instrument lights-HELP!

[pestwagon]

in my 1964 Chevy pickup ....

When I bought it the oil pressure gauge, ammeter, fuel gauge and water temp gauge all were not working. The speedometer was broken too. But the turn signals and instrument cluster lights worked, as did the dome light switch and headlights and brake lights.

I got another gauge cluster, refinished it, and installed it. Now all the guages work. Fuel, oil, ammeter, and water temp. Lubed and reset the speedometer to 00000.0 and it works perfect. Brake, turn signals all work.

But the instrument cluster lights dont work at night. All the bulbs are new. I have power (12V) at the fuse box "instrument" fuse on both ends when the light switch is pulled out. I ground the back of the dash to the steering column with an additional jumper cable but it doesnt work still. Any ideas?

Move this to electrical if need be modulator....

Check your headlight switch. Ex

After ensuring bulbs are good, run a loooong ground from dash cluster to battery neg--booster cable works really well. If they now operate, just find a closer, good ground.

Found the problem....(really stupid one) Had a loose connection at the connector from the dash harness to the gauge harness. The grey wire there is the instrument lights and the spade was making an improper contact. Once straightened out it was fine... Thanks guys!

Yep, sounds right. Grey is the instrument cluster lights. Ground, ground, ground....real big with these trucks.
