Craig replies:
I believe your recollections are inaccurate, John.   One can completely 
disconnect all the wires at the HLRPT on a running Corvair and most 
everything will continue to function. What would stop would be: Battery 
charging, System voltage stabilization (battery influence), and voltage 
regulator system voltage sensing.  The car will continue down the road, 
headlights and radio blazing, with the complete absence of the HRLPT.  
Don't believe me?  Please refer to page 12-27 of the '65 service manual 
and follow the "10R" path out of the alternator.  On the other hand, I 
have repaired a dozen mulit-cavity connectors where the 10R wire passes 
through.  There are Tech Guide articles on the topic too.
