Hello since my calibra has been standing for a while now and I haven’t found the fighter yet I wanted to ask again if the calibra has an overvoltage protection relay or something like that. my calibra just went out some time ago during the ride and then had briefly lit up the battery lamp and then it slowly became darker and then did nothing more. no check-ups and it no longer runs. the ventilation and the interior lighting still work. the sliding roof radio and window lifter no longer work. can it be related to a relay? have seen through the securings in the footroom so far and those were all okay. has the calibra secured somewhere further? have a calibra 2,0 8v c20ne build year 09/1993 please help.
