OK, the alternator is faulty.

if brushes not OK, the voltage regulator is faulty.

I will try it, but yesterday, after removing the alternator i realize i have a 90A alternator and the regulator i bought is to a 70A alternator unit. First of all i will change the regulator to a right one and if the problem persist try the first option because the lamp do the ignition test and after ignition is still on, not so bright but on, and after i rev the motor it became brighter still. Thank you so much for your time, i'm not a expert auto electrician or even a mechanic but i'm really getting annoyed by this!! And having feed back from people who knows is making me fell not so alone with my Felicia!  :p

Hi all,

 

Tonight, after work, i will dismantle (again!) the alternator and send to a friend that will replace the diode plate with a new one i meanwhile had bought. I hope that with the new plate and a new regulator i will finally have the ******** battery light turn off!  

Again, thanks you all.
