Finally putting a 3g alternator in my 72 highboy

[akforceten]

The new radiator and T-Bird fan are doing great! There only is one downside that I have experienced. While driving at low speeds or around downtown my volt gauge only shows the alt only putting out 12-13 volts. Well today I fixed the problem by converting to a 3G alternator. Now the volts are 14.8-15 volts at low speeds or running down the freeway! Well here's some pic's( I love taking lot's of pictures of thing that I do to my truck) The only problem I have is sometimes I forget to take the pic's(I get to excited doing the upgrade)




This what I'm replacing a chevy 100 amp alternator . Couldn't keep up with the electrical demands



Here's the new / used alternator ! I'm taking the front case loose so I can clock it for the 390 .



Clocking all done . I had to replace the stator cause it tested bad .I took it back for another test this time it passed . As you can see I'm re-tapping the tension adjusting bolt hole to a 3/8 coarse thread bolt, also put the v pulley on had to use a washer for spacing.



I got it in now the fun begins ! It's time for wiring hooray!



I'm finally done wiring it in .It was really simple should have done this from the beginning ! It's time for a test drive and so far everything is working great!

Thanks for posting. That is an upgrade I should consider.

did you have to cut any wiring to do the install?

[akforceten]

Only one wire . Green/red wire spliced to the green/red of the Taurus wire harness . clocking the alternator didn't involve any wire cutting .

I put a 3g in my 68C/S and what a differance it made.The install is so easy everyone should switch.It cures a lot of electical problems.

Why yes it does . It has helped with new 2speed electric fan and all of the other electric draws The next electric mod I'm going to do is the headlight relays

I would like to report the 3g conversion is working just fine! now were doing the 3g conversion to my 78 bronco .It definitely puts out the power. Should have done this years ago!
