A couple of questionsÂ on this connection. Z101 calls for a 12-gauge FLW butt spliced onto the 10-gauge main alt B-lead wire.Â 



I didn't see any this large at Spruce, but it appears that both Amazon & AutoZone have the Dorman splices in 8 gauge. Is this a satsifactoryÂ product for our needs?Â 

https://www.autozone.com/miscellaneous-non-automotive/electrical-wire-connector/dorman-conduct-tite-8-gauge-butt-connectors/422502_0_0

Also, are there any special techniques required to ensure that the smaller wire is propertlyÂ gripped in the slice when crimped? Do I need to put some extra wire strands in there to fill the connector & snip off any excess?Â 

Thanks!

David

David,

I classify those kind of connectors as "cheap automotive" wire terminals and would not recommend them for use is aircraft.

Do a search for AMP (is Manufacturer) PIDG (Pre Insulated Diamond Grip) butt splice for something that looks like this:

   There should be a 4AWG spread between the protected feeder

   and the fusible link stock. So the 10AWG feeder from the aux

   alternator gets a 14AWG FLW. That's the case in the

   last iteration of Z101 (rev B).

I made a mistake in my question.Â  The main alt Â  lead is 8 gauge & joins to a 12 gauge fusible link.Â  That's the size butt connector I'm not seeing at Spruce.Â  The yellow amp goes up to 10. Â

You would need crimping equipment of       the right size in order to use a crimp type splice.Â  Even assuming       a quality connector is available, doing it once or twice may not       justify getting the crimping equipment required or gaining the       practice needed to do it 100% effectively.

     

     

     I'd suggest a solder type butt       connector sized for 10guage and then stuffing the 12 guage side       with extra strands as required.Â  All you need is solder and a       torch to get it done.Â  Big item like that is easier technique-wise       than smaller solder work.

Yes, I was leaning toward the soldered lap joint approach. I considered crimping ring terminals on each wire end & joining them with a 1/4" bolt/nut assembly, but the 8-gauge crimper again becomes a problem.Â 



Thanks to all for the advice & ideas.Â

Don’t know if these butt connectors would be of use here, but I am curious what Bob thinks.  This URL goes to a Summit Racing site and shows that application.  Looks pretty slick to me.
