Help with gauge wiring

[Allen Gasper]

I just got my gauges back from the repair shop and noticed how the indications on the back do not match the schematic. I think I can pretty much figure it out, but would like someone to confirm. Everything has the factory designated numbers/letters next to it with my Sharpie marker translation. Can anyone confirm? Also, what the heck is the lone black wire for? I know the top right hand terminal marked "G" is for the fuel sender.

Lastly, the speedo has two terminals on the back, not just one - what are they for? One for back-light and one for the needle light?

Thanks.

Speedometer--

The two spade connectors are attached to bulb holders for the 2 gauge illumination lights (dash lights). The bulb holders should with some effort slip from their interference fit receivers, unless they are significantly corroded. The speedometer is the only gauge to have two illumination lights.

Multi-function Gauge--

I've actually seen at least three different plug in connectors for the back side of the multi-function gauge assembly, some with two wires. In your case, when looking at the back side of this block, the following applies:

-The black wire on the multi-function gauge connector you have pictured is a hot wire that connects to the fused side of Fuse #10. This will provide 6V or 12V power for the gas gauge, oil light generator light and the two flashing turn signal indicator bulbs.

-'G' as you mentioned goes to the fuel tank sender connector at the top of the gas tank. This will usually be a brown wire run through a black sheath for added protection.

-'K7' (top-center) is your gauge illumination light wire, which should be gray with a red stripe.

-'K3' (9 o' clock) is your flashing indicator lights. Though it may seem odd, both left and right bulbs flash together any time the turn signal indicator is activated. This wire will typically be blue with a green stripe. Depending on year and flasher relay used, you might have the wire tie to the black with green and white stripes at the '+' side of the 2 prong relay, or directly to its own 'K' connector if a genuine early 3 prong relay is still installed.

-'K5' (4 o' clock position) will be a gray with black stripe wire. This is a shining beacon of just how cool and unique the Type 34 really is. It's the wire that goes to the fog light indicator bulb telling you that your fog lights are on (hopefully).

-'K1' (5 o' clock position) will be your high beam indicator bulb power wire. Blue wire with a white stripe.

-'K2' (7 o'clock position) will be your generator light. This will be a blue wire.

-'K4' (8 o' clock position) will be your oil pressure light. This will be a blue wire with a green stripe.

If at any time you smell something burning, then none of this applies! Remove power and yourself IMMEDIATELY.

Greg, I thank you for your help. A gerat deal learned! I would have probably chased down the 'K3" double-blinker for a year without knowing that was how it is supposed to be.
