I have a problem with my auxiliary battery not charging.
My old battery fell below 11v and died, so I put a new AGM battery in and it fell to 11v too.
I'm now suspecting the isolator is not allowing charge to the aux battery.
Any ideas how I check it.
It seems to kick in after 10 mins but not for long. I drove for 3 hours and the battery didn't charge.
