Default Wierd thing happened 2 days ago

I had the Cobra in the neighbors garage for the last month. Before I took it there I returned it to stock so Dennis could get his X3 back.
So I programmed another device with the Dyno tune file and started programming it.....then the battery DIED halfway through... FUDGE!

I put a battery charger on it and went back yesterday.
Plugged the X2 in and it wouldnt power up...WTF, dead device? Nope, worked fine in the Marauder.

Funny thing was, when I turned the ignition on, the fan was running full speed (like it does when you are loading a tune)
Anyway, the fuse that powers the OBDII port had blown. As soon as I replaced it, the tune loaded fine and away I went.

I thought this was a little odd that the fuse blew, thoughts?

When battery's get low and you are trying to control certain items, it can cause an amperage spike due to the voltage fluctuation of a dying battery. We see alot of weird things happen to cars at the dealer with low battery voltage car's. I have had accesory's turn on randomly, light's start flashing, relay's start clicking crazily. It's caused by backfeed and almost a retarded command by the pcm due to low voltage.
