Here is the Warning from the AAW 510089 Classic Update Kit.
"This kit
WILL NOT support the use of a factory ammeter. All AAW kits are engineered to supply the optimum charge to the battery. To achieve this performance, we route our 8ga. charge wire directly from the alternator output charge terminal to the starter battery terminal. Due to the path of the charge being altered from the
stock configuration, the gauge can no longer see a charge vs. a discharge, so it will not work properly. When ammeters were originally used, most generator or
alternator current outputs were rated at a maximum of about 25-60 amps. Modified cars being built today typically utilize a 100 amp or higher output alternator.
With these higher current units, ammeters, generally speaking, become a safety hazard. Ammeters are usually wired in parallel to the charging circuit, are
typically unfused, and can short very easily causing a fire. A voltmeter is recommended as a good alternative."
Tom is building me a cluster for my LS swap so I asked him if he could include the volt gauge. I guess I'm the test mule
