Alternator specs

Anyone know what amperage our alternators are running? I'm guessing at least 100. BTW, I have a 2005 LGT.

 

I went to start it this evening and the lights came on for a split second (needle bounce and HID warmup) then everything quit completely and it was as if the car had no juice whatsoever; no noise from the starter, no lights, no nothin. Still not ruling out the battery (though it was replaced about 18 mo ago), but I want to get specs on the alternator JIC

 

Thanks

So I just went out and jumped it to get it started and tried to get some voltage readings to compare but I think I fried my voltometer (a cheap one from harbor freight). Anywho, my car is starting fine now following the jump but I guess time will tell if the battery will drain. I'll probably run it (if it starts) to get a check on the alternator and battery to be sure. Any guidance would be appreciated.

Can't help diagnose.. But here's the alternator specs

Thanks for the details, it looks like I'll need one with at least 105 A output. That's what I needed to know. The more I think about it, it's like the car grounded out and drained everything. If it was the alternator, I would expect a slower death. I'm going to hold up for now and see what happens.

Sounds like you're having the same problem I was having. When I turned the key to the accessory position (first click), the radio and lights all came on fine. When I went to start the car, everything went black.

 

Turns out it was a bad connection on the negative battery terminal (could happen just as easy on the positive side). Cleaning the battery post and the clamp worked for a little while, but eventually I had to change the clamp.

 

Good luck!

I think that's exactly what it was. I figured it out when I jumped it and noticed that the battery wasn't charging. That was both a relief and an easy fix!
