Car Forum / Kia Cars / September 2006Warning Lights for Charging System & Brake
As of late, my battery has being going dead while I'm driving. In an effort to track down the problem (battery or charging system), I starting paying closer attention to the Charging System warning light in the instrument cluster only to realize that it does not work. With the key on but before starting, neither it nor the Brake warning light illuminate. The Oil Pressure warning light works fine. I swapped bulbs around and found no problem with them. I checked fuses but am unsure which one applies. Any thoughts on what I need to do to fix this (or what fuse I specifically need to examine)? -- Christian 2002 Kia Sedona EX 3.5L > As of late, my battery has being going dead while I'm driving.

With the engine running what does a voltmeter read at the battery terminals? Anything less than 12.6 volts would mean your charging system is not working.

This would account for the battery drain but does it explain the non-functioning warning lights? -- Christian > Hey Chris, > [quoted text clipped - 3 lines] > > -- Christian If you confirmed the bulb is good then what you probably have is a failed voltage regulator. They can go bad in such a way as to put a drain on the battery even with the car off. Chris >If you confirmed the bulb is good then what you probably have is a >failed voltage regulator.

Should I just replace the entire alternator? I tested across battery posts with the car running and found 11.5V so there's definitely no charge going in. -- Christian > As of late, my battery has being going dead while I'm driving.

Both are routed through Connector block 'C' . pin 3 is Brake warning light, and pin 4 is Ignition light. Gordon >Hello >I looked up the connection to Brake & Ign lights.

I just need to take a look and either rule it out or replace it. -- Christian >>Hello >>I looked up the connection to Brake & Ign lights.

I think! Gordon >>>Hello >>>I looked up the connection to Brake & Ign lights.

If I get this fixed, I'll let you know. -- Christian
