Speedometer for 115 HP

Not sure how...but I blew the 10 amp fuse on the power connection (red wire inline fuse) to my speedometer. I replaced the fuse, but the guage isn't working. Any thoughts? Tach is still working fine.
Thanks,

Check to see if getting 12 volts through red wire.

Sorry for the delay. Yes I am getting power. Checked it with a meter plus the back light turns on when I turn the key.

I forgot to mention the yellow wire, you should have 12 volts through yellow with key on. If you have power and ground and gauge doesn't come on then gauge is bad.

Yep. I checked both the yellow and the red and have power to both.
