This Friday night I had to get my 1978 300d jump-started. The battery had died, and I have since replaced it. The mysterious and annoying thing is that while trying unsuccessfully to jump-start it, the glow system seems to have been damaged.
The glow light does not come on any more. I can turn the engine over all I want but it will not start. I replace all of the glow plugs about 1 month ago. I tested the glow plugs with my meter, and they seem to be OK.
I immediately tried replacing the fuse for the glow system, but it keeps popping.
Any advice would be appreciated.
