I have 97 ford mercury mystique brand new battery alternator,the light for the ABS comes on which makes the car go slow,battery light come on then turn off,what could be the problem anything with the alternator?
The battery light is actually the charging system light. If it is on, either your battery, alternator, voltage regulator, or some wire or connection in between is not doing what it is supposed to. Could be as simple as a corroded battery terminal connector. You can have your battery and alternator tested for free at most auto parts stores. The ABS light comes on when there is a fault with your antilock braking system. When the light is on, it means your ABS is turned off because of one of many possible issues. One of those issues could be low battery power to the ABS controller, so the charging system issue you have could be causing both. The ABS light in no way can make your car go slow. But. A bad battery connection would prevent the alternator from properly charging the battery, and when the voltage at the battery comes up low, the alternator kicks in and tries to charge it which does put a draw on the engine. Wiggle the battery connections, they should not move. Clean the battery terminals and connectors. Make sure the main (normally) red wire on th ealternator is tight. Make sure the other - normally a clip on connector is plugged in. Go see a mechanic. Good luck
