1999 Mitsubishi Eclipse Repair Question
Mitsubishi Eclipse Battery Problem
The battery may have a full charge but is not capable of providing full voltage when under a load. This is usually due to a bad cell. You can take your battery to Advance Auto or Auto Zone and they will load test it for free. Also, your alternator may not be working properly and not charging the battery to 12 volts. That may be the aqeaking sound you hear. Grab the alternator pully and feel if there is any play in it as the bearings may be bad.
