Yup.
Old Jeeps are particularly susceptible to ‘bad ground’ syndrome.
I only have one right now, a 1971 Jeepster Commando (with the Buick Dauntless “Oddfire” V6) and it is definitely in need of “treatment”. I’ve been trying to find the time for the last month.
Haven’t seen a Commando in years.
Sometime back when I had to endure the Jonesboro storytelling festival a few years in a row, going into town at a small garage was a Commando that never got touched.
It was in the same spot with the same flat front passenger tire.
Just about all of signals on that old Willys were gone and I’ve run wire, crimped, heat shrank quite a few spools.
That is also throwing in modifications and upgrades of my own.
