for the past 2 months my 2000 range rover has been intermittently losing and regaining power to unrelated systems. power to all speakers (except driver's door), front passenger window, front passenger lock, rear tailgate and vanity lamp goes out at the same time. another day they may pop back on again then off again. i have checked all fuses (under passenger seat and under hood). i have checked the connections to the BECM. still have the problem. if i could see a wiring schematic or find out the color of the troubling wires, maybe i could make some head way. any ideas?

 

Check ground connections to chassis and body. (black).

 

have you removed the relays and actually look at the box under the hood, p-38 have a habit of eating fuse boxes.

have you downloaded the rave for a p-38, it should have digrams

 

i have spent quite a bit of time checking and pulling fuses from both fuse and relay boxes. i have disconnected and reconnected all the connectors going to the BECM. i have not checked any ground wires. i will check that next. i have downloaded a workshop manual for the range rover. (1360 pages with no schematics.
