95 Seadoo tach and multi guage not working

[ihavenoideawhattoput]

OK, I have checked all the fuses I can locate, I have grounded the tach to the battery and traced wires till my head hurts. Ran diagnostics and got nothing.

What is supposed to happen after plugging in the lanyard, anything, gas guage, lights, beeps?

VTS guage works and functions just fine.

I have searched and searched for ever with no luck.

Here are the guages.

The Top and the bottom one do nothing. and before you say anything about what they are installed in, they did not work when they where on the seadoo before being removed.

Non working guages are not an issue I just like everything to work and I am hoping this is a simple fix.

The muti-function gas/oil gauge powers the other two, if ya look at the wire diagram
in last pages of the Shop Manual. In the electrical section are test prosedures for
checking the gauge. Bill
