Wiring Diagram Symbol

[LDUBS]

This is my outboard's wiring diagram for gauges. Does anyone know what these symbols mean (red arrows)? Thanks.

Those are either splices or single wire plugs. The dotted boxes are separate wire harness and splice/plug connects them together.

Each manufacturer may use slightly different symbols, but those look like single wire plugs.

Attached is a Suzuki single wire plug with plug caps installed. Triangle side is the male plug and rectangle is the female receptacle.

Guys, you are dead bang on. Many thanks.

InSaneFisherman, they do in fact make a harness that runs between the gauges and the side mounted control box. It uses single wire bullet plugs.

Next step is to get my hands on a tach.

Most of the analog tachometers are programmable and set to the number of poles in the flywheel.

Make sure you get one that is made for your engine or it has plenty of program settings.

Sierra has a whole line of nice aftermarket gauges, in different color schemes. I have the Eclipse tach and water pressure gauge, will likely add a temperature or oil pressure gauge in the future. The tachs are fully adjustable to whatever pole setup you need.

Wiring them is really pretty simple, the tach just needs switched power and ground and the signal wire (the grey one in your diagram). The rest will likely be all mechanical and only need power/ground for the lighting.

They are bullet connectors, the arrow is the male end (uninsulated) it is normally not powered until plugged in

Monday at 2:21 PM posting of that red arrow is the symbol used to indicate a DIODE.
It is used for any type of logic in controls. They can be inserted in a wire with just shrink wrap around them. Some are used across D C current relays to prevent surges from damaging computer switches. They are also used in safety circuits F N R contacts can also use them. They are used for logic and protection in many boat circuits.
They allow current to ONLY flow in 1 direction.

Disagree, there are no diodes in the schematic posted with the original question.

You're both correct, post #3 shows a diode and the original post doesn't. Now if you want to get picky about it the post was made at 1:21, ha ha ha.

Dale's post is a link to bullet connectors. The enginnering group or page use a diode as its logo, that's the only reason it is displayed. The logo has nothing to do with the original question.

Correct

I ended up getting a decent deal on the Sierra Eclipse tach. I'm going to make my own wiring harness. While I'm at it I think I will reorganize the wiring under the console. I was sourcing some heat shrink connectors. They sure don't give those things away - Yikes!
