    Subject: Broken Battery
    I have an Odyssey PC680. Its 18 months old and has been in the A/C as power whilst fitting wiring and instruments. Now after a full charge all I see is about 12 Volts and placing a load of 2 or 3 amps on it sees the Voltage drop to about 9.5 V in about 10 mins after which the EFIS and radio start to fall over. It has been run completely flat on at least on occasion, maybe twice. I am using a quality charger designed for AGM batteries. The local battery supply shop has tested it and gets the same result. I now have a new one. Did running it flat stuff it? Can it be bought back to life? By the way I paid $240.00 US for the new one, what are you guys in the States paying. I think the importer is ripping us off over here. Chris Byrne SYDNEY

    Subject: E-Bus Source Switching
    From: "dfmoeller" <dfmoeller@austin.rr.com>
    I am in the midst of some fairly major work on my zodiac and thought this would be a good opportunity to split the power distribution into a main and an e-bus. Rather than an e-bus SOURCE switch and a large diode as shown in the aero-electric connection, I was thinking about incorporating an AVIONICS-MASTER switch between the main and e-bus, and had the idea that a 2 pole, 3 position switch would allow e-bus OFF, e-bus ON, and e-bus ALT SOURCE positions, while ensuring no back-flow into the main bus from the alt source, thus eliminating that honkin' diode and its voltage drop. All from just one switch! Any reason anyone can see not to do this? Doug Read this topic online here: http://forums.matronics.com/viewtopic.php?p=110964#110964

    Subject: Re: E-Bus Source Switching
    Hi Dough, on the fast run 1 major :o) -single point of failure The difference between an E-bus and an avionics master is that on the e-bus you have all essential parts for a save ending of your flight in case your alternator fails, on an avionics bus you have all avionics equipment (if needed or not for essential requirements). I have the diode in place and the voltage drop is not a real problem, it's so minor and only there when anyway your alternator is sourcing the bus so I see no issue (if you want you can go to more expenses and get a part which has only 0.1V drop. The good thing about the diode (or if you have bad avionics (brownout) the bad thing) you have only one switch to get the cockpit live, so the KISS principle. br Werner (full electric, no steam gauges and happy living 288hrs with it) dfmoeller wrote: > > I am in the midst of some fairly major work on my zodiac and thought this would be a good opportunity to split the power distribution into a main and an e-bus. > > Rather than an e-bus SOURCE switch and a large diode as shown in the aero-electric connection, I was thinking about incorporating an AVIONICS-MASTER switch between the main and e-bus, and had the idea that a 2 pole, 3 position switch would allow e-bus OFF, e-bus ON, and e-bus ALT SOURCE positions, while ensuring no back-flow into the main bus from the alt source, thus eliminating that honkin' diode and its voltage drop.

    Generally on MIL spec terminals there is a metal band that crimps the insulation, this band is covered by the insulator. On cheaper hardware store/automotive copies the metal band is missing and all that grips the wire insulator is the plastic of the terminal.

    Perhaps even more important is the quality of the crimper. The typical hardware crimper isn't likely to give that 'gas tight' joint to prevent corrosion within the joint.

    I have seen spade connectors at autozone that had the metal that crimps the insulators. There were some other ones that only crimped the wire only but these looked like they could me of the same type.

    Subject: ring terminals
    What you are looking for is AMP PIDG (or equivalent). On the MIL spec (AMP PIDG), the metal part of the crimp sleeve is longer (deeper). They can look similar to the cheep HW/auto style from the outside. You have to look =93into=94 the sleeve and assess the length (depth) of the metal part of the crimp area. Ideally, the metal part is long (deep) enough to crimp onto both the bare wire and the insulation (if done correctly). This is rarely the case with the cheep HW/auto versions. On those, only the plastic part of the crimp sleeve crimps onto the insulation (which is insufficient to properly secure the wire). Unfortunately I=92ve found, most ads/catalogs usually don=92t clearly specific whether they are the cheep HW/auto type or the better Aero (PIDG) type. See here for AMP PIDG data sheet: http://ecommas.tycoelectronics.com/commerce/DocumentDelivery/DDEControlle r?A ction=showdoc <http://ecommas.tycoelectronics.com/commerce/DocumentDelivery/DDEControll er? Action=showdoc&DocId=Customer+Drawing%7F36161%7FZ%7Fpdf%7FEnglish%7FE NG_CD_3 6161_Z.pdf> &DocId=Customer+Drawing%7F36161%7FZ%7Fpdf%7FEnglish%7FENG_CD_36161_Z.pd f You can get the correct ones from here: http://www.bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?12X358218#s814r8- 10 at reasonably competitive prices (20 - 30 cents each). I=92d be interested if you find them much cheaper somewhere else. These also appear correct: http://www.aircraftspruce.com/catalog/elpages/insulterms.php Note in the photo, the metal part of the crimp barrel is nearly as long as the plastic insulation (versus only =BD as long as on typical HW/auto style.

    Subject: Re: ring terminals
    There are three differences between the hardware store variety of terminals and Mil Spec terminals. As others here have said, there is a sleeve that grips the insulation to spread the mechanical loads to minimize flexing where the wire exits the crimp. This is where the wire will work harden, become brittle and break. Secondly, the seam on the barrel is brazed closed on the Mil Spec terminals. Many of the hardware store variety are just formed into a barrel that will open when crimped unless the crimp is done correctly. The third difference is that hardware store terminals usually have vinyl insulation. The Mil Spec demands nylon insulation which will outlast vinyl many times over. In addition, Mil Spec products are produced under exacting quality standards. Go here to find a good variety of Mil Spec terminals and tools that properly crimp them. http://www.terminaltown.com/ Regards, Gaylen Lerohl Terminaltown.com ----- Original Message ----- From: Gerald Jantzi To: Aero Electric Sent: Saturday, May 05, 2007 10:52 AM Subject: AeroElectric-List: ring terminals I am told that there is A difference between aircraft terminals and hardware store terminals. are the ring terminals sold at aircraft spruce aircraft terminals or are they the same as hardware store termonals? looking for some feed back thanks Gerry ------------------------------------------------------------------------- ----- Don't pick lemons.
