When my solar panels are charging (~14V) and I try to start the
engine, it basically acts like the batteries are dead. No turnover,
just hear the click of the solenoid. I unplug the solar panels and
it starts right up? Any ideas what could be causing this? Wierd.

Is shore power (or another source) plugged in? Sometime solar's high
Voltage with low current confuses other sources.
