That rather depends upon the nature of the "intermittent problem".
The easy (for us to say) answer to your question is "Yes ... and everywhere in-between".
(such as the inter-battery connections, and anything involving the frame if you're using that as a "conductor")
If it's an NCV3, there's always the infamous Y-cable (battery/starter/alternator .. with embedded fuse) willing to confuse things.
--dick (and that really is what i'd do if i were facing such an issue ... more than one connection can be at fault)
p.s. also pretend that i don't know what a "Great West" is mounted in/on ... T1N? NCV3? VS30? Model year?
