Ic Regulator
WARNING: This page is about a different car, the 1998 Acura SLX. However, it is still accessible from the selected car via links, so may be relevant.
Use DVOM to check continuity between IC regulator terminals "B" and "F". See Fig 1. Note DVOM reading. Reverse leads, and repeat test. Continuity should only be present in one direction. If continuity is indicated in both directions or not in either direction, replace IC regulator assembly.
