92 acclaim check engine light goes on & off with radio or heater
Hi
My wife's 1992 plymouth acclaim's check engine light is coming on whenever the radio or heater is turned on, It goes out when the radio or heater is turned off. Is it time for a new alternator or does the problem lie elswhere? thanks Dutchie |

Yep. 12: Start of codes 47: Line voltage too low 55: End of codes Go get your battery and your alternator load-tested, and carefully inspect all three topside connections on your battery cables (positive and negative cable terminal clamps on the battery, and the plastic pull-apart connector about 7" downstream from the battery in the positive cable). You will probably need a new battery; yours probably has a dead cell. |

Thanks a lot for the information/advice it is greatly appreciated!
I swapped out the battery with the newer battery from my vehicle ( less than 6 months old). I also cleaned the battery cable terminals. No change. I did notice a few things. With the car idling the alternator/battery gauge sits at 3/4. when I turn on the heater it drops to less than 1/4 and the check gauges light comes on. The next time I do it it stays at 3/4 and no check gauges light. If I keep monkeying around turning on the high beams or the heater it will at some point drop down to less than 1/4 and the check gauges light comes on again. The problem does not seem to be consistent. Tomorrow I will take the alternator in to be tested. Is there anything else I can do in the meantime? Thanks again Dutchie |

The problem does not seem to be consistent. Intermittent problems are always fun to diagnose. Remember to *test and diagnose*, not just throw parts at the problem. > Tomorrow I will take the alternator in to be tested. Have it tested at an auto electrical house -- a starter/alternator place -- not at the parts store. |

Just to let you guys know.
I finally got around to getting the alternator checked and sure enough that was the problem. New alternator and the problem is gone. Thanks for all the input. Very much appreciated Dutchie |
