The 1968 alternator gauge is 'smoked' The replacement Stewart-Warner gauge is different - it reads "Amperes" instead of "Alternator". I would like to save the casing on my unit...There is a detent on the rim of the casing and looks to me like the main cap would "pop-off", like a watch case.
If this is rebuildable could you recommend someone...If not, would you know of anyone selling this model...
Any thoughts...

First & foremost, is there any sign of a manufacturer logo, label etc on the original gauge you have?

Second, what make of vehicle or machine is this gauge installed in?

Fahlin Racing,
Yes, SW. The gauge is installed in the console (next to the oil pressure guage) on a 1968 Ford Mustang 428CJ FB equipped with a 4 speed manual trani.
 
My final piece of advice to you is to quit pursuing the alternator fix UNTIL you get the starter to work. you can by pass the gauge as it is not required to start the engine. chances are a wire is shorted out to the point is is brunt in two..the gauge may be the faulty connection.
in any event you can run new wire from the hot side of the ammeter to the connection if need be...BUT
as far as you have told me..the starter has not spun since the original smoke event.
until you can get the starter to work..you have a classic car stationary monument...

Ranger Mike,
To the Ammeter guage: Run a new wire from the hot wire to what connection?

Have you checked with Stewart Warner for service parts yet?

Is this a two-inch diameter gauge?

I could check in the catalog at work, although it won't list them in a application order in our gauge catalog. Picture of the face possibly so I know what to try to look for?

Yes, I believe so Fahlin Racing. This is the best I can do picture-wise. This is a Stewart-Warner gauge from the year 1968.

Well, right off the bat, there is no gauge in the catalog like that. Like Mike mentioned, Yearone and other sites that were mentioned by others. I will try just to make sure though.

Q:
Is this alternator gauge rebuildable, or not?...There is a detent on the rim of the face and looks to me like the main cap would "pop-off", like a watch case.

The Stewart-Warner (SW) model is from 1968. If not, I would like to restore this one or purchase NOS (identical to this model).

Q2:
Option- to disconnect my faulty alternator gauge and safely wire up this circuit. How do you connect these 3 wires (live, return and ground)??...

i would send the amp gage to the link i gave you in California ..have them give you quote on cost to rebuild...
on wiring ..simply connect the to wires from th e amp meter togeather and MAKE SURE you do not connect a ground wire to these two hot wires..also tape the connection so you do not chance grounding it and causing a fire..
and...make sure the wires are not fried, or have melted any insulation off ..be carefulllllllll
