Yamaha 6Y5-83570-S5-00 Wiring

[Hulk1985]

The readout on my digital multifunction speedometer on my boat recently became barley visible. It was working one day and stopped the next. I was wondering if it could be a wiring issue. I was looking to see if anything came loose and noticed a blue/white wire coming from the speedo that isn't connected to anything. I'm not really sure what it should be connected to and I've had no luck finding a wiring diagram for the model speedo. Any help would be appreciated.

Iv'e heard many times that "fading" of the LCD display is common for these gauges after many hours. Probably don't have a wiring problem. Here's a post from 2005 that may interest you. http://www.yamahaoutboardparts.com/f...es-th3129.html

That's what I'm thinking, it's just that when it first kicks on everything can be seen perfectly and then it almost completely fades out. I'd like to see a wiring diagram to see where the blue/white wire should connect to.

I've seen that link before, my speedo doesn't have the switches in the back so I'm thinking that is a newer model.

Couldn't catch any smaller than 4', need less than 2' to be "edible" and delicious. But did have a nice catch and release off Sebastian, FL.

OP said he wanted to see a wiring diagram for the part number speedometer he has. I posted same.

Oh, I don't see a blue/white wire either.

I try not to get confused as much as I once did. I try to just provide what is being asked for. Even if it makes no sense to moi.

I agree, he is the one that started talking about fish. not sure why he made the other statement either.

where did you get the part # and where is the blue/white wire

are you sure there is not a cover plug with dipswitches behind it?

A little clarification after looking again today....It's a white wire that is connected to a blue wire that connects to nothing. Coming out of the speedo I have yellow, white, black, red and another black. I found the part number by using Google. It basically looks like the S6 model except it has a white back.

Now we have "the rest of the story".

The white wire is for the fuel tank quantity sender. To operate the fuel quantity bars on the speedometer.
