Electric fans burning out the fuses

Heck, we even ran new temporary wiring to the fans on his car to make sure there was no intermittant short. But I hope this takes care of your problem as things like this can really be annoying.

Good morning Ron:
Tks for your quick reply, well I have checked all connections, changed the mini fuses and use mini circuit breakers instead, isolated the fans and checked the amperage with amp meter, the kick on as expected 205o the initial draw was approximately 50 amps and then goes down to 40-45 while running, turn off at 195o all this is normal. the fans are freewheeling do not show binding or hangups. Changed the radiator cap for a new one 13lbs vented, I was unsure of the venting of the previous cap. I did this because i noticed the puke tank side hose collapsing after cooling off but if it was vented this should not happen. So I changed the cap. I added water wetter to the coolant mixture. Check the online fuse of the hose temp sensor for the fans, that is fine. Test run the car (ambient temp 80o) open road remained at 190o, at a light stop went up to 200o all is fine so far. I will stay away from slow city cruising that is murder for these cars. So far this is all I have done.
tks
Lou
PS
Yes it could be very annoying
