[DeTomaso] Electrical problem from Japan

I agree with Mike-- basically symptoms of a low battery-- less than 12V at the battery proves it.
The question is, how did the battery get low?

Must be getting inadequate charging  (only 9.7v at idle) either because of the alternator or voltage regulator

On my Dino recently the VR was causing the alternator to charge strongly all the time, which caused the alternator to fail.

I use my ignition cutout / antitheft switch to help hot starting-- don't activate the ignition until the starter has the engine spinning

 The low voltage is one issue, but the click is another. There is a bad
 connection in the starter circuit or his solenoid is giving out. If he has
 the interior light on and tries to start the car, does the interior light 
 go
 out or stay the same when the click is heard?  If it goes out, the starter
 is either zapping all the power the battery can provide or there is a 
 short.
 If it stays the same, the starter is not getting enough juice. I'd bet the
 light stays the same and the starter is not kicking in. In that case, 
 start
 with cleaning all the wires going to the starter and solenoid.
 
The car starts just fine when cold, which would tend to eliminate the 
heory of bad connections (although I did tell him to go through and check/clean 
everything).   In this instance, the car had been idling for an extensive 
mount of time, with the radiator fans etc. draining the battery and the 
lternator failing to properly charge.   Finally the battery just died.   The 
click' is a standard symptom of a dead battery.
When left overnight, the battery recovered enough juice to start the car 
p.   A pretty typical story...
