Re: Alternator Always Charging

OK, I get the picture now, thanks. Pretty elaborate, but apparently more reliable system. Hard to wrench it while standing on the side of the ocean.

Come to learn Model A, learn to be a sailor...

Re: Alternator Always Charging

The light dawns. That charge rate is appropriate to Li-ion batteries. Lead acids are not so finicky. I stand by what I said before.

What powers the alternator on a sailboat?

Re: Alternator Always Charging

Thanks for that. Looks similar to modern battery tenders. But I've never seen anything like that on a car. Maybe too modern for me. Learn something new every day.

Re: Alternator Always Charging

To MikeK's point - optimum battery charge voltage is 7.2 -7.9 volts for a 6V battery, twice that for 12V (14.4 - 15.8). Most regulators are set near the midpoint, 7.4 & 14.8, for fast charging with...

Re: Alternator Always Charging

You see the drain from the battery that the generator is not providing. I could have worded that better, I suppose.

Re: Alternator Always Charging

Ammeter is connected only between generator/alternator and battery. Horn and lights have no influence on it. Early models also had the coil connected on the battery side, but that adds only about 4...
