Balmar XT170 case ground alternator - grounding

[UK Ade]

Thanks for the advice. I’ll do some testing of direct amps flow out of alternator. Following advice from Balmar changed pos to ARS-5 from Alt B+ post to direct from House Batt. Also started from 80% discharge. Massive difference - Amps on monitor showing 90/100 Ah. However temp got to 88c (will have to fit fan) and noted sig volt difference across House/Engine/Aux. May be due to the Cristec Batt Isolator. The Balmar Duo Charge looks like a good replacement (for the Cristec) but not sure how to configure a third output (Aux Bow Thruster Batts).
