I have a problem with my My 1975 Mercedes 450sl.
I don't drive it that much, but due to an accident, I am forced to drive it. After a couple of months, I started my car and found to be sluggish, but did start. (I attributed that to the fact that it sat for a bit and it was cold) I drove it to a friend's house and when I returned to the car it wouldn't start. I charged it and it started and I drove it home. It sat for 2 weeks. Last week, I attempted to start it and there was nothing, but a short hum, which lasted only a few seconds, then nothing. I replaced the battery, but it still won't start. (only the humming sound) The red ignition light is on and all the electrical works, so I am perplexed.
Any thoughts or ideas?
