1991 500SL getting an electrical battery drain on SL . Installed new Mb battery. Tested each fuse with hella electrical tester. Cannot isolate where short is coming from. Has a factory installed Becker silver stone CD player that was blinking in the truck as if it was searching for cd. I disconnected the 3 wires coming from CD player. Also convertible top button just blinks red when I try to unlock the hardtop. Any suggestions appreciated.
Instrument cluster clock is not working but everything else on cluster works.
