What causes a fuse to short on a starter solenoid?
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 does a 20 amp starter fuse do?
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.
Can a worn starter motor cause a fuse to blow?
If one was looking for the easiest and cheapest way out then the relay could be changed to see what happens. Tracking a wiring short is a bit more difficult and if the starter solenoid were replaced then it should be changed in conjunction with the starter motor since a worn starter motor can wear out the solenoid.
Can a worn starter motor wear out a relay?
Tracking a wiring short is a bit more difficult and if the starter solenoid were replaced then it should be changed in conjunction with the starter motor since a worn starter motor can wear out the solenoid. It will not wear out the previously mentioned relay though.
What causes the fuse to blow on a starter?
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. (This could be caused by burned contact points in the relay.

What happens when you blow the 20 amp fuse?
The 12 volts power supply from that 20 amp fuse is distributed to more circuits than the start circuit. The electrical short / overload could be in any of those branches. When power branches like this, the branches have to be checked and disconnected to find the fault. Good luck in finding an electrician. It might be worth changing the starter.
