On one of our Texas trips in my son's '54 Stude wagon we were burning out 15 amp OD fuses. Like a idiot I started putting in higher rated ones. When we got to 30 it burned up the solenoid. WE went from Vegas to Kingman at 55mph, (that 4.27 to 1 gear set). After much searching and contact with local Studebaker guys we found a local shop that repaired generators and alternators. He took the cap off of the solenoid and we found it had a fusible link inside. He resoldiered it cleaned it and we were on our way. The problem was a leaky solenoid seal that gummed it up. #1. stick to the 15 amp fuse. #2. never throw an OD solenoid away. they can be fixed. A problem with the Studebaker version of the T 86 is that they used a 2 piece drive shaft and don't have a slip yoke on the output shaft. Yeah, lots of projects and little focus.
