Hi Folks long time reader here in the forum but first time post as kind of become a bit stuck,

Have An 05 Vw Golf 1.4 Fsi BKG Engine code, fitted new battery but has a battery drain of 0.44 amps, now when i disconnect the exciter wiring plug from the alternator the drain goes away. I have replaced the alternator and is still the same!

I cannot locate a wiring diagram so am unsure where to look next? Is it a battery monitoring issue? Instrument cluster? Not sure where to go next?

ANy Help be great!

Are you locking the car and waiting for the all systems to shut down. Are there any other electrical faults on the car or aftermarket components fitted.

Open the drivers door, flick the lock to fool the conv the door is shut and watch the current drain. If it has not dropped after 5 mins pull fuses one by one. If the drain still disappears when you disconnect the alternator, the new alternator is US. I had FOUR genuine alternators from my TPS a few months back for a 1.6 Golf 4 before I got one that worked!

No other elec faults except windows aren't working?? Have pulled all fuses and drain still there hence why I went to the alternator to check, with exciter plug disconnected the drain drops down to 0.016 within 35 mins, but when plugged in is when I get the drain. Looks like could well be a faulty Alternator! I try another and let u know how I get on!

FiXED this one! Tried 2 more alternators and still the same, disconnected the ECM and instrument cluster and drain still coming and going when connecting and reconnecting the exciter wire plug! Found the main battery live feed from the alternator had melted into the exciter wire further back on the loom where it passes behind the exhaust manifold! Quick re wire and re route and all sorted!! Thanks for the help guys!

To be fair, I don't think you will get a more accurate description of the location of the ops fault.

If you can't see yours melted to the exhaust, you have a different problem.

It is usually in the bracket that holds the wring away from the front pipe.
