64 instrument panel lights

[rdlackey]

tested with test lamp.

1. turned on the light switch and checked for voltage at the instrument lamp fuse. (NONE)

2. Connected a jumper wire between the instrument lamp fuse and a hot fuse terminal. Cluster lights still do not work. But, test light lights at the instrument panel fuse terminal.

When I turn on the light switch, HEADLAMPS and PARKING LIGHTS work. Instrument lamps do not. Dome lamp does not (even though, test lamp lights up on dome lamp fixture terminals).

Beginning to think that I have a partially bad light switch. So that I can further test the green and red wire connections within the switch, how does that switch disconnect?

Sorry, I worded that badly. What I meant was to put the jumper across the terminals on the connector, not the switch. This is to check the wiring from the switch to the fuse panel. The connector unplugs from the switch, and there should be no need to remove the switch from the dash unless you haven't got enough room the get the connector off.

However, it would appear that you have yet another problem (or two, if you count the dome lamp), because when you apply power to the instrument lamp fuse, the lamps should light. You will still need to troubleshoot the cluster, the cluster connector, and the wiring from the fuse panel to the connector. I would recommend that you attack this end first, or else the test at the light switch isn't going to prove anything.

Here is a schematic that might help.
