time for new alternator but! i have a question!

[F 150Cobra]

the old alt is dead.. getting really hot and draining the batt in like 1 hour.. soo time for a new one but!! i found this one ( i dunno wich car its from )


here you can see it next to the stock one we use its the same bracket everything but uses 1 style wire setup is it worth the change? upgrade? orr??

That looks like a 3G alternator. Much better unit but it requires a bit of rewiring to make it work on an older truck. I think rjm injection might sell a kit for it.

its a 95 amp unit

It can be done the some of thr latter 300-6 trucks had them. To get wiring. SKan did a good write up awhile back about them . Basically heavier wire and a mega fuse will work .

As well as others.

I got mine off a conversion van high amp . I get mine rebuilt . For 1/4 the price of over the counter one.

 

[F 150Cobra]

oh how about a good wire with a 100 amp fuse??

 

[Skandocious]

Yeah you have to upgrade the wiring but I believe you also have to change the configuration if it's an older truck like yours. Something about how the new ones are one wire and the old ones are two wires. Like I said, I think you can buy conversion kits.

Here's a good walkthrough for upgrading, along with links to the needed parts:

From the looks of it, you might not need a conversion cable. I've not had to install one on an older truck so I'm not entirely sure.

http://www.allfordmustangs.com/Detailed/72.shtml. Can someone help me ? Install this? I'm not home and I wish I can see skans thread but I'm on mu phone thanks too what I understand the white wire from the small 3 wire plug goes on the + of the alt???

Jurgen like I said I think you have to do some modifications on your wiring. The 3G uses a separate stator wire whereas the older ones didn't.

The 3G model alternator feeds power through a high-power electrical terminal instead of the problematic spade connectors in the 75A model. The stator signal wire is located on a separate connector on the 3G model. Because of these differences, the stock wiring harness will need modification before the 3G alternator can be put to use.

All I need now is to buy that harnass I'm using a 8 guage wire and its getting warm its not enoug

 

[Skandocious]

Yeah I would upgrade to a thicker wire. 8 gauge is not big enough.

Glad you got it going. Sorry I was grumpy when you called-- you did wake me up

haha ok no prob! thanks for the help tough

 

[F 150Cobra]

what guage would you recommend?

 

[Skandocious]

The kit on RJM uses 2 gauge wire-- I would try to copy it if you can:
