I have a 1999 Ford Winstar LX with a 3.8 engine. The number 10 fuse keeps blowing. It calls for a 10A which seems to control the temp, the speedometer, and the odometer. A couple of months back I put a 20amp fues in the 10 position (calls for 10amps) and it didn't blow until recently, now even the 20amp blows in about 20 - 30 seconds. Gone though 3 20amp in 2 days. The only other thing I can think of, is that I replaced the original alternater around the same time, but I think it's the right Bosch part (I think ?). Any ideas what the problem maybe ??

Thanks,

Most often it is the pressure switch on the brake master cylinder ... usually knocks out the speed control also.

Just for a test, unplug the pigtail that connects to the brake master cylinder and see if a 10 amp fuse holds.

12Ounce,

Thanks for your reply. I was looking at other posts and noticed that this might be my problem. Is it hard to replace and what does it look like? Do you know where I could find the part number ... either Ford ot Motorcraft ?
