Hello all,

My brother has a 94 Cherokee 4.0 4x4 5spd. His ignition has gotten to the point that sometimes you have to turn the key all the way back into the aux position and then turn to start it. It also acts like you have to put all of your body into turning the key.

Also the alternator is acting funny...driving normally and it will drop down to almost 9 volts on the gauge, then the check engine light will come on. Some times when the volts drop the A/C will go from cold to just blowing outside air. The check engine light doesn't stay on all the time comes and goes when it wants. The performance doesn't appear to be affected by the volts dropping, just replaced the brushes about 6 months ago.

Don't know what to check and what to just replace???
