I have read your other post thanks, have checked the MAF it works just fine (replaced with another working item and the result is the same), resistor also works, got hold of a multimeter today. starting as this request is about a fuel map printscreen from rovergauge not about the resistor...

Hi All, I have a RRC 4.2 v8 LSE running very rich on fuel. I think one reason could be the wrong fuel map applied by the ECU due to the wrong reading from the tune resistor (blue resistor 1800 ohm for my v8 4.2) Im using the rovergauge (https://code.google.com/p/rovergauge/) to check my engine...

Thanks. I have a blue one now fitted, but according to the fault log something is not ok. If the resistor is wrong, would my engine run richer than normal?

Hi All, I have managed to get the rovergauge connected to my RRC LSE 4.2. (great tool btw https://code.google.com/p/rovergauge/) the only fault I get when the car is running is "(21) Tune resistor out of range" The car is running rich, so I think this could be reason as the ECU tries to add...

I have changed my heater resistor today on my RRC LSE 1993. Its a pain as the space is just too small to unscrew old bolt from wrong resistor... You need a mini screwdriver and patience!!!!anyway its done so now I have all speed of ventillation:) .

Got my replacement Speedo Buffer relay (PRC8882) this morning. Fitted right away. I have made the volt measuring well on the components and wiring, as my speedo works now, indeed the speedbuffer relay was faulty ;))

thanks for the offer very nice of you. I have ordered a speed buffer last nite for few quids, and I hope that will solve the issue (though it will take 7 days to deliver, so I will update you within a week) if that doesnt help, I may consider your speedo head unit (if its from a 1992-1994 RRC)...

I hope! I had no idea on electrics before this, just reading the workshop manuals and ETMs I could find on the web and trying figuring out the electric wiring diagrams ;) Has anyone tested the speed buffer relay? how it should work when it gets the 12 V on terminal 85/86? or maybe its not a...

Some updates. Speedbuffer (5 terminal relay-ish thingy) seems to be wrong as it sends no signal onwards (on terminal 87, 87a) to speedo when terminal 85,86 energised (ignition on). I have tested this with a voltmeter and 12V from the battery. The speed buffer socket gets 12V from the...

121- speed transducer 184- speed buffer 186 - electronic speedo So looks like either te speed buffer or the speed itslef wrong.. Speedbuffer located at left side footwell. Any idea how i could test the relay once removed? Thanks A

Hi All, I have an RRC 4.2 LSE 1993. The speedo doesnt work, so I have decided to check what component could be wrong. I have checked that the transducer gets 12V when ignition is on (unclipped the wire and checked the green-white cable according to the electric diagram), then removed the...

Thanks!;)

today connected V8 vacuum pipes, sorted all (hopefully) electrics in engine bay... and started the engine, not all cylinders are running yet. speedometer / speed transducer still to fix... any tips where could I get a second hand (1993 RRC 4.2 LWB/LSE)? thanks

hi West Slope Rover, last question... Where your 2 tubes from the vacuum pump (front right wheel arch, just behind the left front lamp) go? on mine 1 goes to the break pedal with a side tube to the throttle activator, but no second tube out of the vaccum pump... (so the top outbound outlet is...

I give it a try , maybe it will run better :) I dont seem to have a canister between the washer tank an ld battery... Whats that for? (1993 lse 4.2) Thanks

Thanks! I thought the plastic ball (vacuum reservoir) on the left wheel arch should go to the recirculating/fresh air solenoid switch under the chubby box and the other on to te vacuum pump.... Maybe i was wrong... Thanks

Hi, I have a RRC 4.2 v8 which has 2 vacuum pipe coming out from the chamber. One goes into the distributor, but the 2nd one is not going anywhere at the moment, rhe pipe is closed. Where it ahould go? Also a few questions an 3 electric loose cables/plug whitin the engine bay.. -one small...
