Snopusher - I've inquired about this issue in a previous thread, and never really got an answer.
Look in your battery compartment. Are there two cables, black & red, that are labeled "inverter"? And are the cables hooked up to anything, or are they just tied out of the way?
Mine are tied up, out of the way, with the red cable going to a 100a breaker, just above the batteries.
I do have an inverter, and everything seems to be running fine. I've attached a few pics. Let me know what you find. Thanks.
