I have an '87 SDL and am having a problem. The battery/alternator light stays on after the car is started. It never goes out. The light gets brighter as the rpm's increase and dimmer when they decrease. After doing a search on the board I have tried the following:

1. Measured voltage at the battery. It's right at 14V with no accessories on.

2. Cleaned the battery terminals.

3. Replaced the voltage regulator.

The car seems to run fine. No problems with any accessories (headlights, AC, etc.). Is the next step to replace the alternator?

Thanks for your help,
Brian
