Re: 2000 GTP...and so it begins...(LOTS of PICS)
Little bit of a frustrating day. I went to start the car with the remote and it said out of range, maybe 15 feet from me. It's had a few spots like that before, so I called the vendor I bought it from, who offered to replace it, but the quickest way to do so was to buy another one and send back the bad stuff. Yay, great customer service.
On top of that, the Memphis amp I just bought off craigslist was bad. The rear channels sound like a helicopter (oscillating), and the fronts had bad alternator whine with other cool noises. The guy I bought it from didn't answer my call, so I get to fix it. My dad repairs amplifiers and such on the side, so we'll be able to fix it. These symptoms are of bad capacitors, so we're starting there. I tore it apart and was confused, to say the least, lol. Here's some pics.
Capacitors on the ground rail leaking a bit, they'll be replaced. This might be the source of the alternator whine, and possibly the oscillating, but more likely just the whine:

Main power supply circuit, pretty straight forward circuit, easy to work on. I like this amp:

Capacitors on the right in the above picture, you can see one was leaking. Not too bad though, so I was confused. I later found out what happened, see those 10 tiny holes\dimples in circuit board? I think they may have served as drains:

Nothing to out of the ordinary, not really that bad. Then I took out all the other screws to take the board out and found this underneath. DAMN:

Electrolyte city. Something blew it's load. The case was spotless. Only under the power supply section, this is another pic where I found something else wrong. I short between 2 pins. The screw driver is showing what 2 pins were shorted:

This was doing the shorting, it was stock, but came right off with a poke. BTW this is taken on the case with no cleaning, so nothing was spilled on the amp:
So the plan of attack is to pull all 8 caps, clean the board with vinegar really well to get all the electrolyte crap off, and replace those 8 caps. That SHOULD fix it because these caps being bad would cause these symptoms. Some of them are probably good, but my dad has 8 of them already for me so it's free for me, lol.
