Keep in mind that the art and science of battery maintaining goes to very long term storage of batteries where the goal is to supply an EXTERNAL source of energy that offsets internal leakage that will ultimately discharge the battery if left unattended. In the case of an SLVA battery, this self-discharge current is quite low. So the routine application of a maintainer between flights during the flying season is probably of no great benefit. Keep in mind too that the devices we're discussing are also capable of recharging a battery. While not robust, none of the charger maintainers would be hard pressed to get a 10% battery back to 100% in 24 to 36 hours. Any time a battery is recharged, terminal voltage of the battery right after removal of charge current will be much higher than the ULTIMATE OPEN CIRCUIT voltage of just under 13.0 volts at room temperature. In may take many hours for this so called "surface charge" to bleed off such that a maintainer can settle into the task of long term storage duties. I think the critical review of a charger/ maintainer is to see that it does conduct a reasonable charge-top off cycle that doesn't go much above 15 volts nor less than 14 volts. The TIME it spends in the top-off mode will be a function of how deeply discharged the battery was when the charger/maintainer was connected and exactly where in the 14-15 volt range it decides to operate. But at some time consistent with recharging duties, it does drop out of the charge/top-off mode. The system voltage may not drop to the ultimate maintenance level for many hours. So once your charger says "I'm done", come back a day later to see what the maintenance voltage is. It should be 13.0 to 13.5 volts.

It is a switchable 6/12 volt automatic charger / maintainer with 3 selectable charging rates of 2, 4, or 6 amp output, with a microprocessor control. They recommend using the 2 amp for trickle charge or charging small batteries such as lawn tractor or motorcycle. The 4 amp is for medium charge of automotive batteries, and the 6 amp for fast charge of automotive / light truck batteries. In your years of experience with charge rates of batteries, do you think the higher rate of 6 amps would even damage a small garden tractor battery? When I look at automotive alternators with 50 amp outputs I wonder what are the limits that will cause damage or shortening of useful life of a battery, provided you don't overcharge?

The internal switch is designed for lazy American convenience, not necessarily to be a failure. Personally they can remove the whole 6 volt thing for me. Last 6 volt anything I had was a 52' International truck. And positive ground at that.

From: Erich_Weaver@urscorp.com My landing lights no longer wig-wag and I would like to trouble shoot. My system is per one of the options described on the Aeroelectric Connecti on website (?), and uses a single three-position switch for the landing li ghts (off-wigwag-on), a bridge rectifier, and the flasher unit, all wired pe r instructions. Everything is fine for both the off and on positions, but nothing comes on or flashes at all in the wigwag position, and my ammet er indicates no current is flowing. I pulled the three-position switch and tested it with a multimeter - seems to function fine. That would seem to leave either the flasher or the bridge rectifier as potential culprits. Could just buy both and probably be done, but Im sure there must be a w ay to trouble shoot these to confirm which has the problem before I order them. Suggestions? thanks Erich ________________________________ Message 8 _____________________________________ Time: 06:33:51 PM PST US From: "Chris Hukill" Subject: AeroElectric-List: ANL current limiter mount Has anyone come up with a mount for ANL current limiters that don't look like they belong on a tractor? The standard ones in use are either bulky, ugly and unprotected or the ones the boom box crowd uses are made of plastic, and don't belong forward of an aircraft firewall, in my opinion. I have two alternators that I need to protect and could gang the ANLs together, or maybe it's best to use inline protection as close to alternator as possible. What has anyone come up with? Chris Hukill ________________________________ Message 9 _____________________________________ Time: 09:31:42 PM PST US From: "Chris Hand" Subject: Re: AeroElectric-List: testing for inoperative wig wag? Erich - I have the Aeroelectric type setup using B&C's SSF-1 flasher. When I was researching and planning my wiring and lighting setup I was told the flasher unit has a limited life and needs replaced periodically so installed mine to allow for quick, easy replacement when it eventually fails. If power is getting to the flasher and the wig-wag is not working, I'd replace that first. I believe the B&C SSF-1 unit can be found in local or on-line auto parts store as TRIDON EL13 A-2 flasher (ALT/FLASHER/150W/Ch +12V). Those are the part markings I put on my electrical system drawings and if I remember correctly, I got those off the flasher unit before I mounted it and confirmed via some on-line research at the time.
