We have a 2001 Discovery2 with an under-hood fusebox issue.

Upon replacement and ignition being turned on, the fuse immediately pops. We have the wiring diagram but it is very hard to follow/confusing. So far, we believe F2 is related to:

EGR Mod
EGR Throttle
MAF Sensor
and all 4 HO2 sensors.

Any help is appreciated.
