Contour Enthusiasts Group Archives Forums General Troubleshooting Battery Light Flashing off Idle

Sorry for delay, that was not a long lunch, computer froze up when proof-reading my post and I had to re-boot and start from scratch.

I have thought about your problem and have a strong feeling its the alternator. Here's a quick check, when you get the pulsing on clock turn on either dome light or vanity mirror light and see if they pulse too. If so, then I believe your bat light is telling the truth, i.e., something wrong with alt.

I have avoided further diagnostics on alt since you paid for problem to be fixed and they should fix it right. My suspicion is alt regulator or diode (both internal) and that alt is putting out some amps. When heavy load (headlights) applied battery smooths volts but on light load (clock illum.) fluctuations show up.

Pls try above and we'll keep an eye for your next post
