[DeTomaso] Amp gauge

[Forest Goodhart]

You are both right. The alternator output is connected directly to the load side 
of the ammeter so both answers are the same.

>>>Actually, the *correct* way is to connect the load to the ammeter.  
That way the ammeter reads correctly under all circumstances.  You WANT to run 
all electrical loads through the instrument that is designed to measure all 
electrical loads. :>)

With the various fan/headlight relay kits out there (Moseley/Boschert/ 
Volts of Confidence/home-made), an aux fusebox is powered from the ammeter.  
When the fans kick on, the ammeter shows an initial drop, then the needle 
comes back up as the voltage regulator steps up to allow the alternator to 
produce additional power.
