What causes the ignition fuse to keep blowing?
The starter can also cause this to blow. If the starter is failing, especially the starter solenoid, a power surge may be being sent to the fuse and blowing it. You can have your starter bench tested, but they wont test if the starter is powerful enough to actually turn over the engine. It only tests if the starter will spin.
Why does my Mitsubishi starter keep blowing fuse?
You can have your starter bench tested, but they wont test if the starter is powerful enough to actually turn over the engine. It only tests if the starter will spin. The fuse is being sent a current that is too strong for it, and you need to find what is sending that signal.
What causes the ignition to shut off so fast?
Situations occur when there becomes corrosion inside of the ignition relay. This can cause the connection area inside the relay to become too small – which will cause the ignition to shut off and on super fast.
Why are the fuses blowing on my computer?
Inspect your wires carefully; hot parts on the engine can easily burn through the wiring’s insulation and short the wires, and metal edges will cut through the wires and short them out. If you’ve got fuel injection, then you might be experiencing an internal short in the computer itself.
What causes a fuse to blow on an ignition switch?
The good news is that there aren’t too many things in the ignition system itself that can blow your fuse, particularly if the the ignition coil draws its current directly from the battery or alternator via a relay. If that’s the case, then your fault is almost certainly in the ignition switch itself or the wires going to it.
What should I do if I have a bad ignition relay?
Remove the ignition relay from the fuse box. Get a couple of cables and locate the car battery. Check the relay’s backside for numbers; you will probably find 30, 85, 86, and 87. Remove the relay from the fuse box. Connect 12 volts from the car battery directly to the pins 30 and 85.

What happens when you turn off the ignition key?
When you switch off the ignition key, the ignition relay should also shut off power to all engine components; otherwise, it will drain the car battery when you let the car stands over the night. When the ignition relay fails, it can cause the ignition system to be activated constantly, even when you have removed the keys from the ignition.
