So I'm going thru my harness fixing some of the bubba'ed wires...

Always wondered why my trany never shifted correctly!
Anyone know where to get another one of these connectors?

Not sure what this is but it has a spring in it.

Seatbelt sensor bypassed....

Now on to the fun stuff. Center gauges.

This is a 77 and the gauges did work last time I drove it 3+years ago..

Did I mess up by painting this.. causing bad grounds?

Any good way of testing the gauges before reinstall?
I have a vairable dc power supply.

Also picked up a new circuit board.. kinda kewl how it looks compared to the original. I wonder if it will last 30 years

Thanks in advance for any advice or comments.

4th picture is not seat belt bypass-someone bypassed the neutral safety switch.Is your car an auto or 4 speed? 3rd pic is a bulb socket.6th pic of the back of the cluster-I'm reasonably sure the printed circuit makes all connections but the grounds on the gauges could be effected.I wouldnt worry much an about the bulbs but if the metal frame is adding to the ground for the gauges you could stress the printed circuit and burn it.

edit-Looking at it again I believe I would go back and remove the paint from under the grounding studs on the gauges and under the clock hold down screws.

Thanks DWncchs

Neutral Safety.. No need for that

Yes, it is an AUTO for now. The TH400 is the only thing left to fix/replace in the drive trans.

Don't be to sure. I had a friend who was working on his carbs. He went in to start the car and the carbs were wide open and it was in gear. Car went through the back of the garage taking him with it with one foot dragging and went out into the woods. The only thing that killed theengine was a jar of bolts got knocked off and ingested into the carb and wiped out the engine also. Almost tore his foot off spent a few month recovering.

Moral: If you leave it disconnected be careful and warn others.

Did you paint over the gauge mylar circuit? Can't tell by the pic if that is just the back of the gauge console that you then installed a new mylar circuit "board".

I've got a whole '74 harness in a box I could look through, but I've got to have some better pics of the first two connectors you showed...

Did you put A turbo 400 in your 77? My 77 and I thought all 77's had the turbo 350. Do you mean none of your gages work at all? On my 77 there is a black wire into the single connector that grounds the whole printed circuit board to operate the gages you may want to check the black wire.

Ok...

I'm going to fix the Neutral Safety switch!

The Circuit Board is off.. I just panted the housing and was not sure if that was the ground for the meters.. kinda strange that all the connectors for the gagues go thru the metal housing and down't short out.

I'm not sure If they all work or not anymore.. I am going to put the new Cicuit board on and find out tomorrow.

Anyone know of a way to test the meters with a varibale voltage regulator?

What voltage should read what?

BSiegPaint

I will have better pictures soon. You wouldn't want to get rid of that extra harness you have laying around whould ya?

I think it's a TH400.. It is stock/orginal.. It has a th300 torq converter with a 1500 stall and a 400 mounting plate. It was a custom made thing from a company acra torx.. It leaks like crazy


Thanks,
Joel

Papa on the 3 stud gauges the stud with just a nut grounds the gauge and the other 2 studs have a larger hole where the stud comes through the metal housing with a plastic insulator built on the stud.The grounding stud on fuel gauge and the volt gauge ground the clock.

On your temp gauge (the 4 stud gauge)I cant see from the pic but do the 12 oclock and 6 oclock studs have a fiber washer under the nuts? That gauge should have all 4 studs insulated from ground.

I cant tell you how to test the VVR but if you have some jumper leads,12v source and a turn signal flasher I can tell you how to test each gauge individually.

Joel - I can be talked out of it... I have it as a back-up for any issues I might have as I add a '74 a/c to my '71. So far I haven't needed anything from it, but there are some cut wires - it looks like nothing was pulled through the firewall, so I would have everything inside the passenger compartment, nothing for the engine. I can take a few pics and send them to you. It's from an auto car with a/c if that helps. Drop me a PM with your e-mail and I'll send a pic or two or three, then you tell me what it's worth. I might have to pull one or two wires yet, but I'll try and make that determination within a day or so. Bob
