Don Del Posted February 17, 2012 Share Posted February 17, 2012 I am looking for a part number for the low ratio engaged switch on my '99 V8 Defender 110 Station Wagon. I haven't got round to taking it out yet but I know it is definitely stuffed. Is the switch the same as the diff lock switch - PRC2911? I have checked various parts manuals and can find no reference to the switch. The last eight digits of the VIN areXA159828. Cheers, Del Quote Link to comment Share on other sites More sharing options...
western Posted February 17, 2012 Share Posted February 17, 2012 there isn't a low ratio switch, only the diff lock in switch that lights the symbol on the warning light panel, low ratio engaged is shown by the position of the lever/knob.

Don Del Posted February 17, 2012 Author Share Posted February 17, 2012 The switch is located below and to the left of the reversing light switch. In the Haynes manual for '83-'07 diesel Defenders it is referred to as a "low detect switch". If you have a copy of this manual it is on page 7A.6. It is there on my vehicle and disconnected and it is definitely not the diff lock switch. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted February 17, 2012 Share Posted February 17, 2012 Not sure what you are refering to... what has given you the sign that 'this' has failed? Quote Link to comment Share on other sites More sharing options...
Don Del Posted February 17, 2012 Author Share Posted February 17, 2012 Not sure what you are refering to... what has given you the sign that 'this' has failed? The switch is disconnected and from the state of the plastic around the connectors it is clearly stuffed. I suppose I could bridge across the contacts in the disconnected cable coupling to see if any warning light comes on. It looks as though I was wrong in my initial description of the function of the switch but the fact remains it is there and as I have already said Haynes describes it as a "low detect switch". But what low??? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 17, 2012 Share Posted February 17, 2012 Is it possibel you have a Borg Warner transfer box rather than an LT230? This has a temperature switch, which sort of matches your description.... Quote Link to comment Share on other sites More sharing options...

Don Del Posted February 17, 2012 Author Share Posted February 17, 2012 is this switch on the main gearbox ? which gearbox manual R380 or auto ZF ? Manual R380 and the switch is on the main gearbox to the rear of the diff lock lever. Quote Link to comment Share on other sites More sharing options...
Don Del Posted February 17, 2012 Author Share Posted February 17, 2012 Manual R380 and the switch is on the main gearbox to the rear of the diff lock lever. Thinking about it wouldn't that put it on the transfer box? Quote Link to comment Share on other sites More sharing options...
western Posted February 17, 2012 Share Posted February 17, 2012 Thinking about it wouldn't that put it on the transfer box? Nope, hi/low/dif lock lever is on the housing above main gearbox, are you able to add a photo of the subject switch, I can't find any mention of one in my info to hand.

Retroanaconda Posted February 17, 2012 Share Posted February 17, 2012 Td5s have a high/low range switch, since the OPs vehicle was built in the Td5 era (just) its quite possible that it was included on his V8 model even if it isn't used. Especially since it's an export model. Is the V8 ECU-controlled or is it carbs? If it's ECU then it will have a feed from a high/low sensor to adjust throttle response just like a Td5.

I think we might be getting somewhere! The engine is on carbs. Quote Link to comment Share on other sites More sharing options...

My switch is located on the right hand side. Also further to Retroanaconda's post is it of any practical use on my vehicle? Quote Link to comment Share on other sites More sharing options...
western Posted February 17, 2012 Share Posted February 17, 2012 looking at your page the left hand picture actually matches the location as on my attachment above, the orange arrow is the difflock linkage the blue is the front output housing. any reference to left or right should always be the vehicles left or right as sat in the driving seat or stood behind the vehicle facing forwards that way the convention is always the same & prevents confusion. probably of no use to your vehicle, but it serves a purpose as a blanking plug to prevent any transfer box oil leaking.

In referring to the right hand side I used the convention you refer to. I think you are right, it is just serving as an expensive blanking plug! Many thanks to you and the others answering this post. At least it is one less job for me to plan for. Quote Link to comment Share on other sites More sharing options...
western Posted February 17, 2012 Share Posted February 17, 2012 glad we managed to find the part concerned & establish it's of little importance to the running of your vehicle. just terminate & secure the unused wires safely. Quote Link to comment Share on other sites More sharing options...
