Question about 1984 Ford F 250
New alternator is putting out 11.9 peak. I can feel the regulator and see on meter that it is kicking in and out. Is it possible that there is too much resistance through the regulator? Could something else be drawing a heavy load while running? Thanks for the help in advance.
What is the temperature gauge doing?
Does it get to about half way, or does it barely get off cold?
If it stays fairly cold, then it is probably the thermostat jammed open and needs replacing.
The glow rail controller senses engine temperature to turn off the glow rail (about 50C).
If the glow rail stays on + short trips + winter driving with lights, defrost, heater on, lower air temperature, then the alternator cannot keep up with the glow rail staying on.

Do you have a big amp for your music? These do draw a lot of amps. If you see your meter kicking in/out you may have a short. Try to disconect any other devices. Start by take the battery loose, ck the Alt. output with the battery out of the circuit. Then ck your hitch wiring if any. I would not suspect your reg. yet. If you have an after market radio disconect that and retry.

It absolutely can be something else and I'd start with checking the tension and condition of your belts and the electronic grounds to all components as my absolute first checks.
See 11.9 is a little low and to get amperage up could very well be belt tension or faulty ground or a little of both.
