Console volt meter gauge issue 68 SS/RS
« on: December 18, 2016, 10:04:30 PM »
Mine is not working. Noticed I have later model alternator with internal regulator.  Appears it is supposed to utilize a dash warning light only if it is not charging? Can I get it to work with my console gauge somehow?

The console gauge is an ammeter, not a volt meter  (well, technically I guess it is a voltmeter that is looking at a voltage differential to determine how much the alternator is charging).  Either way, I don't know the answer to your question regarding using the original ammeter with a different alternator/regulator set-up.  Hopefully, someone else can answer your question.  However, there is a voltmeter available that will install in place of the original ammeter and look like it belongs there.  It is made by American Autowire.  I installed one in my car, and it is a very nice upgrade in my opinion.

The Ammeter wont work if the external regulator is not utilized. It senses a voltage drop - or increase + from two different locations as a shunt and this difference is picked up at the meter. One of the locations is at the external Reg.

I don't think that's quite true Steve. I have an internally regulated alternator and my ammeter works just fine. I just used the adapter adapter kit from M&H (their P/N 27555). Everything else is completely stock. (NEW, but stock.)

Posted with permission from the author, here's the wiring diagram for the ammeter from the 1969 CAMARO WIRING DIAGRAM AND ELECTRICAL TROUBLESHOOTING MANUAL by Larry DuBois.

You are correct. If the adapter is used and the ammeter loop is not broken the ammeter will function.

I also have a similar problem after fitting a newer larger alternator.
I routed the alternator positive directly to the battery as it is a 100A alternator and I didnt think the factory wiring would handle that.
I still have the original charge wire connected to the alternator as well but I unplugged the old external regulator.
Hence my Ampmeter doesnt go.
Referring to the drawing above:
My wiring is the same except that I also have a larger charge wire going directly to the battery
Am I correct in that the pin #2 of the old regulator is the reference loop?
So basically my charge system is wired as above, if I connect only the wire for pin #2 my meter should function?
Thanks

HERE'S some info from the International Scout site that might help. (Uses the same alternator as the Camaro) The 3rd reply down shows how to wire it up.
