Re: Knocking sound -electrical problem?
It could be the drive gears for the alternator. They are supposed to be set up at the factory for a specific amount of clearance. There are three different sized gears available to set this. It is a BIG job to tear down the rear of the engine to measure this, and more work to replace the intermediate shaft with one of a different size.
There is another possible cause, which I had. Broken exhaust header pipes where they are welded into the flanges that bolt into the head. Mine had a pronounced rattle at low RPM, and it took me a long time to narrow it down and find the problem. Welded them back and no more rattle.
There have also been several breaks in the welding between the catalytic converter and muffler section of the exhaust. I also had this happen, again re-welded.
I don't want to achieve immortality through my work...I want to achieve it through not dying.
