Question: Dear sir,
95 mitsubishi GSX 5-Speed
modded:
-air intake
-suspension
NOTES:
-no stereo *all wires taped up.
i have been having problems with my ignition system. for some reason, when turning my ignition switch to the "ON" position, my car blows a fuse. the fuse that keeps blowing is the 30Amp fuse located inside the engine bay near the cold air intake. the wire that is affected is the Black/White wire connected to the ignition. i traced it to a fuse box which it enters and then exits in the rear. from the rear, i traced it to the firewall and from there, it dissappears. strange. i have a manual i bought from the dealer. any advice on how to BYPASS this ignition wire would be great, or how to fix it. Please let me know what i can do. Maybe there is a bad groud wire somewhere connected with the ignition system that i can troubleshoot. thanks.
Answer:

Kong,
I believe the fuse you are referring to is the ignition fuse or the MPI fuse. That fuse may be blowing because of a bad ground. If that's the case, use the manual you bought from the dealership to trace all connection points for correct voltage readings. Another reason why that fuse may be blowning is because something is malfunctioning. That fuse can blow if the alternator is bad and a capacitor inside has melted. Alternators typically go bad after 8 - 10 years. I have also had that fuse blow out me when my fuel pump was malfunctioning. When my fuel pump died, the car's computer detected the potential risk and automatically blew the fuse. There is a procedure in your manual for checking your fuel pump.

If you're really deadset on BYPASSing the fuse, which I HIGHLY DISCOURAGE, is to simply run a high (thick) gauge wire across the terminals where the fuse sits. The is highly dangerous, especially if there is a problem. The risks could be anything from melted fuse box, to a car fire, or even death. Find the problem by whatever means, and do not try to bypass that fuse. 30AMPs is an enormous amount of power and is quite deadly if not under the control of a fuse.
Good luck!
