I have searched everywhere for someone or somebody who can find me a replacement siren for my sigma bmw 3t alarm. Tried breakers, sigma dealers, interweb and forums.
The battery from the siren corroded the circuitboard, I think as the battery is showing a proper charge and the siren itself is working so must be a problem with burnt out tracks on the circuitboard.
Can anyone provide me with a compatible replacement siren (new or old) or a fix for the PCB itself.
I am desperate!!
