$%^$*^%#^*%$%^)&*(&%!!!!!!!! Alternator!
 
Puked on me this morning. Limped in to work on 9 volts. Trans wouldn't shift out of 3rd. This is a warranty replacement alternator that went in just before WCBF.

That's 3 in two years, all for different types of failures.

Kennginn 08-25-2004 10:03 AM

my brother had the same thing with my brothers jeep 2 days ago except his lights was off and i got him a brand new one from NAPA 8)

What alt you running? My DP 200 amp one has been flawless for me.

willwren 08-25-2004 12:19 PM

First DP 160 had a case seperation, causing a front bearing and shaft failure. Replacement was shipped with the wrong pulley, shredding 2 belts at WCBF/Woodburn Dragstrip. Swapped pulley from failed unit to warranty replacement, ran fine for a month until this morning. Total electrical failure.

PontiacDad 08-25-2004 12:51 PM

Sorry to hear, how is the belt tension? Too much will take out the bearings.

willwren 08-25-2004 02:55 PM

Bearings are fine and smooth. Mechanically perfect unit, total electrical failure only.

Merlin 91/97 08-25-2004 05:18 PM

Sorry to hear about your alternator Bill.
I went thru 3 or 5 w/ the 91 before I put a huge one in..... go with a big one like I did.... zero problems since.

willwren 08-25-2004 06:37 PM

Merlin, this is the cream of the crop. DP 160-amp, one month old warranty replacement unit.

DrJay 08-25-2004 07:31 PM

Well quit blasting Jay-Z through your 4 15's and you wouldn't have this problem! :lol:

Same here,200 amp DP so far so good .

willwren 08-25-2004 09:38 PM

As far as I know, I'm the only one with problems so far with these units. I've spoken directly with the manufacturer in the recent past, and will do so again tomorrow. It's encouraging to know that both of my failures were different. Totally different failures. No trend. Still a PITA.

My crappy 105 spare will be going back on in the morning when my boss brings it in to work. In the meantime, the battery is charging, and will be enough to get me to work and back tomorrow.

driverjohn2005 08-25-2004 10:39 PM

well, that sucks.....

coming from a guy who replaced 3 in 1 year!

Kennginn 08-25-2004 11:56 PM

man ur at 3 i am at 4 in under 6 months i think i might need more power

2000SilverBullet 08-26-2004 12:03 AM

Will - I am wondering if the 160 A and 200 A DP alternators are rated to the same standards as the OEM units.
My original 125 A alt has more than enough for me with absolutely no problems since new.
Maybe your new 160 A unit is really the equivalent of a less than the OEM 105 A unit and the 200 A unit may be a little better than 125. :?

Muslimsteel 08-26-2004 01:52 AM

That sucks mine has failed a few times too my dad can do a swap on those so easily now heh he bought the parts to change mine to a higher amp one but this one has been going on strong for probaby 2 years now very odd how things work out like that....

Damemorder 08-26-2004 02:11 AM

Haven't lost one yet ;)


(now mine are going to go like clockwork every week 'cause I said that....)

markwb 08-26-2004 06:08 AM

Sounds like voltage reg. failure on this one. Sorry to hear of your woes with these alternators. Just a suggestion, have some one else install the new alt in your car. Don't touch it. :lol:

Just don't ask Will how to remove the serpentine belt when it does happen!

BTW, what's that hissing sound I hear coming from your tires? :)

Paul, I have a good (new) 105 amp spare, and it can't keep up. It produces much lower voltages acroos the board. It's going back on this morning, and I'll confirm it. My stock 125 amp alternator never produced over 13.6-13.8, and my 105 spare only produced 13.6 MAX (my car has the heated ws, so it came with a 125 stock, where most 92-99's came with a 105).

1993 SLE 08-26-2004 10:58 AM

See that is funny my voltmeter in the car only shows 13.7 all the time and i have a 140 AMP AC delco

Will did u actually test the voltage coming off of the Alt and not trust the gague???

1993 SLE 08-26-2004 11:00 AM

See that is funny my voltmeter in the car only shows 13.7 all the time but at the Alt. it shows 14.4 and i have a 140 AMP AC delco

Will did u actually test the voltage coming off of the Alt and not trust the gague???

willwren 08-26-2004 11:17 AM

My gauge reads dead on. Reads the alt output when the car is running, but currently reading dead on what my voltmeter reads from the battery. (this is an aftermarket voltmeter obviously, as I have a boost gauge in place of the OEM voltmeter). My DP 160 alternators both read 14.2 during the day before their respective failures. Drops to 13.8 if I have lights, Climate Control, and stereo on.

willwren 08-27-2004 10:52 AM

100% warranty replacement being shipped as we speak. Good thing, too, as my NEW autozone 105amp spare charges 13v at idle during the day, and less than 12 with the headlights.

opensourceguy 08-27-2004 11:18 AM

now you know how I feel ;)

Nearly All reman units (this one is a reman) only fix what was wrong. 99% of the remanufactured alternators only fix the failed part, where it's bearings, brushes, regulator, etc. Only top level ones are done new thru and thru.

I'm in the same boat as damemorder, never had an issue with one yet, 120,000 miles will roll tonight, and my output is great for a stocker with the drain it sees. I only worry about it when the stereo is cranked, the HVAC is on full speed, lights are on (especially those Hella's). The High speed fan switch sucks a big amount at first too.

willwren 08-27-2004 02:36 PM

FYI, these alternators we get from DP are NEW AC Delco alts off the shelf, then modified for higher output and improved life.

Just curious
Im new to the bonneville game and i have a big
stereo thats only gonna get bigger and want to
know where all these 140 and 200amp alternators
are available from and if they made a differance for
all you guys out there with big stereos as well.
Mines an 88 SSE Series 1 engine.
Thanks
Nick ,V
(PS im in Canada if that makes a difference)

opensourceguy 09-06-2004 08:56 PM

What kind of power you pushing? Good rule of thumb 1,000 watts = 1 Farad of capacitance.
