[DeTomaso] Fluttering Amp Gage

[SOBill at aol.com]

A fluttering Pantera ammeter is quite common.
 
The Veglia ammeter has no damping for the needle movement. The Ford voltage 
 regulator charges the battery with pulses of current. The pulses of 
charging  current cause the undamped ammeter needle to get quite vigorous.
 
See http://www.panteraplace.com/page178.htm for  a description of the guts 
of the ammeter.
 
I know of no real solution to this problem with a stock ammeter and  
regulator. As the ammeter ages the pivot for the needle becomes worn and the  
needle will sure jump about.
 
The main  thing is to keep the main thing the main thing.
Do the best you can with what  your have where you are.
Have fun today!

Trying  to debug a hot start issue, and on the last start, my amp gage
started  fluttering.  Never seen that one before and am wondering if I have
an  alternator that's going bad.  Other possibilities?

Thanks
