There are two crimps and the mating pins, a total of 3 failure points for each circuit. And since there are 13 connections, luck in not on your side. :-) Straight wires with no splices would be much more reliable. How often will it be necessary to unplug that connector? Compare the convenience of unplugging that connector to the inconvenience of troubleshooting and fixing a bad connection. - Consider eliminating the 35 amp ANL fuse. There is a reason the main power bus feeder is not fused in Bob's drawings. If it fails, all electrical power is lost. Compare that danger to the chances of the feeder shorting out. If you practice good workmanship, support the feeder well, and double insulate it where it passes through the firewall, then it is not going to short out. - The shunt location is a matter of personal preference. I prefer to measure alternator output rather than battery current. Or eliminate the shunt altogether, one less thing to fail. The voltmeter will tell if the alternator is working or not. Nice schematic. Keep up the good work. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=490807#490807 ________________________________ Message 2 _____________________________________ Time: 08:55:56 AM PST US From: Bill Steer Subject: AeroElectric-List: Plug/connector question The battery on my Excalibur is difficult to access. As a result, I want to bring a wire from the positive side of the battery to a more accessible location so I can hook a battery maintainer to it easily.?? That wire will have an in-line fuse, but I need to terminate it with a plug/connector that will not expose the hot connection to any sort of ground.?? Does anybody have a suggestion about what sort of connector would be appropriate? Thanks for any suggestions.

Unless you're planning on start-cart level current, I'd use something like this, which is mfgr'd into many charger wiring harnesses: https://www.amazon.com/Sea-Dog-Polarized-Connector-2-Wire/dp/B000Y89TDM/ref=asc_df_B000Y89TDM/?tag=hyprod-20&linkCode=df0&hvadid=312430092407&hvpos=1o3&hvnetw=g&hvrand=4395166586976378804&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9013892&hvtargid=pla-569344392136&psc=1 The exposed black pin would be the ground for the a/c electrical system, and the connector can just be tucked out of the way when not in use. The exposed red pin on its mate would be fed by the charger, and shouldn't get powered until the connectors are mated. The q&a for that particular product indicates that the wire size is anything from 14 to 18 gauge (depending on who answers), but even 18 gauge should handle plenty of current from a slow charger. There are better, and much more expensive options; what are your goals?

That means that the exposed aircraft pin would be positive. One could reverse this but that's asking for trouble down the road when a different charger is available away from home etc. I use a cigarette lighter receptacle that happens to be on a manually switched hot buss. Not ideal but it works and for other reasons I wanted one hot lighter receptacle available even if the battery contactor was open. Ken L.
