Question
QUESTION: HELLO I have a 1992 Range rover country Gear Selector interlock issue
I can not get the car out of park  (sometimes it will work)
I have checked the solenoid it is working fine when i jump in 12v+ to the red wire
the brake switch is good but jumpered it for testing
brake stop lamps are working  
I can read electrial prints but I can not find it in the prints listed in the 1990-1994 workshop manual can you help?

ANSWER: Hi Dale,

so you tested the solenoid tranny/transfer gearbox interlock and it worked ok.  How about the inhibitor and reverse light switch?

QUESTION: Yes both test ok ... is this solenoid in the prints anywhare ?
I am sure it is something simple loose conection switch or?
and I am sure I could find the problem if I had some prints to go by

Answer
Hi Dale,

I only have the classic Range Rover workshop manuals '95 +  Do you have this workshop manual too?  You could try this manual electronics section.  Many parts on the Series I Disco were found to fit on Range Rovers, perhaps the electrics will to.
