69 Dart dash volt regulator

[mycuda]

Hi, Can you test dash voltage limiter/regulator by itself on the bench?

Had gas/temp gauge working last I checked. Not now.
Dash lights, brights switch, front /rear lights, brakes etc. work.
However steering column out at the moment, dont think its a ground issue.


Thanks.

Just the IVR? doubt it. You would have to simulate the load of the gauges.

Here is some of what goes wrong..

Obviously the IVR itself

If only one gauge works or seems inaccurate, the gauge unit

gauge sender

wiring between

ANY connections, including the wire end to the sender

At the dash, poor connections at the cluster connector and broken / loose pins on the circuit board

Also, bad connections between the IVR contact fingers and the printed circuit

And loose / corroded nuts on the dash instruments.

You can see, that after 40 plus years, "it adds up."

Thanks.....
Just hate removing gauge unit and scratching the **** out of everything on something I thought I already fixed. I must be getting old(er)
WTF

Try connecting 12v and a ground to it. Then touch a test light to the output post. The light should flash off and on slowly. At least then you'll know the contacts are working.
