Re: 1955 & 1956 Starter. Delco or Autolite interchange

Glad the MN parts man had a starter available. As Ross pointed out, the Delco solenoids pull quite a bit more current compared to the Autolites. With the 55-56 (and even the 54) key start ignition switches being somewhat low capacity in the starter contact department and starting to be expensive and harder to come by, it wouldn't hurt to take a bit of that heavy current load out of the switch.
There have been some reports that adding a relay to operate the solenoid was a factory suggestion but I have not come across any documentation to that effect -- although It may be in some of the Stude bulletins that I don't have.
Here is a diagram I threw together of what needs to change if anyone wanted to add a relay. One of the 4 pin 30 amp cube type relays available from numerous ebay vendors could be mounted inline behind the dash where it would not be noticed or it could be placed at the solenoid too. Either position would work with the only difference being if the neutral safety switch or relay on cars so equipped was before or after the relay. The added battery connection could be picked up easily at either place.
