I have the plans to convert my alarm buzzer over to - ground but the Radio Shack pt# RS 1114 must be an old #. They had 2 that I thought might work but wasn't sure, a 12v one and a rectifier one. since the diodes take the place of the rectifier is that the one I need?

hope I'm following you correctly on this...I just changed my low air buzzer over to a strobe light & found out that on my Eagle one wire on the buzzer was always hot & as the system got air pressure ...ya' loose your ground...which makes the buzzer/light ..stop

I'm converting the whole electrical system from + ground to - ground. The warning buzzer is a small part of it. The buzzer is fed through an old rectifier that can't be reused. It has 4 wires (I think) coming out of it that needs a diode between each wire and the + side so it will work. I think it does more than just a low air warning, hence the 4 wires.

If I remember correctly, the 4 wires are oil pressure,air pressure coolant temp & rear escape door(open).

Two Dogs, it's different than the Eagle 'cause the one buzzer buzzes from any one or more of the items.
The system also lights dash lights for each item, that's why the diodes are needed. Actually, I think you could use 4 cube relays instead.
