Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
for the brake light looking at your master cylinder is there a two wire plug on the reservoir? and for the battery light after alternator replacement or before did you measure charging voltage?
the maf sensor is giving a bad signal to the ecm and causing it to idle up. the voltage is a bit high and high voltage can cause a light aswell. do the lights go out when the maf and map are unplugged out only the alt?
was the brake and battery light on before replacing the alternator?
what do you disconnect on the alt? the main battery or the plug? also does it idle down when you do this or only wen the maf sensor is u plugged.. also do the maf and map have to be unplugged togetheror just one?
so you will want to replace the maf and it sounds like the alternators internal regulator is bad. im guessing since you just replaced it you should be able to exchange it.
that still indicates a failed alternator regulator with the alt unplugged it should not charge since the regulator wont cite it.
