I fount out my pretty alt was not working correctly. I ben reading on a 3G 130 amp swap. so off to the junk yard i went. (I should have read more and looked at what i got. This is a 3G alt, but it is out of a Ford Tempo. It would work as a second alt (On board welder) but the mounting ears are at 10-2 not the wanted 12-6)

This is the Tempo alt not what you want fof the swap. the plugs are the same as the correct one.

WRONG ALT THIS IS A TEMPO
see the mounts are in the wrong spot.

Here is the Back of the TEMPO alt. I decided i going to turn this into a welding alt. the mount will work great for that.

This is a TEMPO alt not a direct swap for a bronco or F150

Well another trip the the yard and i got this correct alt off a Taruas. At this time the pullies are wrong i need to swap them. i took them to AutoZone and benched tested them both were great alts and i had them swap the pullies. no issues.

here is another view before i swapped the pullies.

after i returned from the auto store here they are correct pullies on the correct alt.

Here is a front view. of both 3Gs

Here is the back. they are both the same connections minus the mounting ears.

This was taken from another web site, sorry not sure whom i stole this from but thank you. this is to show how the parts are wired

This is for the people swapping the later 2G in thier truck. this 2G has on the side. i was helping a friend do his and he needed this picture. again stolen from the web author unknown.

on my year i get to toss all this in the trash the regulator is now built in the alt and much cleaner install. The too was found on the web, author unknown.

Here is Jezebel wiring mess. you can see the regulator and all the wires that goto it.

I get to toss most of these into the trash it is a fire waiting to start....

Here is another view of the mess i going to remove.

there are a couple was to do the wiring. you can lookup Fireguy and his website and order everything you need or you can make your own.i could not wait i am a now person. here is his alt harness.

Here is the harness that was on the 3G. i just cut it longer at the junk Yard.

here is another view of stock harness.

Here is my home made harness. i tossed a couple of the wires in the stock harness. the new uses 3 wires i soldered and heat shrank all connections.

Here the harness is all connected and ready for install. the wire not connected it the IGN hot or on wire, when it senses 12V the alt turns on. the white went to the same location i did before and the yellow goes to the Bat+ post on the alt. easy install.

Ok-next issue when pulling a higher amp output you need to increase the charge cables. i wouls suggest to install a fuse and or circuit breaker. this will protect in case of alt failure. i went with the circuit breaker since i will not need to carry a spare fuse that would not be able to find when and if i needed it....lol

how this circuit breaker works when it gets tripped the lever pops out in the center. you just fix the issue and reset it and go.

Here are all the new wires. i planning on adding a second battery with the selector switc so i took the charge wire to the battery and a new wire from the battery to the starter relay. this is 2 Guage welding wire.

Here is the connection for the battery.

I wanted to have a power panel i could pull off fast if or when i need to replace the fender. I got the newer relay and mounted it the new power panel.

Here i have added the circuit breaker.

Now i am ready to start wiring this thing this is from the BAT+ alt post to the circuit breaker then to the battery..

on the 4.9 the bottom alt bracket was a adjustable bar i install the alt like the 2G was installed. the green and red is the 12V on wire. it connects to the green with red wire it was connected to before.

Here is a different view of the alt installed.

Here are all the wires connected. the plug on the bottom that is open right now is the power bypass for the fuse block and inside power needes. it get connected to the battery pos or the battery side of the relay. i was soldering new ends on the other pigtail so i can jut plug it in and go.

another view of the battery and panel connections.

i decided to chop out the connector and wire directly to a battery plus connection. you can see it on the top of the relay.

Last look at the battery connection. like the hold down?
