<VV> Dim lights at idle

[FrankCB at aol.com]

James, 17.5 volts will burn out your light bulbs and WAY overcharge your  
battery!  Get a new voltage regulator before that happens.

The  dash ground seems to be ok.   I put a meter on the car and it was  
12.7 volts before running and then running with the alternator loaded up the  
voltage is high - reading 17.5 volts. Yikes!     Cables ohm out  ok.  Voltage 
regulator maybe stuck?Jim

Hello All,  We  took our '65 Monza sedan out for a bit of driving after 
dark tonight and I  noticed something I had not before.  When at a stop light 
at idle and  especially with the PG transmission in drive, the dash lights 
get really  dim.  I don't really notice the headlights getting dim but the 
dash  lights sure do, almost to dark.  And then when driving away and the  
engine revving up the dash lights come back to normal, but not  instantly.  I 
will  put a voltmeter on the car tomorrow and check it  out but I wanted to 
see if this was a common thing with LM Corvairs.  I  remember getting low 
output from the earlies with a generator.   I  would expect some voltage drop at 
idle but I'm not sure why it is so bad at  the dash lights-  because of the 
dimmer circuit?The battery in the car is  a new one and the wiring I 
checked was good.  Maybe I have a weak  alternator and its time for a fresh one 
and new regulator.  I don't know  the age of what is in the car  now.Jim
