Bulbs in center assembly on dash

[dsagona]

Hi,

Other than the bulbs that are clearly labeled, and someone tell me what the other indicator bulbs are for? I know one is for overdrive, but I’m not sure what the others are for. I’m replacing the bulbs and need a way to test if they’re working. (I know I’m missing one bulb at the top.)

Thanks!

Take a bulb out and shine a light through each one?

Probably PWR, O/D OFF, and 2nd Start

Good call on using a light. I tried doing that on the top hole over the weekend but I didn’t see anything, so I gave up on the others. It turns out the top one is blank, but the bottom three are od off, power, and 2nd start.

The filament might be too small to see. Ohm out the bulb- if there's continuity, it's good.
