Tach swap now guage lights don't work?

[kayinsunz]

So, let me start off by saying that classiczcars.com is by far the most helpful, accurate Z Car website by far.

 

Thanks to a write up by BlueisNow, I was easily able to swap the internals from a 280z tach into a 240z tach and now my tach reads PERFECTLY! Big up to the man like that..

So, now that I've swapped it, the backlighting will not turn on, neither will the blinker lights.

Any of you fine gentlemen ever experienced this before? 

 

Thanks for reading,

Make sure the gauge body is in firm contact with the chassis. If you were testing the gauge without having securely mounted it in place, it would not have the ground for the lights. If you did have it attached with screws, examine the gauge and dash mounting points for rust or other debris that would insulate the gauge body from the dash.

Once again, classiczcars to the rescue. 

Worked great. Thanks for the input!
