[DeTomaso] DeTomaso Digest, Vol 98, Issue 14-alt running

[Tomas Gunnarsson]

For those who understand: remember that even if the alternator regulates
the output internally the output would likely have a very big ripple
voltage as there's no smoothing after the rectifier diodes. The output
may have a peak voltage well in excess of 14 V even though the
regulation is in operation.

Davis,

I think that is true as long as the one-wire alternator is operated as a
pure one wire. If it is operated as a three wire, the situation may be 
different. The one-wire alternators may have voltage limiting as part of
the 
integrated regulator...... I don't know and not seen anything on that
subject.

Have fun today,

Bill,

is it fair to say that this is not the case with a 1 wire alternator
which 
will limit its ouput to ~14- 15 volts over the resistance of the 
consumers. i.e. adjust current output to never exceed the 14 - 15 volts?

A word of caution:

Never run the engine with the battery disconnected.

The OEM Pantera alternator will raise it's output voltage in an attempt 
to 
charge the battery and thus raise the battery voltage. Since the battery
is disconnected, the battery voltage will be sensed as 0 volts and the 
alternator will raise it's output voltage some more.

All the active power consumers on the car will be fed by the
continuously 

rising alternator voltage.

You get the picture.

Have fun today,
