i know this isnt specifically merc but I presume its common to a lot of alternators
I have a daughter with an Audi A3 2003 with charging fault ....ignition on no battery light and no power at what I assume is excite wire at alternator (2 wire plug) and once started no power output from alternator.
Am I ok giving the excite terminal 12V to kick the alternator in to test its function and is the second wire in the 2 pin plug an earth thatll need connecting to test also,
Assuming the above tests out ok is the battery light excite wire circuit likely to be mired in electronic wizardry, many thanks
