What is the piece above the buzzer? It can’t be a relay with only 3 wires?

With key on. I have 12v coming into it. But not going to buzzer.

Buzzer no longer works with key on. So it’s probably the top piece.

Thanks.

Welcome aboard. Sorry I can’t help with that.
 
Sure it can be a relay with 3 wires ! Let me know if you want me to send a sketch of how it would work.
Regards,
Nick

The buzzer is grounded though. I have 12v on both incoming wires blue abs red. . And nothing leaving to the buzzer on the black. . I’m thinking it’s more like a diode pair for 2 different alarm inputs and either 12v should pass though. That pic was the good engine that works. Has 12v On the black output to buzzer. The non working one looks way worse and is totally rusted.

Was hoping someone knew exactly or had a part number. Most old gbs have this setup.
