Gauges not working

I've got a 2000 Mastercraft 205V. It runs like a dream, but I'm some of my gauges don't work (Engine temp, oil pressure, and fuel) I've pulled the dash and i'm trying to figure out if its the gauges themselves or the wiring.

The engine temp for example has 4 wires going to it.

red with white stripe (i think it's positive)
Black with yellow stripe (I think it's ground)
yellow ( my guess is the voltage from the temp sensor)
blue (think it's the 12v for the light in the gauge)

Does anyone know what the voltage range the wire from the temp sensor should have for the gauge to work properly? Or for the oil pressure, or fuel?

Don't know that boat. Does it have breakers on the dash and are any tripped?

Commonalities would seem to be power?

I should also mention that none of these gauges move at all when I turn the key on

Manual for your boat is available here
http://www.mastercraft.com/files/man...s%20Manual.pdf

Breakers -says they are under dash - push each one in.

Fuse - might be one by battery - replace it.

Report back after -

Having several gauges each with different sending units (fuel tank/temp/pressure are all different switches) makes it highly unlikely it is anything other than a breaker/fuse.

Ok more info. I put a new MDC in last year because it had water in it from the year before.

I pressed all the fuses below the dash and none seemed to be tripped

I was wrong, the Fuel gauge does move. It goes from 0 to max as soon as the key is turned on
Oil pressure just flickers a little bit and does not move
Temp flickers a little bit and does not move
Voltage seems to work properly. It comes up to a little less than 13 when the key is turned on.


I moved the gauges around and plugged them into different spots and they all performed the exact same way no matter where I plugged them in. Now I'm thinking it might be the gauges????

Does the light work? If none of them work, it sounds like a bad ground wire. Try running a jumper wire from the engine block to one of the ground posts on a gauge and see if it comes to life.

I guess it's probably not worth fixing. You better just trade me for my tristar. Everything works on it! Lol

I'm in Fort Smith, AR. The boat had an Indiana title.

The backlights in them do work, but its not a series ground like the gauges that have the posts on them
