10Amp ignition/meter fuse keeps blowing in my 96 Nissan Sentra, I think there is a short somewhere. What's the best way to start troubleshooting the short?

You will need a 12volt test lamp to trouble shoot the short and time. Make sure accessories are off for the test. First remove the fuse for the circuit in question. Next connected the lamp in place of the fuse. You are using the lamp as a fuse now to complete the circuit. Now turn the key to the ignition postion and begin testing. No light or dim light is normal, but a bright light indicates a short. Trace the circiut and disconnect wire connection when possible to narrow down where the short is. For example if you disconnect the circiuit at the half way point and the light remains on, this mean the short is located in the first half. If it goes out the short is in the second half. Remember to have the key in the ingnition postion in order for you to have power to conduct the test. Good luck
