Hi -  



I have pri and stby alternators & have 2 ammeter shunts feeding efis 

My ANL fuses located as close as practical to starter contractor.  Should the shunts be collocated with ANLs but closer to alts or as close as possible to alternators?



Other quick question is best source and type of welding cable suitable for RV8 in various locations fore and aft of firewall. 



Thanks in advance!



Warm regards,



Drum

Current is the same everywhere in the circuit, so mount them where it's convenient and secure.

I've bought welding cable through ebay, but if you have a welding supply house near you and want to 'buy local', they should have what you need. Amazon has it, as well. Any 'real' welding cable should have very tough and high temp insulation, and should have very fine strand, high strand-count wire.

Typically all those "hi-current" gizmos are co-located.  Don't worry about being close to the alternator(s).

I bought welding cable from zoro.com; you can search for "westward welding cable" there. Neoprene insulated, high strand count, meets SAE J1127 "Low Voltage Battery Cable" spec. In the world of welding cable, different insulation materials are available, I chose Neoprene because that's what bandc.com sells.
