Turns out its the connector/wires comming from the themostat which was loose causing a short. SA said they were able to get this to happen in the shop and it did blow the fuse. So the said that they would replace it for us at a cost of $250 which is minus the $415 we spent the day before. They also said I need a radiator(which I already knew). They quoated $1150 to do the stat and radiator but I opted to do the radiator myself. I hope this is the end of this problem.
