sounds good, I do remember that most of the time the crash sensor is on the battery term, this is just inline. I just picked the car up and I did see it had been bumped and went to a body shop. Car fax does not show it, belts and alt back on but still on ramps. I will fire it up and check voltage at small wire on alternator which I am told is the small wire at the black box. I am in a 1999 slk230k now so this is the wiring PDF I found. I read somewhere that to correct this, you do a jumper between 2 terms in box and it charges. The said the 2 that had 2nd wires which I pointed at in pic. I would think a jumper between the battery and the alternator, what about you guys? I am really in the final hour so BIG thanks for the help, I get it charging I can park it and get on to my bikes that are late to be delivered. OCD sucks!
