I’ve checked and it is charging like it should just no guage.
Is there a way to hook it up so it will read like it should.

The - side of the ammeter connected to everything else.
How to go about integrating the original ammeter into your replacement harness would require intimate knowledge of your new harness.
'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/12
'52 GMC 152 Stake Bed, Original 228, SM420, added A/C, HEI, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.

What you need to do is identify the battey feed for your new harness and put the ammeter in series with it so all of the electricty flowing in and out of the battery goes through it.
If that explanation is not sufficient for you, I would recommend getting some hands-on help because you can make a real mess and cause significant issues if you don't hook it up properly.
That assumes that you have not upgraded to a high output alternator or high-current accessories. If you have, the ammeter might not be able to safely operate. I have never seen a solid, documentes number for the max current on those ammeters. If anyone has one, I would be quite interested in its source. | | |
