Does anyone knows of an alternator off another make or model that has a higher output then my stock 88' Dakota's and will bolt right up? I will eventually get some sort of an aftermarket alternator but for the moment I figured some larger SUV or truck in the junkyard must use the same bolt pattern and have a higher output?

 

My best guess is Rams 91-down with the LA engines should be the same, possibly with the higher amp rating. I would say take some time looking up the parts for both trucks and see if the mounting and wiring is the same.

 

"you need those three other wires..thats a std 87+ connector. my truck has it, my ol 99 had it and my 96 ram had it.

reason u HAVE to keep it is the ECU is your voltage regulator. chevy and some fords are internally regulated. but chrysler regulates the voltgage from a ecu signal. the internal brush size and count is what makes up the amp output. u have to go off part numbers to find the one u need. cuz your 65 and my 120amp are the exact same housings, connector, fan, and so on."

"Look for the factory tow package..... 120a..... I have it...."

This is mine it might be a 65A I have a base model manual everything and no AC. It looks tiny/thin, there is the major 12V output on the bottom..but what are the remaining 3? Looks like 2 smaller poles right next to each other (green and blue wires?) then a chassis ground?



Because I want to replace my positive wire from the alternator to the battery as well, run 1/0 gauge cable from the 1/0-G opening on my positive battery terminal.



I'm going to get another 1/0-G terminal for the negative side and upgrade that red 4G fender ground to 1/0. Also replace that stock black ground wire you see with 1/0-G. This is where it leads to; the water pump mount!



^ You can see it here in focus, should I just ground it directly to the block instead?? Or the alternator chassis??

 

The number on the alternator says:
5227673 (673 in larger text)
121000-2660 12V
8 '0-2
Denso

Which translates to a 55A alternator lol for a Toyota Tercel (same year range) but I have seen it listed online as a 75A as well:


RockAuto lists a 75, 90 & 120 so I bet I have a 75A. 120A is pretty high for a stock alternator right?? I can get one made by Chrysler or Nippondenso for $125-$135 (120A)

 

120 amp is good.

 

I'm curious if something like an S10, Ranger, F350, Suburban has something larger than a 120A. I can't even find much higher in aftermarket besides 200-220A for $600 (not worth it to me at the moment) I do have an extensive aftermarket stereo but I am not drawing many watts so I figure a 120A would do just nicely (plus I have power/heated seats, HIDs, soon to be power windows and AC).

 

120 amp is still more then enough for that. 120a is still for that good for a winch and kc lights and more.

Like I said Rams with the LA engine most likely will use the same type of alternator. Check Rams around your year, I bet they will have higher amp options.

 

According to RockAuto the Ram 3500 even up to a 8.0L V10 only offers a 120A and nothing higher.

 

I need to deff get back on this my stereo is killing my battery, hard kicking mids (things like snares) can such more juice than a woofer "boom"

Does anyone know if Magnum engine alternators are the same as LA's? (bolting pattern, 2 field wires, a ground and the main +)

 

If helps some 94-up Ram's Dakotas and Durangos with 5.9 V8 (some not all that came with the 5.9) had the 136 amp alt. It is a simple swap, that is what I did, I got one from a Ram 2500 5.9, even got one for my friends 04 Jeep TJ to swap from the POS stock 90 amp to the 136.

Now there is even a 150/160 amp version. 01-03 Durango with the 5.9. Good luck finding that one in the junkyard, I sure couldn't. Napa has rebuilt units for a decent price. Again this is a simple swap.

Here is great link on the different alternators. http://members.shaw.ca/j_e_e_p/Altupgrades.htm
I got some more part numbers if needed than that link for the 160 amp if needed.


Edit: Sorry I forgot you don't have a Magnum. Well this info is good for other members with the Magnums. Napa's site list specs including all the cars the part cross-reference for.
