Ammeter to voltmeter conversion
I'm sure this has been discussed here before, but nothing shows up in a search. I would like to convert (or should I say replace) my ammeter in my rallye dash with a voltmeter. I have seen it done on other Mopars, but none of those were A bodies. I can remember an article somewhere that explains it in detail, including the make and model number of the voltmeter needed. I can't locate that article, either. Can anyone here help?
Thanks!
This is a very worthwhile conversion.
I used a SunPro CP8215 Voltmeter . Readily available on Amazon. I took the face plate off the factory guage and installed it on the Sunpro unit. Fit with very little mods. Wiring posts lined up perfectly.
Some things you need to to do:
1. Connect the two leads of the ammeter together. I cut the ends off , spliced and soldered them together then used a heavy heatshrink to insulate them. You cannot attach the ammeter leads to the new gauge.
2. Get some testors Orange model paint and paint the pointer as it is red in the sunpro unit.
3. Insulate the wiring posts from the sunpro gauge as they can short out against the metal housing of the gauge cluster.(Ask me how I know . LOL !! )
4. Connect the negative terminal on the gauge to the cluster housing , connect the positive end to a switched 12 volt source at the fuse box. I found an unused terminal for the radio.
The pointer will be pretty close to half way when the voltage is at 13 volts according to my Digital Fluke Meter.
My conversion is working perfectly after 3 1/2 years.
Hopefully I didn't forget anything but I'm sure other members who did this will chime in.
