Buzzer alarm wiring

[Dpearce]

Anyone have a schematics for the wiring of the buzzer alarm for 2010 Tahoe q5i with a 4.3 or know how the buzzer is wired in. Thanks

A lot of those 4.3 motors have buzzers for low oil pressure or overheat. I believe the sensors for both system ground their wires to the block.

The sender for oil pressure to the gauge is separate from the low oil pressure sensor.

Some of those 4.3 also have a sender for water temp, separate from the buzzer sender. Look on the thermostat cover for both of those.

What problem are you having?
What motor is in the boat?

One side of the alarm is connected to 12V when key is ON, and the other will go to the ECM

Boat is carbureted. No ECM 4.3 V6

Buzzer was unhooked I'm trying to install it back the way it goes

Depending on which carb (regular or TKS) then the alarm is connected to the purple wire coming from the key switch. When key is ON it powers one side of the alarm.

The other side of the alarm is attached to a Tan/Blue wire which is connected to the temp switch on the thermostat housing, the oil pressure switch by the oil filter and the outdrive gear lube bottle. If anyone of the 3 activates, they will close their switch contacts and apply a ground which turns on the alarm

The pic is for 2 and 4 bbl carb V6 with TBV ignitioon. In block "C" items 1, 2 and 3 are the 3 switch previously mentioned
