welp... Yet again, another great 105 amp NEW alternator went on the rig this weekend...

I just put this one on from the hammerz trip and it lasted up until my run to buck on friday morning. watched my amps, slowly drop and drop.

So WTF is wrong with this thing. This is my probably 10th alternator. The last one lasted over a year, with probably 7-8 trips on it. worked great. got a new one. and lasted maybe 10 hours. Im pissed!

Do you people think im just running her at full speed ahead and it dies quick. Should i think about getting a 140-200 amp. If i do have some wireing screwed up how do i find which component it is? I need a good wiring guy to help me out.. I'll buy beer of your choice!!!

Is running a one wire alternator an option? Thats what I ended up doing on a few of my camaro's and I was happy with them. Kranker seems to be having an alternator issue as well.....

did you ever determine which way the fan was spinning on the alt?

You could do what I do.... I usually sell the rig before the alt goes bad

Im running a mean green 160 or 180 amp 6 year old alt. its doing just fine!!!!!!

Well thats because of the ratchet strap/ adjuster thingy

Is it internally or externally voltage regulated? Are you reuseing the same pulley each time? Whats the motor out of ? Back before I had the internet I used to have to go to the libary reference section all the time. In the automotive part they have schematics for every thing. So is it wired the same way the factory wired it?
At work when I have multiple failures of the same componet I start by looking at the last thing I or the guy who was there before me touched. Just a place to start troubleshooting from.

Its a 105 amp from a 95 camero. chevy 3 wire, power, excite and wire back to bat. I've tried the one wire ones before with no luck. Maybe i should throw an amp meter on her again and see how many amps i'm acually trying to pull.

internal reg.
same pully

taurus fan, 2 other fans, that are usually on
hella 500's, 2 tractor rock lights, msd, cd player, amp tower speakers,

I know lights arn't the issue because i never really even used them on this alt, and they were not on when i started seeing volts drop.
different smaller amp
and other than that just your random things that need to be turned on once in a while...

mean green = $369 :jerk you:

fans use up more amps than most people think. with everything that you have down i bet you are running real close to 100 amps and could be very close to if not over working your alt so i would through an meter on there and turn on everything that your usually running on a trail on and see how close to the 105 amps it is. If its around 90 or so ya might want to look into a larger alt. I would think that it could be a regulator problem but since they are internal reg alts that your running dont think that would be the case.

2 batteries? if i recall right your running right at the max amp draw for that alternator. they dont like being run like that non stop. ya either need a second battery to handle some of that load better or step up to a higher output unit. thats where your issue is. and move your tranny cooler if ya havent already.

If you dont have the fan controller to run them at slower speeds when it is not that hot, then those fans are drawing big amps.
Why were you having trouble running a one wire alt?

The only use this alternator has seen was this trip really. No lights. Tranny fan is from a street bike, taurus fan takes about 25 constant amps to run maybe 45 to turn on, little summit heater on low, and yes I had my perko on both batteries this time... amp meter today after i get another alt. i'll keep ya updated!

$20 in gasoline + 1 match + a good strike = no more altenator problems.

Thanks B-tilton... dropping off the alt tomarrow at boyle future tech in auburn for a rewind. they say it runs about $100 for better sh!t. we'll see what happens. and im rewiring the taurus fan to run on low when i need it, instead of turning it on and off all the time... you would think after 7 years of wheelin this thing, i would have it dialed by now!!! :jerk you:

who is going to respin that alt for you, i have one that needs to be done too

boyle future technology in auburn 530-888-6290
They say they can bump up the amps from 105 - 140+ replace the rectumfier.... and check things out as to why things keep dying. dropping it off tomarrow morning. about a day turn around.

sweet when i get paid i will look in to doing that as well. let me know how it works

im glad this is a new topic. im having a serious problem getting my toyota to even turn over on its own. i put a new starter, battery, and alternator in and it ran for a few weeks and then crapped out. i noticed on the back of my new alternator that it was recommended i change my voltage reg out. so went to pick n pull and grab two off old model yotas and plugged them in. now all my gauges dont work and it doesnt turn over even close. anyone shed some light on my problem?

your first problem is its a toyota :flipoff:

damnit you know you dont need to point out the obvious! by the way i think im gonna keep it for now.

exo cage soon?

sounds like some grounding problems on your yota. check them out and make sure there all still there and tight. the more grounds the better!

i had the same problem when i first tryed to start the buggy. more grounds more better :thumbsup:

hmm yeah ive check most of my grounds and they're all good. it might just be japanse wiring thats failing on me? hahaha

for starting issues in be mainly checking the block to body, body to frame, block to battery type grounds. if there not there put some in and odds are it will work great after that!

hmm ill check it out today. im getting a complete wiring harness from an 85 and doing it all myself the right way. ive noticed the guy that had it before me attemped to do some wiring and its pretty shity. hopefully i can get her going again riding my bicycle to work every day is a biatch

WAIT.... are you sure it has Japanese fuses in it? Cause if they're chinese fuses then the wires have to be backwards.

i think setting fire to it might work

keep fn with it you will get it. its probly something stupid that your just over looking :thumbsup:

i hope so. tonights the night to resurect the damn truck. it shall come alive once again :flipoff:

My Problems are solved!!!!

hopefully

got my alternator back today, rewired.

97 amps at idle
178 amps at 2000 rpm

$100

I guess in my alt. plug the excite wire i had hooked up was supposed to be the alt light so by me sending 12v to it it kept killing my regulator. switched 1 wire and....

on the road again... on the road again....!!! fuckyea!

sweet, no more going home early for you :flipoff:

glad to hear its running again :thumbsup:

just got the wiring harness last night.
and bought a new voltage reg. gonna re-do every wire i can find. hopefully she'll fire up this weekend

good luck :flipoff: :kranker:

me and the brother were talking last night. and would my problem possibly be water damage to some of the wires?

has it been sitting in water if so look for the wires that are caroaded as fuck if you have a hood fender and firewall there should not be that much water getn under the hood.

well. i pretty much got all the new wiring harness in. just a few more small tweaks here and there and its done. i did happen to find a few extremely corroaded wires

i got it all wired back up last night. the truck tried so hard to turn over but would not fire up. im gonna check the spark plugs today just to make sure they arent fried. other then that theres one wire im confused about and its right by my voltage regulator and it looks to be a ground. whee would it go?? :kranker: :kranker: :kranker: :kranker: :kranker: :kranker: :kranker: :kranker:

to the block i beleave. not 100% sure though i will look at mine tonight and let you know :thumbsup:

thanx man. yeah i think it does go to the block. its only long enough to make it that far

mkay. so im now getting great spark and plenty of air. but she still doesnt start. so now i gotta check out my fuel systems i think my carb is fucked up

so did you get this thing running

well heres the thing. it starts up just about perfect. but if you dont keep ur foot on the gas it dies on its own. so i noticed the wiring harness i got isnt the same as mine. its kinda hard to explain

check all of the vacum lines, because when i first started mine up it did the same shit. all it was, was a loose line check those it might help

your timing wa fucked too man. or did the shock of it working make ya forget.

yeeaaahh im gonna put the old wiring harness back in tonight. when this is all over im going to pay someoen to do any wiring i ever run into

well i ending up making my own wiring harness tonight. and she started right up!!!!!! she idles alittle rough but nothing crazy. now i can start working on something else for a damn change :kranker: :kranker: :kranker: :kranker:
