Well with the threads I have seen here and elsewhere I decided to open up my gauges and see just what condition they were in on the inside. All and all they are in pretty good shape. The reflectors are bright blue like they should be and there was no rust to be seen inside the cases. I decided to just clean them up a little and re-assemble them. I need to get a few more 194 bulbs, but all in all it was an easy project.

Those are VERY nice looking originals! What was the red 'jewel' from? Hi beam indicator??
If they were too dim to start with, 168 bulbs in the gage illumination sockets will brighten them up a bit. I use 168's in the warning lights and turn arrows to make them easier to see during the day.

 

Randy thats a nice little rainy day project.....er winter for some of us

Thanks for showing us the details.

Snows clock shoppe.....looks somebody has been in there before. Does the clock still work? Thanks again.

 

No the clock is busted...again it seems.

I am now having an issue with my temp gauge. It's pegging when I start the car. I have no clue why as I re-assembled it the way I disassembled it. I took my VOM to it and there is continuity EVERYWHERE. I can touch either post on any gauge and get continuity between any other post. It's the damnedest thing I have ever seen. It's really odd because the gas and oil gauges work the way they should, just not the temp.

And yes the red is the high beam indicator. That was something I didn't expect. It just fell out when I got the face out of the housing.

 

Told ya it was easy. https://classicoldsmobile.com/forums...storation.html
Rob is the one who started me on it with his clean up.
I would suggest repainting the interior of the gauges gloss white.
I also painted my trim ring reflector gloss white as well because I'm using LED's.

You'll get much better reflection of the light.
Mine looked like total ***.

I said F' the stupid clock conversion because I heard they break repeatedly.
So I forked out for the aftermarket Tach for $200.
Fedex is so far behind it was supposed to be delivered 2 days ago.

 

My high beam indicator is blue.

 

Obviously something happened during the reassy.
Time to pull the gauge again and look for a short. Make sure none of the pins on the PCB did not come loose and push back into the metal case when the connector was pushed on.


Mine too. Earlier years were red, then changing to blue later on.
I remember a whole thread being devoted to the red vs blue hi beam light last year!

 

Where can I get a blue tube for the high beam indicator ?? (and what years???)

I hate the red thing.

Alls it is, is a mini paper roll with a plastic translucent cap on it.

 

Ace 1970 was the last year for the red indicator. If you can get your hands on a 71/72 speedo you'll have a blue one.

 

Ace, just make your own tube.
Take a toilet paper roller, cut it down, use lots o' glue, and you're done!
A blue plastic scrap will work for a lens.

 

I'm trying to disassemble my tic toc tach... can't get the clock adjustment **** off.Does it just unscrew? I've used pliers and no go.
Thanks for any input.

 

Wish i knew the answer - I just left mine on during the painting and resto process.

 

Never mind...I just found it in the service manual. It says to hold the shaft with needle nose and unscrew it. I guess mine is just seized.
Thanks anyway

 

Well apparently I didn't assemble it the way I disassembled it. I saw 2 different pics of the back of other peoples gauge sets and it seems I reinstalled the damn resistor on the wrong pins for the temp gauge. I swapped it back to the correct position on lunch today and, voila, all is right with the world again

 

Did you forget the "in reverse order" part that they usually say in the FSM?

Glad you found the issue and got it right and working!

 

Anyone know where you can buy replacement resistors used on the back of the these gauges?. What are the ratings?. I believe the colors define the rating...…The originals are just wound wire on a ceramic or fiber board. Mine maybe fine, but just want to chelk them to see if if oil gauge has a bad or going bad one that maybe causing the fluttering/step issue I am having..thanks
