Just had them load tested yesterday and the three year old 6 volt trojan arms are OK.

Yes, I read that, and you said one was slow to recover. One battery can drag down the bunch. Were I you I'd hook up to just 2 good batteries and see what happens.

However, since your Mag is making funny noises, I'd say that's just as likely the problem.

It could very well be this too.
