WB testing problems

[Stephen Andersen]

Okay, I am testing out my assembled WB board using the 
www.diy-wb.com instructions.  I worked up thru step 14, 
but I ran into a wall at step 12.  Measuring from pin 
5 on U3 to J12, with 14 volt input, I get 6.75V.  
According to the instructions, I am supposed to get 
7.9-8.0 volts.  It says to check R38, C12, and ISO1.
Since I dunno how to check C12 or ISO1, I replaced
them with extras.  I also checked R38 and got 98k Ohms.
It is supposed to be 100k.

Anyone got any ideas?  Everything thru step 14 checked out
great.  I am lost!!!!
