Given we all tend to bypass the factory Amp gauge due to the lousy design and potential fire risk, I wanted to do a constuctive mod. Converting the Amp gauge to a voltmeter is pretty straightforward though fiddly job. I’m not taking credit for this, a mooch around the net showed it’s been done many times. This Bosch gauge is recommended as a suitable candidate.

First job is gut it, the face comes off with 2 tiny screws. The face of the factory Ammeter is held on by 2 tiny rivets, I cut through them from behind so as not to damage the face.

Tidy!

Very nice.

Next step is to glue the Bosch face under the mopar face so that you can use the tiny screws to fit it all together.

Next comes the tricky job of snipping off the original needle and gluing it to the new needle as it’s a different shape and needs to be moved up a bit to match.

Final step is fitting a Voltmeter decal to complete the look. Can all be reinstalled now and wired to suit. I need to check but I think all that needs doing is to move the large red and black wires for the Ammeter onto one terminal of the voltmeter and earth the other side, assuming that’s the case it doesn’t even need wires cutting.

I think that’s a really tidy way to do it. Looking forward to seeing it installed.

Nice work!

Couldn’t help noticing just how heavy the pot metal instrument housing is, I’ll be having a look at that….

More holes coming?

Indeed, it’s considerably lighter now, probably half the weight it was. I have some self adhesive chrome tape I’ll apply to the inside so it still acts as a reflector for the panel lights.

Modified my shiny new Dash trim to take the gauge panel I made last year in the heater control area. This will place the oil pressure and mechanical temp gauge in an area where I can easily see them. Under the dash might look cool but it’s hopeless if you are actually going to use them while driving which I certainly do.

Ready to go back in, usual repro part niggles but it looks pretty good overall.

That looks fantastic
