Hello,
I've had to replace my alternator due to failure of the original. Prior to putting in a 65 Amp alternator, I attempted to use an alternator and regulator I had sitting in a Ford Ranger. That didn't work because of either a bad wiring job, or a poor regulator. I'm betting I wired it incorrectly.
In any case, when looking for alternators, the OEM is often pointed out to be an IR type alternator, I don't believe that Ford fits the bill, perhaps why i had so much trouble.
All of the above is just background.
I've put in an alternator meant for a later-model 410B or 410C. The 410 originally came with a 37amp alternator which worked I suppose. The 410C had a 65 amp alternator with a different and somewhat more rugged regulator on it. The 410B (what I have) split the difference, some getting the 37 amp alt, others the 65.
So, I wanted more power to help charge my new high-current gelcell batteries.
I've got every thing working as expected, save for the tach and alternator lamp. What happens is this:
I have the engine turning at 1500 rpm. watching the tach and alternator lamp, I see tach hold steady for 6 out of 7 seconds, and that 7th second the tach drops to about 1000 rpm, and the alternator light turns on. This cycle repeats over and over. I've not tested different rpms.
Note the engine sound doesn't change. The voltage sense on the regulator shows 0.2vdc for those 6 seconds, then spans 5 volts for the 1 second.
Where is this duty cycle coming from?
not sure if I'm asking in the right place, but i've given as much information as I can.
thanks,
Jack
