I am at a total loss on where to hook this thing up. I want it to operate like the old style amp meters. Left discharge, right charge. I can not think of a place that would show both? If I hook it bat to voltage regulator that shows charging. If I hook it bat to 12v bus that shows discharge. The chip is bidirectional so it will read in both directions. Thanx for your help.

Therefore the only lead where you can measure this charge/discharge cycle is the main battery cable to/from the battery. (Or technically also the ground cable to the battery as an alternate) If you don't want to "see" starter currents, then you'd monitor the main cable feeding the rest of the system beyond the input to the starter contactor. You might want to research the usefulness of this information before going to this trouble however. The simple low voltage warning combined with over-voltage protection gives you much more valuable information, potentially much sooner, than any ammeter indication will. The low voltage light will grab your attention right away whereas it may take a while to discern a battery discharge on an ammeter especially if the discharge is small. A conventional ammeter measuring battery current will typically read zero most of the time. With light loads and only an ammeter you could potentially drain the battery to the point of being totally useless and never know until everything goes dark.

They don't give much information. Are there any 2 1/4" aircraft ammeters that use a hall effect sensor? I'm guessing they'd mention it if they did. -- Tom Sargent ________________________________ Message 4 _____________________________________ Time: 07:13:55 PM PST US Subject: AeroElectric-List: Battery Maintainer and Dual System From: "al38kit" I picked up the Schumacher 1562A Charger-Maintainer...It looks like a neat unit... Two questions...I would expect it should be a good choice for the odyssey batteries...right? When I get around to attempting to put a maintainer on a dual system with two batteries, any good ideas on hooking up a maintainer? Do you think a person should use two maintainers, or attempt to charge both batteries with one? I can see some potential for screw ups using one...

For my rolling fleet I use a separate 1562 for each one. Its hard to drive them all so the maintainer keeps them all topped up.
