Overdrive Fuse Installed (70 MGB)

During a Zoom Seminar, John Twist recommended that an in-line fuse be placed between the OD switch and the overdrive solenoid in wiring harness which terminates under the hood.

I took a section of 18 gauge Yellow wire from an old wiring loom and created a fused section with bullet connectors on each end. I like this idea because I could add it to the circuit, or remove it without actually cutting the existing wires.

Note: John Twist's Technical Zoom Seminar #324 dated 5/10/2021 @ around 2 hrs 18 minutes recommended a 10amp fuse.

When I drove MGB# 79 at the1970 Daytona 24, we were using overdrive as well, and our chief mechanic told us to use the clutch on up-shifts, and down shifts on the overdrive unit. We finished the 24 Hour with no clutch, or gearbox problems. Use the clutch!
