[W126 Coupe] Electrical / start problem

[Shin Takei]

Hi all,
Recently my '91 560 SEC has had slow starting. When the ignition is turned on, all the lights in the instrument panel come on and when cranked, it is slow and the wiper turns on without the switch being on.? Then it starts and maintains until the engine is shut off and the same is repeated. All indicator lights including charging turns off when the engine is on. This has been going on for at least two weeks so I checked the battery voltage which reads 12.45 with engine off and 13.65 with engine on. So it can't be the battery and it seems to be charging. Any ideas on what it could be? Some short along the way? dieing regulater?
Thanks to all of you experts.

Shin
