Questions on main gauges/tachometer
« on: November 16, 2022, 02:35:44 »
1) Circled on the back of the tacho, is that another bulb in there (circled?  If so, Do I just pry that out?

2) how hard is it to get the chrome bezel off?

On the chrome bezel, I think the trick is to do it slowly and carefully, only prying small bits at a time.

The brown wire goes to the center peg with the knurled knob.

A blue wire goes to one bulb, and then also to the post circled as aforementioned

I believe that is an extra light, not 100% sure though.
