[quote:6763a8c142="Troy De Moss"]I recently bought a 1967 F-100. The person I bought the truck from had replaced the 240 six cylinder with a 302 v8 , no trouble there, but also replaced the alternator and voltage regulator with a GM alternator with a 2wire plug. The problem was it was not charging , and he had also cut all of the wires from the origional harness that went to the voltage regulator and alternator.I have installed the correct alternator , and voltage regulator , and replaced the wire harness to the alternator ands regulator. The battery is still only reading 12.4 volts with the engine running. I have good connections on all splices , and believe I have all wires correctly connected , but it is hard to find good schematics for 1967 . Please help .[/quote:6763a8c142]
Todays is your lucky day
Okay
Here's the color codes:
From Regulator connector IASF
I = Green w/red striped goes to the charge indicator light then to the ignition switch.
A =Yellow white dotted is tied in with the Black orange which is the alternator output wire going to the positive battery post.
S=White and black striped goes to the stator winding at the alternator
F=Orange and light blue is the field winding
Disconnect the regulator connector jump A to F what you're doing is full fielding meaning you are bypassing the regulator and making the alternator throw everything its got. If the voltage increases the regulator is Bad and if it doesn't increase the alty is the problem.
Hope this helps
