Hello All!

So I have a 2006 Audi A3 2.0T FSI. I recently replaced the Water Pump, Timing Belt, Thermostat and PCV Valve. After this, my battery light was on after doing so. I figured I had messed my alternator up somehow or hooked it back up incorrectly. So I took it off and turns out I had managed to break part of the mounting bracket on the alternator so I replaced that completely (came with a new pulley and voltage regulator). The alternator had the B+1 and B+2 posts on it, and I only hooked up the B+1 after doing some research saying the B+2 didn't need to be hooked up (please correct if wrong). Battery still wouldn't charge at all. So I put a new battery in just to test to see if it was it, and I'm still running into the same issue of the battery not being charged. I then replaced every fuse relating to the battery and then some just to be safe, still didn't fix it. And now when I start the car, it will not rev the engine when I press down onto the accelerator.

I'm at a complete loss here and I'm driving myself up a damn wall trying to figure out what the heck is wrong with it.

I appreciate any assistance that comes my way.

Thank you very much,

Oh, I ensured all the fuses were the correct Amperage as well.

If anyone happens to have a wiring diagram depicting the path from the alternator > Battery that has all components listed in between (if there are any) I might be able to solve the issue through that.

Update!
I used a multimeter to test continuity and I noticed that the 200AMP SA fuse (pictured on the left of the fusebox) had none. All the other fuses did, so I'm 99% certain I've isolated it to this one little fuse and I'm going to get a replacement as quickly as possible for it.

Solved! Yup took that fuse off, it was blown, went and got a replacement and everything works fine now!
