Found on the annual as well the nicked field wire which in one flight probably caused an elevated voltage and hunted down a crimp on a fast-on which, after 18 years, was degraded to become a high resistance point (heating element). All fine now and plane back in the air with a good feeling for finding these points. Cheers Werner On 04.07.2021 16:57, Robert L. Nuckolls, III wrote: > > -- Good detective work!

I'm deep in the process of wiring my RV7 (most of the wiring completed), using a legacy schematic with EBUS architecture. Wiring to the battery contractor is standard--wire from contactor to switch (2-10) with ground to field of tabs at firewall. I have used a lawn tractor battery numerous times to energize the system when testing components as they're installed. All has worked well until this AM. I'd appreciate input to help me resolve what the issue might be. Thanks much in advance. -------- Frank McDonald Kitfox S7 912S, Sensenich Composite 3 Blade Acworth, GA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=502714#502714 ________________________________ Message 3 _____________________________________ Time: 02:41:35 PM PST US Subject: AeroElectric-List: Re: Melted battery contractor ground wire From: "frank3" It might be pertinent to mention I did not hear the typical "clank" from the battery contractor when I flipped the switch. -------- Frank McDonald Kitfox S7 - sold RV7 in progress Acworth, GA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=502715#502715 ________________________________ Message 4 _____________________________________ Time: 04:26:10 PM PST US Subject: AeroElectric-List: Re: Melted battery contractor ground wire From: "user9253" Have you made any wiring changes to the battery contactor recently? It seems that the melted wire is connected to positive someplace. One possibility is a shorted contactor coil, but unlikely. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=502716#502716 ________________________________ Message 5 _____________________________________ Time: 07:00:34 PM PST US Subject: AeroElectric-List: Buy New Apple iPhone 12 5G 64GB Original Unlocked $679 From: "jeiaery" The Price is Canadian dollar.
