ammeter guage F

[Lindsey Fiuller <lfuller@xxxx>]

getting ready to do a road trip & my ammeter on my F is either acting up 
or the system isn't charging right. Just starts registering discharge 
while driving. Tapping the voltage regulator makes no difference. I have 
had this problem intermittently since replacing the voltage regulator & 
rebuilding the Generator last year. Any ideas? Anyone see any problems 
with installing an after market under dash ammeter just to be sure? Thanks.
