Glad to hear you caught it.
Did you find out if the fuses were incorrectly rated or was it a PO "upgrade"? Do you have the fusible links still?
I have battery isolators on my Jeeps and the isolator key is on a cord from the ignition key. When I am not in the Jeep there is no chance of an electrical fire. Sounds smug but I leave my Jeeps for days sometimes and I just want them to start.
