Title: Battery or Alternator ???????
Post by: chrisgarrett on May 24 2011, 03:25:31 PM
My battery keeps losing it's charge.  I have to keep it on the trickle charger.  I'm assuming it's the battery and not the alternator.  The battery is about 6-7 years old and the car is only driven seasonally and occasionally.  I know there is a possiblity the problem could be the alternator and not the battery.  Is there a way to find out without removing the alternator?

The battery is beyond it's useful life. 3-4 years is a good rule. Even on a trickle charger and minimal use, I would replace it every 4 years. That being said - how long does it take to lose it's charge?

Not sure, but I'm thinking overnight, if it's not on the charger.

You need to order a gold plated 440 gigawatt alternator from "power sons of bitches" and put a 2 gauge wire between the alternator and something something :phpbbt;

Only if you install 4 red's volt boosters in tandem.


Steve's head is going to explode.

Jesus, dude- just take the fucking battery to Wally World or any auto parts store for a free test.

I would start by replacing the battery - but overnight is pretty drastic.

I see Kirban's is having an alternator sale.

7 years. How long did you expect it to last?
I'd assume for now the alt is good if you see over 13.2volts when running.
Who does it better than Steve and Ed:

I'd also say the battery is too old.

So how is it that all these die hard GNX owners that say they're cars are all 100% original still using the OEM battery that came with the car?

You think they have 24 year old batteries?

I wouldn't think they would, but if you look at some of the ads on ebay or tb.com for a GNX they'll usually make a comment about how the OEM tires are still on the car as well as the OEM battery (or that they have the OEM battery in some kind of sealed container).

Go spend some of your ice cream money on a new battery.

Yeah, I'm getting a new battery today and I'm having the alternator tested.  If the battery and/or alternator are compromised, can it effect the driveablility of the car?  Yesterday, I started the car and it ran up a very high idle (1800rpms) and faultered and finally died.  It showed a code 34, but I think that was just because of the high idle.  Any ideas?

If the battery was stone dead the ecm may have to re-learn. Put the new battery in and drive it. should be ok after a few miles.

Well that figures...I go out to the garage today to check on the GN after someone got into the daily driver and stole my Magellan.  Go to turn off the alarm and nothing.  The batteries in both remotes were dead and so was the car battery.  Hooked up the battery tender and BAM!  The Viper goes off along with the damn pain generators with the garage door closed.

Well, using that logic, they would have to have the factory oil fill, and air in the tires. I think allowances are given for certain items.

Alternator was bad.  Replaced it and the battery; all is good.  thanks

I am sure the battery is just old and tired.  When a battery is in doubt and discharging, you can disconnect one side and then see if it still discharges.

Your code 34 might have been from the chip losing its settings due to the bad battery...or it may not have been.  Fix the battery problem and then see what happens.  Electrical stuff gets strange sometimes

I had the alternator tested and they told me it was bad. Replaced both, took it for a spin and all is well.

Just stupid to steal, those things are worth so little new nowadays...


That's what the policeman said to when I filed my report.  He said none of the local pawn shops will take them anymore because they get so many.  

Odd thing was that they didn't touch anything else or toss the interior looking for valuables.  The kenwood deck was worth 5X the GPS, and my sunglasses are probably worth 2X the GPS.  What I did think was funny is that I use a Bracketron A/C vent mount kit and they must have broke it trying to get it out because bits and pieces of it were lying about in the car.  They went into the glove box and fold the W/S suction cup mount but left it on the seat.

I musta been thinking really slow before I replied.

Next time you replace an alternator, use the 94-96 Impala alternator which is the second generation of ours..puts out quite a bit more than ours. :)
