Hi,

My 1989 300TE is acting up again. Tonight the car ran fine. I finally got the A/C going again and the dealer was nice enought to reset the radio no charge.

Then tonight while idleing at a friends house the car had issues. The a/c was runnng the entire time. The after driving away the ABS light came on, SRS light came on, wipers got slow and the a/c kept kicking down on its own. Did think much until after I went to the mall and came out to find that the car wouldn't start. I then went to the local auto parts store to get a portable jumper, which start the car right away. Then the car acted a bit strangely again. same issues.

I believe that it is the voltage regulator. I came home in the rain and hooked up a meter to the battery and found that with the a/c running and the car on I was only at 11.08 volts. I then went to the trusted 1987 300E parked next to my 300TE and popped the hood and the battery was at 12.57 volts. Had the wife turn the 300E over and the reading was the correct 13.85 or so.

Do you think I'm correct and its the voltage regulator??

Can I change the voltage reugulator while the altenator is still in the car????

thanks for all your time.
