Fuel gauge won’t go into calibration mode

[vette57]

I’ve got the vintage gauges and the fuel gauge will not enter calibration mode when I depress the button for 10”-12”. Any thoughts on what to try?

Do you have a bad push button unit? Historically, they've been prone to failure. To test, try plugging the push button into a different gauge & see if it works.

If the button passes, the I'd call Speedhut & see what they recommend. They're customer service is outstanding.

The gauge has to be powered when calibrating. Check power at the gauge. Do you see that gauge needle sweep when yo turn the key to the on position?

Yes there is power to the gauge. I’ll text the button next to see if that is the problem.
Thanks you guys for the help.
