The  alternator is hooked up per the Tech guide, jumper two pairs of wires at 
the  stock voltage regulator and then wire in a "standard" GM alternator plug 
at  the alternator. The voltmeter is wired directly to the fuse block, I 
think the  plug off of the radio fuse. The gauge is a new VDO and the "truth 
source" is  an old (about 20 year old) cheapie Radio Shack analog  VOM.



Hi Nes,
Yes a check with a good digital vom would be a good idea. Let your battery  
set for about an hour after turning off the engine and check the voltage. 13+  
volts is too high. A fully charged battery should read 12.6 to 12.8 volts. No  
more. So if you are reading higher, then maybe it's your voltmeter. But if 
the  reg is putting out too high a voltage, replace the reg. New ones are in the 
 $15-20 range and easy to change if you disassemble the alt.
