14.6 means your voltage regulator or diode is suspect Despite having new alternator .Ive cross refrenced your smptoms in the haynes workshop manual and alternator is your only end answer.The haynes test is to start vehicle with multi meter connected across the battery terminals,increase the engine speed until the reading remains steady should be approximately 12 to 13v and no more than 14v.switch on as many accessories as possible(headlights heater blower radio etc)check that the alternator maintains the regulated voltage at around 13 to 14v.If the regulated voltage is not as stated then alternator is to be repaired/replaced.Good luck with it and a happy new year.

There are many emission sensors in the car that will make the engine light come ON. Not to mention the big list of trouble codes for the engine light. The engine light code will give you a big clue of what's causing the accelerator pedal problem.


Best way to find out what's going on engine light is to have an auto-parts store hook up a engine code reader and tell you what the code means and the problem. Most auto-part store will do this for free.

This dosen't help but.........
I have a similar problem. Every 4 weeks or so the car refuses to start. Again battery is not a problem but if we use cables to jump start from another car it starts fine.
Mitubishi cannot find the answer, only suggestion was to spend £150 on a new key , however the problem has now occured with both of the keys !

SOURCE: The battery keeps going dead on 1999 Mitsubishi

There is an alternator fuse located on the positive battery clamp or in the fuse block under the hood. if it is part of the positive battery clamp it is a dealer only part and will run $10 to 20 dollars. If it is in the fuse block you should be able to get one at the auto store and modify it to slide in easily. Get a flash light and check all of your fuses carefully. The blown fuse may be hard to spot. The design of the car lets the battery go dead with out even turning on the charge light on the dash to let you know you are not charging the battery.

Your alternator is out. Those are classic symptoms of alternating going out. The alternator recharges your electrical system and when it goes out a list of strange things go on inside the dash, and you won't be able to go very far on just a battery. I'm glad you at least made it home. But yes you will need a new alternator for sure. Please rate this response so I can get my ratings back up to 90% at least.
