Armature Coil Test
WARNING: This page is about a different car, the 1999 Acura 3.0CL and 1999 Acura 2.3CL. However, it is still accessible from the selected car via links, so may be relevant.
Using an ohmmeter, check for continuity between commutator and armature coil core. Check for continuity between armature shaft and armature coil core. If continuity exists, replace armature. Using a growler, check armature for shorts. If continuity does not exist, replace armature.
