1987 crx hf alternator control module

[watson]

Can anyone tell me if there is such a thing as a alternator control module? My crx has a good alternator, a new battery, and good battery connections, but doesn't charge. I haven't been able to find the exact wiring diagram for the 1987 hf, but have found a reference in my chiltons.

If there is such a thing, where the heck is it?

Thanks,

Watson

I don't know where you would check for a control modual, other then the regulator that is built in to the alternator, I would recomend checking your cables for continuity as I've seen a few alternator cables go bad.
also, how did you go about checking the alternator?

Thanks for the response Ryland. When the car quit charging the first thing I did was check the cables and all related wiring. I cleaned things up quite a bit. When that didn't help, I swapped in a alternator from my parts car. The red light went out and I thought I had it whipped. My wife was not amused when she borrowed it and it went dead on her!

I bought a new battery ( it needed it) and drove it home. It was not charging, but at least the light was out. Then I took the original alternator to the parts house and had it checked, it checked out o.k.

I was puzzled. The chiltons had a " diagram" with reference to a alternator control unit. The local honda guy had told me that the hf had the ability to not charge when it was under load, in order to conserve gas.

In desperation I replaced the original alternator this evening and .....it put out 14.23 volts.

I think this car just likes to have me crawl underneath and scratch it's belly.

Thanks for the response,

Watson
