The 10 amp fuse for the right headlight on my 2001 Ford Escort keeps blowing so I presume I have a short to ground somewhere between the fuse block and headlight.
What I have tried
I purchased this cheap short finder off Amazon: SG Tool Aid 25100 Short Tester
I have followed the instructions that came with the device by:
- tearing apart a burned out fuse and putting the blades back where the fuse was in the fuse block
- connecting both leads of the short finding device to the ends of the fuse blades.
The instructions say that at this point the load in the circuit should be inoperative, but my headlight operates just fine using the short finding device in place of the fuse. I tried disconnecting the headlamp, but I could not follow the wire with the analog magnetic sensor. Maybe because of the metal it is under.
What steps should I take from here to fix the over-current problem I have that has burned out a few fuses already? I want to try replacing it with a cycling circuit breaker (one that would auto-reset after current spike). Good idea?
- 5 amps between fuse terminals
- 0.6 Ohms between either fuse terminal and ground
