Great, just wondering if you would mind emailing me electrical diagrams to cover 1965 , 1966 perticulary for the charging system and all under the hood. I would be very grateful if you would. Thanks
By the way, looks like you have a 66 f-250? Question- do you know if there is an inline fuse involved with the charging system anywhere in the circuitry. I have new alternator, new voltage regulator, starter selonoid, grounding cable battery to block and have cleaned any contact points for grounding of charging system that I can find and still the alternator stays on all the time. I know that that can happen if there is a problem with the voltage regulator plug contact pins but the thing is that anytime I disconnect the neg. cable from battery, the engine dies. The alternator is new and putting out charging current to meet specs so shouldn't the truck engine continue running even with the battery disconnected??? This is why I am thinking that there is a inline fuse that has gone bad or there is still a grounding problem somewhere?? May with help of the elec. diagram I can find location of a inline fuse if there even is one at all. any help on this since you have f-250? my email address is : rayejohnson@q.com- and thanks a lot for help thus far.

An alternator need voltage to start charging, but once it is energized it should keep charging until you shut it off.
IF you unplug the voltage regulator and put a jumper between the (B+) wire and the(F) wire the alternator will go to full charge, see if it will stay running then, if it does then the regulator is bad or you have a wiring issue between the regulator and the alternator, and it could be one of those grounds.
PS; I lied, the hot lead is "A" not "B+" so jump the "A" to the "F"
PPS; had another brain fart, although there is no inline fuse, the large wire on the A terminal is a fusible link, it looks like a regular wire but it will burn up inside if shorted, check that between the alternator and the solinoid and between the regulator and the solinoid.

alternator 65 f250
I've been working on these trucks since they were new and have never run across an inline fuse. Are you sure it is charging? how did you determine this?

Thanks for the great info. soon as snow clear's will check it out. Alternator is a new rebuilt bought a week ago from napa auto parts. the fusible link is what I meant instead of saying inline fuse. I put on a new voltage regulator but the plug could be bad at the hot leat and between lead "F" will check it out. Thanks again

inline fuse
My truck is a '66 F100, but I would bet the electrical system is similar to yours. My factory shop manual is for a '66, so some of the numbers may not match yours exactly, but you should be able to find the same things. Group 13 - Charging System, page 13-2, Figure 1 shows the wiring diagram for the Autolite Alternator System - Indicator Light. Page 13-4 shows the trouble shooting logic tree for "Charge Indicator Light Stays On. Note 3 says check the operation of the voltage regulator. Even though you have a new one, it may be defective or there may be a wiring error. You're getting good output from the new alternator? Does it still measure good coming out of the regulator? Neither my '66 Wiring Diagram nor my '66 Owner's Manual electrical section say anything about there being an in-line fuse. Hope this is of some use to you.

charging light
My mistake, I was calling it an inline fuse and what I meant is "fusible link". That is what I am looking for. A fusible link in the wiring circuit in the charging system under the hood. I would say between the alternator and around the voltage regulator or back to the battery. I don't know what one looks like. any idea?? I know what they are for but they are built right into the wire I believe and do not know what would make them identifiable?? Any idea?? Thanks much for any help?

fusible link
with his testing equip. we will track it down hopefully. He has made his living as an aircraft mechanic for last 25 yrs. and lot of experience with auto mechanics. so if he can't figure it out, then I give up I guess. Ha! thanks again!

I do have the cats meow for 65 truck wiring diagrams...name your series...Ive got em all..from E series all the way to T series...email me with your needs...the book you always see everywhere I have and its sorta kinda close to the actual trucks wiring...but Ive got parts harnesses Ive compared the pamphlet to as well as my book...a FoMoCo published book btw...the Ford book its dead nuts on correct...

[QUOTE=EricJ;13636914]if anyone is interested I just went looking around and I have a selection of diagrams as well as component locations for at minimum 1965 and 66.
if someone has a place I can post them all, I will, if not give me your email address and i'll send them out, I have quite a few from different sourses, maybe 20 in jpg.
Im new to this sight just started rewiring the truck and desperately need the diagrams for a 65 pu. Previous owner messed it all up! And what wire colors go where on the ignition
