Fuel/Temperature gauges

Hi,

I noticed it has been a couple of days since we heard from you. Has any progress been made? We are interested in knowing.

Take care and let us know if we can help.

We are assuming things are hooked where they should be.

Lets unclip the wire on number 6, it should be a pink wire. Is it pink?

(it is the sender, all the way from the tank)

Gear shift in neutral wheels chocked

Turn on the key to "on"

Did the fuel gauge do anything?

With an alligator clip jumper, clip onto the female of the wire you just removed. Ground the other end of jumper to a good ground

The fuel gauge should rise to the top. Does it?

Fix everything back

While we are at it do the same for number 10, the temp gauge sender

This wire should be purple. Is it?

Let's ground that wire too, the gauge should rise to, and maybe past the top.

Okay, put everything back and post your results.

Depending on your results, I may be able to focus on a direction to continue on with.

I'm not exhausted yet!

2nd diagram upper right side displays the wiring to the speedometer gauges. The rest of this diagram is for a 1979 some may not apply to your year. The dashes I place on wires denotes that it has a tracer stripe the stripe colors were not denoted in the legend

Here's my Blob---goes behind the Dash.

Not sure how you hooked yours up,

Any kind of oops! Might be fatal to the gauges!

If you are unsure of something, before you just "Go for it", Maybe I

can explain better or a different way.

I just read back through

Temp gauge runs backwards?

See how I introduce 5V to the fuel gauge---jumps to the voltmeter with the original jumper.

The Fuel gauge sender wire is pink

The temp gauge is Purple.

Over the years, the gauges may have been changed to aftermarket stuff

Here's 2 of mine, like the originals, the "zero" for both gauges is all the way to the left---the ones in the boxes too (one is upside down)

Some aftermarket stuff the "zero" is the the right---they travel backwards from the way the originals do (cold and Empty are on the right)(Hot and Full are on the left).

I have not ever installed those types----Without their instruction sheet to go by, they might have the posts reversed in their back side.

Experimenting by playing "Musical Wires" with any of your gauges (even for a split second) most likely will leave you with a sad face!
