Allan,
Using the start position on the ignition switch may be putting a load of 
as much as 30 amps on that component. Why don't you try the Ford 
solenoid, using it just as a large relay on the firewall that is 
activated by the ignition switch being in the start position. Supply the 
S terminal on the Delco from the Ford solenoid. I think you may just be 
pulling too many amps through the poor old ignition switch, and/or the 
poor old bulkhead connector.
