OK everyone . . .

I just bought a really good voltmeter and finally got around to testing the chrage on the 300SE.

Here is the step-by-step testing that I did:

- I have the fans set to full blast
- I drive until the fans quit.
- I slow down to stop the car
- As the car approaches the stop, the fans increase in speed
- The car is stopped and the fans are now blowing hard
- I pop the car in neutral, causing engine RPMS to increase by about 300 and the fans stop
- I check the voltage -- 14.2Volts
- I put the car in drive, RPMs drop 300, and fans start blasting again
- I check the voltage -- 13.8Volts
- I put the car in neutral again, engine RPMs increase, fans die
- I check the voltage -- 14.2 Volts
- Now, with the car in neutral and the RPMs still 300 higher, I turn on the heated seats, rear defrost, lights etc. Meanwhile, I am reading the voltage at the battery at the same time
- Voltage drops to about 12.8 Volts
- The fans start blasting

So it seems like, when the voltage is about 14V, the fans don't work. When the voltage is below 14V, the fans work. I therefore think that the voltage regulator is my problem.

Does anyone see an error in my logic? Should I go ahead and order a voltage regulator?

Thanks for your help guys!
