New from n.c. , with a question. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

t&tkennels · 07-05-2008, 08:51 PM

Hi, just joined & already have question. Im in the process of building a mild street rod with a '71 c10 long bed.Im currently working on the inside, & just got done with the paint & dash. Before removing the gauge cluster the lights on the gas gauge didnt work but the speedo side did , while restoring the gauge cluster i replaced all the bulbs & hooked up everything i assume correct & now i only have signal light indicator lights & thats it. Could it be the circuit board gone bad. Im on a very tight budget & trying to do all my own work.Thanks!

kyull67 · 07-05-2008, 09:25 PM

Welcome! It could be the cicuit board as those can and do go bad. I just recently changed my gauges to white with blue leds and noticed that the bulb sockets only work one way. Try taking them out and rotating them 180 degrees. If that doesn't work check the bulbs themselves(size 194's) and there is also a fuse labeled cluster feed. Try those first and if none of those things work let us no and we'll try to help you out.

t&tkennels · 07-06-2008, 05:26 PM

Hi , just checked everything i could think of . Just wondering could it be the headlight switch, although the head lights work fine?. Thanks , i can use all the help i can get!

welcome from winston salem,nc

**clay68c10** · 07-06-2008, 08:27 PM

It could be the circuit or it could be the headlight switch. If it's the printed circuit, you'll still have light in your heater control. If you don't have light in the heater control or the cluster, then it could be the light switch.

**Boog** · 07-06-2008, 09:43 PM

How about the ground wire?

RaceAGMC · 07-07-2008, 05:07 PM

Welome from Charlotte, i'm not much on electrical, hope someone can get u goin.

t&tkennels · 07-07-2008, 09:32 PM

:Replaced the light switch , still nothing. i also noticed my heater control light & interier light are not working, but they use to. Ibought a test light & checked the fuse panel , & the dash cluster fuse outlet is getting no power. How could this happen when all i did was remove the the gauge cluster.?

ok got power to my fuse box, interior light working , heater control light working, & power to the circuit board for the gauges ,still no gauge lights, ive rotated the bulbs , still nothing . Maybe the bulbs i have are not correct but they look the same . Please help!

Longhorn Man · 07-14-2008, 10:32 PM

If the bulbs plugged into the sockets, they are the right ones, or close enough.
Rotating them doesn't matter unless they are LEDs, bulbs work in either direction.
You say you are getting power to the inst panel, did you test the circuit board?
Quick troubleshooting question, does the fuel guage go stupid when you try turning the lights on?

t&tkennels · 07-15-2008, 12:00 AM

hi , no the fuel gauge isnt acting funny. I turn on the lights and checked the circuit board by removing one light at a time & checked each one with a test light & had power on them all.How can they light the test light & not the bulbs ? Im thinking of getting a new circuit board , but hate to waste the money & have the same problem. I just cant think of anything else to check. I will grateful for any help !! Its driving me nuts! All i have left is this & the seat & the inside will be done!!!Thanks for any & all help.

dan42 · 07-15-2008, 12:11 AM

I have the same problem and have had for a while, because I have been too lazy to troubleshoot it, but I replaced: the bulbs, the circuit board, and the light switch. Mine is a '67, but they are the same for the most part. I have also put grounds in the traditional places with no luck so far, but I plan to ground the instrument panel to something that I know is grounded. After paint, quite often you can lose a ground. If that doesn't work, I'll get someone a little smarter than me to at least diagnose it.

Luvlegs · 07-15-2008, 10:01 AM

If there is power on both parts of the printed circuit (lights your test light) - check the bulb holder base - the spots where they contact the printed circuit could have 30+ years of oxidation and need cleaning - simple fix too!

this is what fixed my problem. I had poor ground contact in the socket and had to cean them with contact cleaner and a stiff toothbrush

Longhorn Man · 07-15-2008, 04:00 PM

seems odd to have lost contacts on 4 points across the board, but not the directionals. It IS possible, and a pencil eraser will clean the points.
Have you inspected the ground side of the curcuit? The panel bolts to the back of the insterment panel and provides the lights with a ground.
The fact that the fuel guage doesn't get stupid says the panel its self is grounded.

Ive got the dummy light dash , signals light up fine , & the 2 dummy lights come on when i turn on the switch. just cleaned the sockets & still nothing!

**steelhorse** · 07-15-2008, 08:55 PM

Have you tried hitting it with a really big hammer

and duct tape. You can fix ANYTHING with a hammer and duct tape

babyJay · 07-16-2008, 11:20 AM

The metal contacts inside the bulb base can become separated (stretched) and fail to contact the bulb leads correctly. Try using a small flat screwdriver and bending the parts that "squeeze" the bulb, when inserted, closer together.

ok ,just tried that ,still nothing. i have access to a gauge panel out of a 70' it has gauges not the dummy lights i currently have . Is this a pretty easy swap?.
