Need Schematic Diagram for 78 Buzzer Module
Can someone post a schematic diagram for the buzzer module for a 78? I'm going to try and trouble shoot mine since these parts aren't available anymore. Thx in advance.

I'm in the same boat...have collected about a half dozen of these buzzer units and have taken them apart. I have the factory schematic but it shows the buzzer as a box or unit and how it connects to the other buzzer components. Drop me your email address and I'll send.

yeah hunt, i have that algorithm too. We need a schematic diagram of the printed circuit board. In my case, the buzzer is staying on for several minutes before timing out. Anybody know what components usually fail and/or cause this? Thx.

Ok, I've invited Wilcox, (premium supporter) over to this thread and ask for his help. He's been great with the tach board stuff so perhaps he can help with this.
I have a 77 buzzer but the buzzer tone is different than a 78 and it was a first design.

Dar... Nope, I don't have one, but were going to take one apart and see what we can come up with. I have added this to our project list and it's behind the new tach boards and the wiper modules.
Maybe someone will have one, but I don't.... yet.
