Help Requested on an SL500 Mercedes
I purchased the car at auction during the summer of 2019. I currently have 2 problems that no one can seem to answer. Can you help?:
- The digital clock on the center of the dashboard does not keep accurate time.(runs too slowly). Is there a way to correct this?
- The car has two batteries - the main battery under the hood and the auxiliary/support battery in the trunk. I have 2 battery maintainers, one for each battery. They both have quick disconnect plugs that attach directly to the terminal connectors on each battery. The plugs have a 3 amp in line fuse. The front battery maintainer seems to work fine, but the rear one is constantly blowing a fuse. I've replaced the rear fuse numerous times, but no luck. I don't drive the car during this time of year and recently, I attempted to start the car in my garage. The engine(with the front battery maintainer) started fine. However, there was a display feature which said "Convenience features are temporarily unavailable". I believe it means that the rear battery is not charging, which would be correct, since it continually is blowing the in-line fuse. What am I doing wrong? What can I do to keep this battery charged during the winter months?
Thanks for any information you can provide.
