location of external voltage regulator, 280SE 4.5
I need to replace the voltage regulator in my 280SE 4.5, which has a Bosch AL72X alternator. This model of alternator does not have the voltage regulator mounted on the back. It has a three-prong round plug with wires leading... somewhere under the battery tray.
So I need to find out the exact location of the external voltage regulator. Other posts say it's on the right front fender; this appears to the the case for 6 cylinder W108 models, but not for the 4.5. All I see on the right fender, near the firewall, are two electrical relays in a single frame (they don't look like the part in question).
Can someone pinpoint the regulator for me? (Photo if possible?)
(It's not the case that the Bosch alternator has the voltage regulator built into it, is it?)
