Int we all mate?Good luck with it, your having bit of a rough ride.right so thats ohm lol sorry for not being good with this stuff i worked in building industry for last 18 years i know very little bout cars or electrics im trying my best to learn
so set it to ohm and what setting within this? then car running yes? then where do i put the testing terminals? obviously to the cables from rear of alternator but both on same bit or one etc?
It doesn't matter what colour cable goes where from your tester when measuring resistance of cables.right so trace the wires from alternator see where they go and then stick a test lead either side? in any order? red to alternator etc?
