[T3] Charging issue still

[Bob Rogers]

Tim, when working on my '73 I noticed that someone had mounted the generator improperly.  When mounted correctly there is a hole in the bottom of the generator that allows it to receive cooling air.  There is a mark on the top of the generator that must be lined up with the notch in the clamping strap.

  I have finished re-assembling/wiring my '73 T-3  F I Automatic.
  It sat for 30 +/- days and fired right up. The volt meter wired  
  directly to the battery went 12.4 v to 12.1 v when I turned the key on  
  and the pump ran, then went to 12.4 v again. Engine turned over  
  quickly and fired within a few revolutions. While idling cold and R P  
  M's elevated the voltage went up to 13.9-14.0 v. As i loaded the  
  system with lights fog lamps etc the voltage dropped to 13.0 13.2 v  
  under full load. I drove the car for about 3 to 4 miles and as the  
  engine temp. approached normal the voltage on the battery dropped.   
  When I completed the 3 to 4 mile loop the battery charge would barely  
  read 12.4 at 40 mph and no load. The battery is 3 years old and seems  
  to hold a charge. ( We left it for three months connected ( clock only  
  drawing power ) it turned over and fired off as if it had been sitting  
  for a few days.) I'm thinking the generator has an issue that is temp.  
  sensitive. Any thoughts/ideas or has anyone experienced anything  
  similar.
  Thanks in advance
  Tim
