<VV> more on coil voltage

[BobHelt at aol.com]

Ray,
It sound like you are getting some bum information. Here are my suggestions 
 to get it running right.
1)   Forget trying to troubleshoot both the ignition and carb  systems at 
the same time.
2)   Concentrate on the ignition system first.
3)  Temporarily reinstall the points to get this set up  correctly.
4)  If you have a harmonic balancer verify that the chisel mark is  still 
verifying HB integrity.     Set the HB or  pulley to 8 degrees on the timing 
scale with the rotor pointing to the #1 plug  wire  (you do have the plug 
wires in the right firing  sequence don't you?)
5)   Loosen the dist and set it so the points are just ready to  open for 
plug 1
6)   Disconnect the coil and measure its primary resistance. If  it 
measures 1.5 ohms or less, you want the     ballast  resistor in the circuit. if it 
measures more than 1.5 ohms, you do not want any  ballast resistance in the 
circuit. 
7)   Hook up the coil as follows. black wire from the distributer  goes to 
the - coil terminal. Original coil wire goes to the + terminal if  you want 
the ballast in the circuit. Otherwise find the ign switched +12v source  and 
connect that to the + terminal. Connect the Pertronix 1 red wire  to the 
ign switched +12 volt source.
8)   With the points OPEN, and the ignition switch on but with  the engine 
not running, measure the voltage at the + coil terminal. It  should be 12 
volts battery voltage.
9)   Now rotate the distributor slightly to close the points.  measure the 
voltage at the + coil terminal. It should read +12 IF there is no  ballast 
resistor in the circuit. BUT if there is a ballast resistor, then it  should 
measure about 5 to 6 volts (with a res wire. A res block may have a  
slightly higher voltage). If not in this ballpark then there is a problem  
somewhere.
10)   Assuming that all went as planned here and you got 5-6  volts at the 
+ coil terminal , reset the points by turning the distributor so  that the 
points are just ready to open firing #1 plug.
 
Try it and see how it runs. Reset the timing with a timing light and  
tighten down the distr..
 
Let us know. if you need carb info we will follow it up later, 49 should be 
 Ok as they don not affect idling.
 
Regards,
Bob Helt

To he  who said "90% of carburetor problems are ignition!":  As of tonight  
I
have...  6 month old plugs I cleaned (they weren't bad) just  yesterday, 1
year old Seth Emerson plug wires,  1 month old cap and  rotor, 1 week old
pertronix I, 1 hour old coil and RU-4 ballast resistor  (you guys were
right, with the new resistor it still reads 12v on the side  of the coil
wired to the car -as opposed to the side connected to the  distributor-
someone said I might be measuring on the wrong side).   The pertronix is
running on a "full voltage" line I installed for it as the  instructions
told me to  do.
