Re: Restoring Rusty - Voltmeter Wire Color
 
Guys set me straight here please.

Where does the signal to the voltmeter come from, and what color wire does it travel on?

I know that the oil pressure comes from the oil pressure sending unit via a tan wire, the coolant temp, comes from the coolant temp sensor via a green wire, the fuel level comes from the fuel sending unit via a tan wire. All these wires enter the bulkhead connector and then route directly to the circuit board.

I was able to cherry pick my TEK out of a stack of Surplus scopes and I got lucky.

Once again, "Oh my..." That's why I'll be checking in with you again real soon. It was your insight along with a couple other folks that reassured me that I was buying the correct cluster for my idiot light to gauge conversion.

No thread to prove it but I'm down to the frame and ready to come back up. I'll be installing my gauge cluster and repinning the connector in my 79 real soon.

Keep up the good work and documentation "G".

Been outside working on my truck all day. This was a great find as I go into resting mode for the evening. I'll be going from a 79 with the idiot light pinning to what you have just posted...I think?

Thank...

The voltmeter is just fed from the +12V power that powers up all the other gauges. There is no "signal" wire.

Thanks the 3 prongs confused me, I looked at it again and two of them are ground on Pin #3 so yep you are correct, than you for the explanation

yes I am so anal I pulled the proper three prong pink wire instead of splicing in another wire to my old one, it forced me to learn where it goes (same on the '74 as on the '76 by the way but different on the '79)

the screw driver is wedged where it plugs in to the fuse block

Re: Restoring Rusty - Clutch Switch Delete

thought this was as good of a time as any to delete the clutch safety switch even though I had the loop thing pluged in there for decades, no sense of wiring such a heavy wire two feet up the steering column if you don't have to

super easy delete, just unplug the connection from the white plug where it plugs in to the clutch switch and take that wire and plug it in to the bulkhead connector directly, this will continue the purple wire path to the starter, job done

gauges going in...

in the end here's the verdict

Speedo - works

Water Temp - works

Oil Pressure - works

Tachometer - works but is inaccurate

Voltmeter - does not work

Fuel gauge - is missing

Classic Parts has that fuel gauge -- 50 bucks. You might want to try to scrounge that!

Gregski the calibration is ez. What I did was hook up a tach under the hood and hooked up the raw factory tach right beside it . As said earlier, that little blue part you solder on has small adjustable dial on it. Just turn it until your factory tach matches the good tach, run a few different rpms and all good. Yeah that dude is an electro tech. But I did it just like I said and is quite easy once you filter out the nerdspeak .

well enuff of this electronic stuff, let's see what else the Greg has been working on... how about them Visors

first we had to remove the old swivel stick or bracket out of the old ones

not sure if I should be mad at LMC Truck for being such cheap donkeys and not including the swivel sticks when they sell you new visors or thanking them for keeping things so modular

when we wiped the sticks off a bit we noticed they are labeled R (Right) and L for [wait for it] ... (Left)

and that's why we clean our parts

oh wait I see, cool thanks, I did not know that's what lurked inside them little rascals ...

of course nothing's easy but everything must be black, so we used some Denatured Alcohol to wipe off the ol' swivel sticks and tapped them off so that they could be painted black, just using the same semi flat black we used under the hood on the engine bits

to slide them in was a pain, I did not know weather to lube them up with the Rich recommended white lithium grease or slip them in dry, so I split the difference and lubed one up and left the other side dry, LOL

in the pics the sticks are still not slid in all the way, (as I came to find out when I went to mount them)

Hey! You found the visors I have in my 64. That's something I need to fix one of these days...

Well after threatening to buy a new used voltmeter on eBay, today mine started to work!

LOL, The Greg was hurtin' for dough at the end of the month so he had to lay low for a week or so, I mounted the huge clutch pedal spring but there was not much for a picture opportunity

but as of the first of the month he has already ordered the following

1. Brand new fuel gauge

2. Another used Tach off of eBay (for $45 bucks I had to take the risk)

3. Brand new Holley carb tunning kit [more on this later] but it does involve a Test so you all may wanna study up, hee hee
