9N3 GTI Battery Drain


Recommended Posts

Wondering if anyone could help on this. I’ve recently bought a 9N3 GTI, it’s had a new battery fitted within the last month or so and it keeps going flat. 

 

I’ve taken the negative wire off and done a drain test, it’s draining at 4-4.5amp, so the battery goes flat in no time.

 

Haven’t had the time to start pulling out fuses, but wondered if anyone else has had any similar issues? Any help would be appreciated. 

 

All lights are off, boot light is disconnected etc.

First Welcome to the forum.

 

Try removing the main feed wire from the alternator, it could be the diode pack in the alternator has partially failed allowing the battery supply to go to earth through the diodes, there's a write up on it in this post https://www.clubpolo.co.uk/topic/335902-testing-your-alternator/

Thank you, I’ll give that a go.

If you haven't disconnected that alternator main lead yet, do realise that it is a direct feed to battery positive, so it is as well to disconnect the battery first, then  remove the alternator main lead and INSULATE the terminal before replacing the battery connection - otherwise sparks might fly!
