ok, had minor issues like a hurricane (Irma) basically hit me dead on with the eye where I live. I managed without power for 9 days and now have a battery to start diagnosing the Mariner.
I will post what happens when I turn the key, if it turns over at all - ill check for spark.
we can go from there. still doin some clean-up. I'll do the start test in the next few days.
