69 Gauges?!

[soundkat]

I got my 69 RT down to the MVD yesterday and on the way back I lost the Temp, Fuel and Oil pressure guages? Any easy ideas to fix this? Peace

ground to the dash, or the instrument cluster voltage limiter may be bad...?

Checked ground to column and is good. Where's Nacho, he seems to know about all this pretty good:)

[soundkat]

it was the voltage limiter, what a PIA to get at!!!

Next step is to check voltage limiter as posted earlier.That unit can be a problem.It's old school technology that pulses 12 volts to trick the gauges into thinking their getting 5 volts.

sorry, didn't noticed this topic earlier

I was to say check first at fuse box because must be a fuse what feeds the voltage limiter at cluster, but that is on 3rd gens not on earliers... so next step is simply the voltage limiter

You may want to consider replacing your electromechanical voltage limiter with one of the new electronic ones being advertised in the mopar magazines.  They are kind of pricy at $50 but I think they are worth it.  Particularly considering that one of the failure modes of the original voltage limiter wipes the gauges out.  I bought one but it's packed in a box and I don't recall where right now.  Someone on here will have the link.  This new piece is not a packaged three terminal voltage regulator.  It's a all new design.

If not the fuse, check and make sure the plug didn't fall off the board. Its the plug that goes on the 5 metal pins coming out between the speedo and the gas gauge.
