60 Alt in a 55 - Alt not charging battery

[flaa1a]

My thread entitled "engine woes" is not getting any answers so maybe the thread is too long. I have installed a '87 60 alternator in my 72 55 with a 2F transplant. It has a 78 2F in it.

I unplugged the external voltage regulator. I jumped the W/G wire at the external regulator plug to a powered source in the plug. I jumped the W/B wire at the external regulator to power the "charge light"in the cab. I hooked the large charging wire (big W/B) that charges the battery from the alternator. I have checked the fuses in the cab and all are fine. I have had the alternator checked two different times at two differnt places and it checks out fine.

The alternator is not charging the battery. Can someone please help me? The Toyota shop manual says that some 2Fs have a fusable link from the alternator. I wonder if mine has one, but I cannot find it.

Thanks for your help in advance.

Randy

Can't help you unfortunately, but a bump to the top anyway! I'll be watching and learning from this one.

I have spent two weeks in my spare time trying to figure this out. Reading and re- reading posts from very smart cruiser dudes.....I am baffled. The things they have suggested that other people do, I have done, and still nothing. My fingers are crossed. I even paid homage to the cruiser Gods and bought a Silver Star! Hoping the karma kicks in soon!!

Is the IG wire at the back of the alt showing 12V w/ KOEO?

If yes,

Is IG still showing 12V w/ engine running & alt spinning?

If yes,

Is charge terminal showing 13.8V?

If yes, then alt is working. There is a fault that is preventing charge from reaching the batt.

I remember reading a thread in the 55 section last fall, someone was getting there 55 ready for a trip to the UP of MI. I think they were trying to use an alt from a 60 and having problems like you are. I can't remember who the original poster was, maybe someone else can remember.

I found the thread. You want to look at page 77, the rest of the thread is good too.https://forum.ih8mud.com/fj55-iron-pig-preservation-society/136996-resurection-beast-77.html

Thanks Sno! I will check it out. I read that earlier this week, but will go over it with a fine toothed comb. I appreciate you chiming in to help! I need it. This is odd.
