help with 61 gauges(chrysler)

amp gauge works.fuel,oil,gas dont.i have 12 volts to the lead gauge,and a pulsating 6 to the other 2,which i believe to be correct.ground is good to the cluster as my turn signals work.are all 3 bad?? senders are also new.i can ground the gas tank sender and gauge does nothing.im just having a hard time believing all 3 are bad.what are your thoughts?im off to work will check back later

"fuel,oil,gas dont"

Fuel should go to full if you ground the wire back at the sending unit. Do not leave it connected straight to ground for long. 5-10 seconds should do it.

Oil is the same. Disconnect the sending unit wire, turn the ignition on and ground the wire. The gauge should go to max. This can be connected longer.

Is the third temp? If so, do the same test. It's best to have a helper in the car to turn on the key and watch the gauge while you connect the wires to ground.

As with any electrical issue, start with a fully charged battery and good connections.

sorry,was kinda asleep this morning.oil,gas,water temp.all dead.gauges do nothing when grounding the sending units.and i did not leave them connected,just long enough to see.

Don't 61 Chryslers have electrolumenescent gauges (lighting strips, no bulbs)?

I've never messed with a 61 Chrysler, but my 67 Charger has the electrolumnescent setup. The lighting is high voltage ac, wired in series. Besides the lighting strips, the gauge pointers are "hot" as they light up too. If one gauge goes out, or there is any kind of short anywhere along the way, the oil pressure, temp and gas gauges all quit working.

If this doesn't apply to 61 Chryslers, just ignore this post.

yes,but its my understanding but that actually has nothing to do with the operation of the gauge just the lighting of the gauge

I tend to agree that it's pretty unlikely all three gauges went TU but, to eliminate the IVR as the problem, I would hook up a 6V dry cell lantern battery as a power source just to be sure.

ill sure try that.

gauges were all stuck,pulled them out and sprayed contact cleaner on them and very carfully worked them until they were free.very happy they all work now.horray

The gauges as said are standard.They have a coating so they glow with the lights for the dash.We bought 2 NOS power packs for the lights.Rocky
