Hi,
I have an issue with my 1982 300D not starting. It has a brand new battery which when I tested is holding 12V. I tested the posts while disconnected from the car and it shows 12V. However when I jumped the car to get it started - the car runs fine - then when I goto start it again the JUICE is low. The thing is when I drive it around a bit it will start again but once left for a long period something appears to be draining it. Though the Battery still registered 12V.
The thing that is leading me to the PREGLOW TIMER, is when the car is turned off I am getting a fairly loud buzzing sound from that TIMER RELAY. It will buzz until it is barely heard and then seems to shut down. (Basically seems like it buzzes with the car off until it buzzes no more.)
I noticed someone on this forum that had a similar battery problem and someone suggested taking the BIG PLUG off of the Timer Relay and trying to start the car and see if it holds a charge. IS THIS THE BEST THING TO DO FROM MY STANDPOINT ? What do you recommend ? I don't want to buy a timer relay unless I know for sure ($150 part). The battery is brand new, and if jump started the car runs with all electrical elements working radio, lights heater etc ... However when running if I have the heater and lights on at the same time the radio will Dim.
This is all new, ** could it be the alt. belt (like the other fellow found out ?? ) or the Timer Relay that is buzzing unusually ??
Thank you
