Cluster Bench Test
I am in the process of testing the cluster before it is reinstalled. I have it powered. All lights except the following are illuminated.
Turn signal lights left/right
Hi Beam
Parking Brake
Lights
According to the paper all lights should be on: Picture below.
Also what is this brown wire for? Have the others sorted out.
Need advice.

Brown wire is to the radio capacitor-----should be mounted on back of cluster
Left and right turn-----on the connector to the turn signal switch, two connectors will have two wires. One pair LBL (light blue) and the other DBL (dark blue). Touch 12 volts to those.
Hi Beam-----on the dimmer switch connector, look for a LG (light green) wire. Touch 12 volts to it.
Parking Brake----look for the connector going to the parking brake switch. Touch a ground to that.
Lights. On one of the bulkhead connectors there will be a GY/DBL/B (grey, dark blue, black?) wire going to one of those terminals. Touch a ground to that. If you can't find it use a straight pin to give a ground to that wire at the Lights socket.
When using the "Touch" wire always put a couple amp fuse in series with it----in case you touch the wrong wire.
BTW these colors are for a '66----

Hi Beam-----on the dimmer switch connector, look for a LG (light green) wire. Touch 12 volts to it. Ok, This worked
Parking Brake----look for the connector going to the parking brake switch. Touch a ground to that. Only works if I turn the ignition all the way to the right "start position"

Is this the correct orientation for the bucket switch?

I have a ground from the battery to the cluster that a jumper from the ground to the pin and no light. Checked the light out of the socket and it is good.
According to the test paper if you hook the power to the BAT terminal all lights are to be on, nit my case. If I hook the hot to the ACC dash lights come on.

New wiring harness from M&H, cluster rebuilt from Corvette Specialties of Maryland.

Probably something got left out (like: "except for brake light, etc") or the wrong picture was used.
Makes me think so even more because they give specific instructions on how to make the signal lights turn on (pg 13), dimmer light turn on (pg 15), brake light (pg19) and lights indicator (pg 8).

Tried with the lights on and off. Tried with the ignition switch off and in the run position.
Could only get the brake light to come on when I turned the ignition to the start (far right) when I released it to the run position the light went off.
This is why I wonder if I have a problem with the ignition switch.

Are you saying that the picture could be wrong that all the lights will not illuminate with the basic test of Grd and positive to the BAT in the fuse panel?

Correct. Take for example the turn signal lights. The bulb is grounded at the cluster. The other end of the bulb's filament is connected to a wire that goes to the turn signal switch connector. If no switch is installed it all ends there. No way for the bulb to come on, i.e. get power to light. Now if the TS switch and flasher were installed, pushed to either turn position and ignition switch turned on the bulb would flash. But only one bulb, not both-----and not both constantly.

Found the problem. Removed the BA9S-CWHPS LED and replaced with Chineese 257 bulb and whamo it works. Now dealing with the Brake light.

Working on a clarification of that page with help from Tim Welsh and Rich Mozzetta.
Will post up the clarification when I hear back from them regarding the edits I have made to page three.

Richard Mozzetta helped me resolve my wiring issue earlier this night.
Thanks to all.

My problem now is, when I check headlight (telltale) bulb (pg 8) the "LIGHTS" indicator on the console blinks on and off....at a slow pace. Not sure if this is correct or my switch is bad.
Thanks,

When following the write-up I came to this exact conclusion. It had me worried at first, before I thought about the turn signal switch not being wired in.
