Pre-war (up to 1942) 1941 Cadillac adding Condenser to Generator

[J. Russo]

Hello,

I'm considering attaching a condenser to my generator. I have a spare from my distributor. Can I use that condenser or is there a special one I need to find?

Thank you

[Jay Friedman]

My 1935-55 Master Parts List shows the 1937-55 radio condenser on the generator is part number 191 1095 and the 1934-55 distributor condenser is part number 186 9704.

    I did some checking on how to get rid of noise on a radio. 
   from a 1949 Delco radio book Part #6030 is the universal condenser for use on a generator, any make ,any year.It  is rated .5 mfd (microfarad).  From a P&D ignition parts section on  radio condensers  "For best results ,use highest capacity of above condensers whenever space and conditions permit" It sells 3 models ..25 mfd,.5 mfd and 1.0 mfd .
   In 1953 Delco also sells #6030 for use on Voltage Regulators, Ammeters and Ignition coils.  Earlier there was a model #6017 for Cad,Buick and Olds that fit inside the coils w/caps.
 Other ideas are  Front wheel static Collectors.
 Noise Suppressors on the distributor.Delco says For 1941,42,48 and 49. One that goes between the cap and coil wire (25,000 ohms). For 1946 -47 on each of spark plug wires (15,000ohms)


I could not find the condenser rating for 41 Cadillac directly. A Chevrolet that uses the same after market condenser says .28-.32 mfd.  Filko an after market company says .17-.23 mfd. They also say  high speed long drives ,lower capacity. Slow around town use higher capacity.

The exact capacity is not very important.  Worry
more about the suitability of the cap construction
for this type of service, AND keep the length/cross
section of the loop between the cap wires and the
gen minimized; this is the remaining antenna of
radiation. 

The cap can only go on the gen output, no cap can
be used on the field terminal (to avoid reg contact
damage).  So that wire from the field to the reg is
an antenna.  Some installs avoid this by mounting
the reg directly on the gen case, minimizing the
field wire.   Another approach is to use shielding
from the gen out to the reg, a messy process.  I
used aircraft ign shielding on my 62 to eliminate
ign noise, replaced the gen with an internally
regulated alt for mobile amateur radio.
