Yeah but fuse links are either good or they are not. Intermittent problems are generally not associated with them.
HA!
I've got over 20 years experience with a 92 D250 that begs to differ.
When they get old and crusty they sometimes work and sometimes don't. Every now and then the systems backfeed and pull power from weird places.
Kinda like when I hit the power window switch and EVERY warning light on the dash lit up. ABS, brake warning, water in fuel, wait to start, and all the others would light. I fixed that one and the same thing would happen when I tried to turn on the A/C blower.
