I seldom drive the Defender (1995 NAS Soft Top) and the other day when I went to start it the battery was dead. No problem that's why I have a dual battery set-up. Throw the switch and the engine turns as normal but won't start. Hmm that's odd. I hook up my wife's car for a jump and the D90 will still turn fine (of course) but won't start. As I'm hooking up my wife's battery I notice the distint odor of rodents and further inspection shows a nest and droppings in the battery compartment of the D90. Dang Rats!
Looking over the D90 there is another nest and droppings under the intake plenum and possibly some bare wires going to the injectors. After 2 hours I've confirmed that the wires aren't chewed through and I've reinsulated the slight gnawing marks with electrical tape.
Still won't start. (It cranks just fine).
Look under the instrument binnacle and darn it another nest and droppings behind the dash. Another few hours (half a day) and I've inspected the wires. Luckily none were gnawed through but there was quite a bit of wire insulation damage. So, I've taped it all back up nice and neat. Well, as nice and neat as electrical tape will look.
Still won't start.
It appears that I'm not getting power to the fuel pump. I don't see any voltage to the fuel pump fuse. When I jump a wire from the lights to the fuel pump then I can hear the pump spinning. So, like I said there appears to be a fault between the battery and the fuel pump fuse.
It appears that the thick white wire with blue stripe should be carrying current to the fuse. Back tracing the thick white wire with blue stripe (WH/blu) it looks like that comes from the inertia switch cut off. Leading into the inertia switch is a thinner white wire with purple stripe (wh/pu).
I also don't see any voltage across the inertia switch (Wait, I need to double check that). Does anyone know where the wh/pu wire comes from?
My memory says that on cranking, the fuel pump is energized for 5 or 10 seconds so there must be some type of clock mechanism. Is that clock before or after the inertia switch (Maybe it is in the relay.)
But my question is does anyone know where the white/purple wire comes from that goes into the inertia switch? Or, can you offer any other advice? Yes I have a gun and yes there are now 5 dead rats outside of the barn.
My Rover is mad because I haven't been driving her lately.
