I replaced my alternator
on my 2007 w221 s550, my voltage is at 11.7 ob the dash ... i believe i blew the fuse for the alternator but cant find it.. where would the fuse be? I looked online and it says on the passenger side by the starter battery
but i dont see any 200 amp fuses there
JA: Lots of things can cause problems with the battery. The Mercedes Mechanic will know what to do. Are you hoping to fix this yourself?
Customer: Yes.. the new alternator is already in... car voltage remains the same while off and running.. assuming the fuse is blown and not letting the new alternator charge the system so its running on the battery
JA: Great! What have you tried so far?
Customer: Alternator and both batteries are new
JA: Is there anything else important you think the Mercedes Mechanic should know about your Mercedes?
Customer: Its a amg sport package w221 with the nightvision feature... the alternator it requires is a 220 amp not a 180amp
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Mercedes Mechanic about your situation and then connect you two.
