Why does the fuse keep blowing on my ignition switch?

If this power fuse blows only when you turn the key to the START position, remove the 3/8″ terminal wires from the solenoid, then retry (with new fuse installed) turning the key to that START position again. If the fuse still blows, there is a short in the wire leading from the “S” terminal of the ignition switch to the 3/8″ nut solenoid terminal.

What causes a fuse to blow on a test light?

The short is bypassing that resistance. With no resistance to limit current flow, that current will be much too high, and the fuse will blow. Your test light or my test bulb has resistance. By sticking that in the circuit where current has to flow through it, the bulb limits current flow to a safe level.

The fuse is the incorrect amperage rating Check what devices or lights are on that circuit, as it may be the case that a new amplifier pulls too much power, causing the fuse to blow. The more devices there are on one circuit, the heavier the amp load. Fuses protect both the wiring and the devices in the vehicle.


What should I do if I Blew my Fuse?
