1998 Mercury Grand Marquis Q&A
1998 Mercury Grand Marquis Question: What causes my voltage to spike on hard acceleration? Bad voltage regulator?
My interior lights, radio and climate control all shutdown when the voltage spikes. As the RPM of the engine returns to the normal range, the everything usually works properly. Sometimes the ABS light stays on, but will reset when the car is turned off and back on. - MRChodan
