I have a 2006 range rover the suspension has dropped in the rear I tested the fuses in the rear of truck fuse 17 for the suspension is not getting power what is the issue thanks
Generally there is a main breaker, fuse or fusible link supplying a bunch of circuits which mostly are also fused. Some of those fuses are live all the time, some are live when the ignition and/or accessory is on and some are live only when the particular circuit is switched on - the power being supplied first to the switch and then to the fuse.
When the cause of a fault isn't obvious a wiring diagram is necessary especially with a computerised vehicle - it is important to see how a circuit is supposed to work, especially with modern vehicles as many circuits don't work in the conventional way.
