| Post subject: | swap out alternator |
I have an issue with my KK. Two days ago, I started seeing my battery light but the car kept starting. I was thinking it would charge as I drove. Fastforward today. It shut off at a light and the symptoms were similar to a bad starter, just clicking sound when I attempted to start the car. I've tried to jump it with a hand help battery jumper but it just clicks and nothing happens. Any ideas? Battery? Alternator? Starter? Any ideas? |

How old is your battery? If it's more than 3-5 years old, then it might be bad. The battery light signifies low voltage, which usually means the alternator isn't doing its job if the car is running already. If your alternator is functioning properly (making 14+ volts), then there is enough current to keep the car running even if the battery itself is dead. The battery is mostly there for starting the car. Without the alternator providing charge, the battery would run down to the point where it could no longer give spark to the engine or turn the starter motor. Running down like this can kill an older battery as well (had this happen to me once), to the point where it would no longer hold a charge even when jumped. It's possible one or both of the alternator or battery are toast. I wouldn't suspect the starter, especially if you're getting the low voltage light. Have a mechanic at an auto shop check it out. Even a tech at an auto parts store should be able to check the battery and alternator to make sure they are functioning properly. |

Check all the battery connections are clean and tight. Also check the + connection to the TIPM. I had all kinds of strange things happen when I did not get the + wire on the TIPM tight. |

Pop the belt, three bolts right out front and take the alternator off and have it bench tested. You probably have a bad diode. 10 minute job including the first beer. Dave |
