Re: charging system

Be careful about invoking Fleet Captain Husar's name when doing boat length and cost calculations. Keep in mind that he owns 115 feet of Cal. (And please don't ask him to calculate the costs!) Alfred Poor 1969 Cal 29 #132, "Pentaquod" How many Cal 20 sailors do we have on the list? I was reading Charlie's price quotes on the Cal 40 and 46 and I just smirked, thinking about my $900 Cal 20. Using his pricing method (boat plus necessary upgrades) mine is perhaps a $2,000 boat. Let's see...Cal 20 X 2 = Cal 40 (in feet). 2 X $2,000 = $4,000. Think I got a bargain. I know it when I go out sailing. Chris Campbell

So...what kind of ball-park numbers should I expect to see with our Balmar 100-amp alternator at low rpm, rather than the 6 amps I'm getting? I will check out the suggestions to trace losses on our next trip to PR! I'd just like a target to aim for... :-) Peter

Peter, it looks like the output does evaporate at low revs. http://www.balmar.net/PDF/Alternator%20Drawings/60-seriesdimensionaldraw ing.pdf Cheers Charlie From: Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com] On Behalf Of C.

On the Cal 40 we have the Zap stopped Balmar 100 amp alternator, ARS IV regulator, with Trojan L-16 house batteries, a link 2000 monitor, and a combiner. Freewind (Cal 9.2) is set up the same, but with Rolls 6V house batteries. We have the "non deep Vee" sheave on the alternator, so it doesn't eat belts as fast, and I believe it is the same diameter as the stock blue sheave that eats a belt every 100 hours or less. Belts used are Gates Green (xl). The most durable I've discovered. Using the link 2000 we monitor the batteries very closely. Our usage racing, with a laptop running in screen de-power mode after 30 seconds is @120 amp hours per day. With the lap top off we use @ 60 amp hours per day. Our regimen is to start charging daily @ 0600. We run the Vetus diesel @ 2,000 rpm, Usually for a two hour period. When possible, we top off the batteries once more at a 6 pm run, to around 1/2 the discharge. In the bulk stage @ the first hour the alternator maxes out @ 65-75 amps, until the amp hours needed in the batteries matches the output of the alternator. Then we see the alternator match the missing amp hours as the charge ramp progresses. So with a typical 125 am hour discharge we see @ 65-75 amp output until the discharge in the battery is equal to the alternator output.

Remember, that the alternator sheave typically doubles the rpms for the alternator. soooooo 2000 engine rpms is 4000 alternator rpms when reviewing the graph. dEmO From: Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com] On Behalf Of Husar, Charlie Sent: Wednesday, September 12, 2007 10:30 AM To: Ca… [at] yahoogroups.com Subject: RE: [Cal_Boats] Re: charging system (Peter) Peter, it looks like the output does evaporate at low revs. http://www.balmar.net/PDF/Alternator%20Drawings/60-seriesdimensionaldraw ing.pdf <http://www.balmar.net/PDF/Alternator%20Drawings/60-seriesdimensionaldra wing.pdf> Cheers Charlie From: Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com] On Behalf Of C.
