Have Mercedes Questions? Ask a Mechanic for Answers ASAP
I use a jump box and hook the timing light to it. you could also hook it to a battery charger for the 12v needed to operate it.
There is but not sure it I have the wiring diagram to tell you which one, but let me check. If you have a voltmeter, you can check for the wire with 13.5v to 14.7v on it and that goes up and down slightly if you rev the engine. That will be the hot wire going from the alternator to the battery. I will check to see if I have the wiring diagram of it though
I have gone thru all my sources and do not have one for it

Ok, sounds good
Ok, I am out of ideas on this one and will opt out and open it back to other experts to see if they know
