Got this beauty from the famous auction site, it came half way round the globe from Australia



It's in great shape and still has its original stiff paper insulator on the back

The insulator is fixed to the bracket, has markings for the two posts; "AM" and what looks like "I" stamped on it, it also has brass rings which sit around the posts.
The gauge itself has been sealed with some type of waterproofer around the cork insulators on the posts, each post has three brass nuts and a lockwasher

The jeep had a repro amperes gauge (ammeter) fitted

Under the dash this is what the repro gauge looked like, the gauge at the bottom is the temp. In the second pic the lock nuts are off showing the wires attached, three to one post and one to the other (I'd love to tell you what they are .... but I'd be guessing )


To get the repro out and NOS in was like having a game of twister without the mat! I shouldn't have to do those kind of contorsions at my age. I ended up lying on my back on the passenger seat with my legs hooked over the back of it and my head stuffed under the dash and twisted sideways.
Tip: if doing this, fold down the windshield as it prevents you clouting your head on the gunrack 
Comparing the two gauges was interesting; Repro is left, NOS is right



The most obvious difference is the shorter needle on the NOS, it also has "amperes" scripted differently and the face fixings are in different places.
I was struck by the relative closeness of the shades of OD between the repro (Dallas Autos Flat OD) and the NOS. The NOS was almost the same green but with a hint more black - not bad for 1 year old paint vs 60+ years old!
Having compared them I then stuck my head back under the dash and fitted the NOS gauge in place (having isolated the battery first!!!). I hoped that the posts on the NOS were the same as the repro and just wired it back in as it was. The repro gauge was unmarked so I had no clue if it was right. It worked first time but with discharge and charge the wrong way round! Never mind, just reversed wires on the posts and hey presto 

I also managed to fix and re-install my NOS oil pressure gauge, the threads were still good after all! So, when the Motometer speedo is in I'll have original gauges everywhere except the water temp
