Batery light would come on when accelerating up to freeway speed or when going over a big hill and head lights would dim. Mechanic said alt/gen/bat all good, car still seemed to drive fine otherwise. Battery light came on constant the other day and the car had a huge power drain and once turned off wouldn't restart. Any suggestions?

got DRL? lamps, daylight running lamps ? like they do up in Canada?
dash charge (gen, battery) warning lamp glowing"
if yes the fan belt fell off or Alternator gen, is dead.
the Alternator , runs power with engine running not the car battery
when Alt GOES DEAD, BATTERY DRAINS FAST AND IN 1HOUR
OR LESS ENGINE DIES, (PCM dies about 10vdc at battery weak)
or bad head lamp wiring, or bad DRL.

Repair your vehicle right away. Just click on the link I attached 2001 2003 Mitsubishi Lancer Evolution 7 EVO VII Service Repair Workshop...

the p38 is a bit sluggish and slow on long steep hills, really not geared for performance but more as a piece of heavy equipment. strong horsepower wise very formidable powertrain but you're not going to have that get up and go that many drivers look for. couple quick suggestions you may want to check your plugs and wires a common weak spot in the ignition system, and i might suggest also running i can of seafoam through your engine. you deposit in your gas tank runs through with the half a tank of gas. i'm not a big advocate of fuel additives or octane boosters but in the case of seafoam it's definitely a worthwhile and proven product. don't forget also your sport mode button down next to your shift lever push that button down and it keeps your transmission from overdrive so you can accelerate into freeway traffic and climb hills without your transmission shifting

All the above problems were happening to my truck, and the engine light never did come on. Finally changed the O2 sensor, and it runs like new again.

Hi Jon Jon, Did you also replace the spark plug? Changing all would be a good idea. Regards John

replace your altenator . the brushings are most likely bad and only making contact after you strick the alt. housing. it makes the brushing drop down to the armature.

Lots of stuff. An after market alarm,malfuntioning radio,bad battery,bad door pin switch for the interior lights. Best thing to do is charge the battery if it's in fact good, thenunhook the negative battery cable & connect a test light from the disconnected cable to the negative battery post. If it's a nice bright light it's got a draw. If it's really dim,that's the memory for the computer,anti-theft,radio memory. I mean dim,like barely lit! That's ok. If you don't have a test light disconnect the negative cable & touch it to the negative battery post a few times & if there's a big spark,there's a draw. If there's a draw & there's nothing on in the car,like an interior light,etc, than start with the inside the car fuse box & while holding the open door pin switch test each fuse for power. If anything has power that shouldn't with the key off that's where to start. Do the same for the under the hood box as well but disconnect the hood light. If you are using the Viper alarm system,junk the system. That alarm causes your problem & in alot of cases a fire.

Hi, two possible issues here. the first could be a malfunctioning shift solenoid. this can affect the shifting operation. the next issue could be the transmission control model(TCM). if this fails, you will experience abnormal shifting during up and downshifting. I would check these areas as well as the fluid level as well. Some transmissions are sealed and you cant check the fluid level. if you have a transmission dip stick visible, please check the fluid level before you check the other areas.

please rate and god bless.

Replace the alternator if it's output is too low the gen light will come on,could also be loose or dirty connections at alt amd bat
