The Diamond T 4 ton 6x6 trucks (such as the wrecker) were 6 volt system/12 volt start and used a large series/parallel switch mounted through the floor under the drivers feet. They had two 6 volt batteries in the system.
The switch was quite large as befits the amount of power it handled to turn over the 529 cubic inch engine.
Somebody may have one kicking about.
Condolences on your loss of family members. It is quite a tragedy to lose people you respect and like and they take all their knowledge and wisdom with them.
