Prelude temp

[Purple]

Hi all,
I wonder if someone with a 3rd gen BA4 Prelude would do me a favor.
I'm having trouble getting the temp gauge to work properly in my '88 BA4 Prelude.
Just need someone to give me a voltage reading from the sender wire. I'm getting 10.5 volts and I'd like to know what it should be.

If you will, just turn on the ignition (don't start the engine), pull the single red wire off the sender (located at the thermostat housing) and measure from the red wire to the battery negative post.

Thanks
Purple
