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.
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.
How often do you get a blown fuse?
Most people probably have experienced a blown fuse at one time or another. Someone always knows what to do when this happens. If you’re a homeowner, that person probably is you. Blown fuses are a common occurrence.
Why does my car keep blowing the fuse?
Now it is back to blowing intermittently. They think it might be the starter but are not sure. After getting the car to start once with a 25 amp fuse (vs. the called for 20) it started each time for them with the 20 amp back in place so it is hard to be sure.

What does it mean when a fuse is blown?
Yet people commonly use the expression “blown fuse” to describe just about any unexpected electricity-related occurrence, especially one involving a loss of power. A “blown fuse” can mean many different things–several of which have little to do with actual fuses.
What should I do if I Blew my Fuse?
The Fix: Make sure the faulty device is unplugged and there is no damage to the outlet. First, test the circuit. Then check for any damage on or around the electrical panel. If you see any damage, call an electrician before doing anything else with it. If there is none, flip the breaker switch back to its operating position.
Can a 15 amp starter fuse be blown?
Fifteen amps may not be enough to blow the fuse on a one time deal but this repeated current surge due to the fan cycling on and off can weaken the fuse and eventually pop it due to heat.
Why does my Car start with 20 amp?
They think it might be the starter but are not sure. After getting the car to start once with a 25 amp fuse (vs. the called for 20) it started each time for them with the 20 amp back in place so it is hard to be sure. The questions are 1) Does this seem like it could be the starter or if not what might it be?
How many amps does a good car fan draw?
An inductive ammeter could also be used to check the fan current draw when it is running. The important part here could be the current surge when the fan first starts. A good fan may draw 4 or 5 amps and a worn fan could draw 8-9 amps during normal running.
