Tommy,
ahhhhh....
I wish I knew whether the egg or the chicken...
Seriously, I don't know what went first. The fuse blew when I had a lesser cooler installed, but I failed to check the condition of the cooler fan. Wait a minute! I gave it to a guy with a Chevy! And he says it works fine.
Maybe you're onto something here. Maybe the fuse went first.
I'll do some detective work there - maybe I'll pull that wire and run a new one from the switch directly to the fan.
The cooler has a 160 degree thermostat built in. I'll try to make sure it doesn't have a short.
Thanks for the different perspective.
Tom
