Hi to everybody! Can you please xplain me working priciple of S2 lock sylinder heating modules. I bought these modules with harness and etc. from other S2 that was dismantled for spare parts. Here are some pics to explain:
Before installing these modules i connected heating element and micro swich to their socets, +30v pin and ground pin connected to battery for testing. Nothing happened, lock sylinder did´t heat up. Tryed to push and hold swick and test button but the result was the same, heating element still cold.
Then i disconnected the heating element, connected multimeter to heating element pins and repeated the procedure. Result was 0,0V DC current. Also tryed to connect swich pins straight with each othen in case the swich was faulty but stil lno effect.
After that i connected the multimeter straight to the disconnected heating element and tryed to measure impediment. Result is as shown in the link below:
Funny thing is that former owner of this system said that this stuff worked on the dismantled car before. Any ideas how to get it working? Maybe these black modules are´t woking properly?
