Please please help alternator

[Andy grim]

Can anyone help put a new battery on the golf but it keeps
Going flat also my interior lights are flickering but when I rev it it stops could the alternator be at  fault please help

Yeah, probably the voltage regulator is gone (or its counterpart, maybe diodes). My money would be on reg though.

Ok is it a easy job to replace the alternator it's a 1.8 se cheers

5 minute job

[Andy grim]

Really not for me lol

[itavaltalainen]

Loosen both bolts, push alternator down and keep down, slide belt off.... allow alternator to come back up. Take both bolts out, off it comes. Fitting new one is reversal of above. 5 minutes easy.

Ok will give it a go when the ignition is on the lights don't flickerer but the minute the car is running they flicker but when I rev it it stops thanks for your advice mate appreciate it

Oh btw... I only mentioned mechanical connection. There is a connector to regulator that needs to be pulled off and one cable to battery also needs undoing (very good idea to disconnect battery first!!).

[Andy grim]

Ok is the regulator and the alternator one unit

[itavaltalainen]

Yep, regulator is a part of alternator, it can be replaced rather than whole alternator but you need to have an eye to check alternator itself has not been damaged by worn carbon brushes.


I put a guide together on how to change them, it's in German but pictures should be enough.
