Next I removed the Amp meter from the Instrument cluster. By the way the voltage regulator you see there is an electronic one, I followed the instructions in the archive, gages are rock solid. Back of cluster. Heres the amp gage out of the Instrument cluster. Amp Gage

Next I removed the face plate from the voltmeter and did a test fit in the instrument cluster. Notice the resister and Poteniometer at the bottom, that was hitting the instrument case. That would be a no no. So I double nutted the post the resistor was conneted to and very slowly turned it CCW looking at it to spread the resistor from the pot. Then I carefully bent the pot over toward the rear to give me about 1/8" clearence. Voltmeter in Instrument cluster. Now I found something really interesting the faceplate bolt holes were almost identical so I could use either the old face plate, which would look stock, or the new faceplate from Sunpro. I decided I wanted the new faceplate but you could go either way. To use the Sunpro faceplate you have to cut off some of it. Modified Voltmeter faceplate

The voltmeter come with some inulation grommets to keep it from shortin out, I had to use a rattail file to open up the stud mounting holes, this allowed me to mount the voltmeter sure that it would not short out against the cluster. Back of voltmeter mounted The negative wire I grounded to the back of the instrument cluster. I mad up a short wire with a plug in terminal and ran it from the positive post to a wiring block that was hot when the key was in either run or accesories. Then I performed the mod to directly connect the positive leads that used to go to the ampmeter. I tested the voltmeter before putting it back in the dash with a known power source and a Flug voltmeter. The gage can be adjusted for accuracy by adjusting the pot on the gage, mine proved to be dead on as it was mounted. Completed gage. Well there you go, now I have a working voltmeter in my intrument cluster and have gotten rid of a potential problem with the old Amp gage. Anybody need an Amp gage for a 'Cuda? I have now rebuilt the Tach, Clock, Voltmeter, voltage regulator, and replace the temp gage with a perfect match out of a 86 dodge van.

For a long time I've wanted to remove the Amp meter from the circuit on my 'Cuda but the thought of hanging a voltmeter under the dash and having a dead gage in my instrument cluster did not appeal to me. Following is my mods to the instrument cluster to remove the amp meter from the line and replace it with a fully functional Voltmeter. Located in the archives are the instructions for taking the amp meter out of the line and making a good connection so I will not rehash those instructions. First I needed a voltmeter that had the needle on top like the amp meter and read the voltage under neath. Summit has a Sunpro Mter ACP7985 that did this.
Check out Mopar Action, December 2008 issue (Vol 17, Number 5), they did the Ammeter to Voltmeter Conversion.
Just my $0.00..

Nice work. I bypassed my amp gauge also and added an aftermarket voltmeter. Ron
