Outer Limits 4x4 Board

Ok I have a 93 nh pajero and the front lights are flashing

so I replaced the vac hoses and it still does it then I checked the vacuum and in 2h I have vacuum present at both solenoids and in 4h only on 1 so does anyone else have vacuum at both solenoids while in 2h or know what's wrong cheers ace...

G'day Ace.
I had the same prob a few weeks ago; This was Bitsamissin's reply.

"Neil sounds like it is an electrical issue.
Most likely the free wheel engage switch either needs replacing or cleaning (bad connection).
This is located next to the actuator rod and if you remove your bashplates can see it clearly. This is the first place to start rather than diving in and replacing the 4x4 ECU behind the dash. Also pays to check the two vacuum solenoids (located just behind the air filter on the wheel tub) to make sure none of the hoses are split or leaking and all connections are good. It only takes a small amount of crap in the wrong place to upset this system so it pays to acquaint yourself with it.
If you buy a Gregory's manual (No- 510) it explains it pretty well. Most of the flashing lights issue's are more annoying than anything else."

Neil

P.S. If you have a Greogory's 510, it's page 170.

I really don't think I have anymore to say on this subject.....................

Sorry.

Thanks guys I will check the free wheel switch. My problem is I believe is one of the vacuum solenoids as one is allways on and when I unplug the hose off one of them the lights stop flashing but it then doesn't go into 4wheel drive then
