Can a bad starter blow ignition fuse?
Can a bad starter blow ignition fuse?
If your ignition system shares a common circuit with something motorized — a fuel pump, cooling fans, power window motor, starter, etc. This can easily blow a fuse, particularly if it’s already heavily loaded by something as power-hungry as the ignition system.
What causes ignition fuse to blow on start?
If it is the contact side that is failing it is a starter drawing a lot of current. Check the battery feed to the starter motor for a bad connection, the relay is only supposed to pull the starter contact in and the big cable supplies the actual starting current. If the battery feed is dirty/blown, the relay carries the load.
What should I do if my starter fuse blows?
Check the battery feed to the starter motor for a bad connection, the relay is only supposed to pull the starter contact in and the big cable supplies the actual starting current. If the battery feed is dirty/blown, the relay carries the load.

If the WHITE wire coming off terminal “S” is shorted anywhere between the ignition switch and the clutch/brake switch and the attachment clutch and solenoid it will cause the fuse to open/fail or if “clutch/brake switch or “attachment switch is shorted it will cause the fuse to fail/open whenever the key is turned to the start position.

What causes a fuse to short on a starter solenoid?
A look at a schematic shows this fuse (No. 8, 20 amp, hot all the time) provides power for for the starter solenoid through a separate starter relay. The problem should be one of 3 things. Intermittent short in the red wire to the relay or in the brown wire to the starter solenoid. Internal problem in the solenoid. Faulty starter relay.
What to do if fuel pump fuse keeps blowing?
To determine which circuit is the troublesome one, unplug the fuel pump relay, put a fresh fuse in the #8 slot and turn the key to start the car. If the car turns over, you most likely need a new fuel pump.
