Paul aka technozen. https://www.technozen-electronics.co.uk Well known in rover circles and I've used his services myself I can recommend Paul as well, very helpfull and good prices.

Thank You

What is the significance [if any] of a flat front lens please?

Sold thank you

2 caterham branded leather Seats with runners from my roadsport SV. These are in good condtion but there are 3 small and one large scuff on 1 seat, and 1 small scuff on the other. This has removed the black finish, and was presumably caused by the seat belts. See photos, I am sorry they are upside down. £800 unbranded from thundersport without club discount. Im looking for £250 for the pair.

Hi Jonathan Its not quite that simple, certainly from someone who has only a basic understanding of electrics. The speedo is actually now wired exactly as the K series circuit diagram https://www.graduates.org.uk/docs/201626_EU3_wiring.pdf However that only works because Caerbont have added the internal resistor and a 12 v feed out from pin 8 of the gauge. As I understand it, the gauge is wired and configured differently depending on the sensor, ie gearbox or wheel. The resistor could be fitted externally to the gauge, and I suppose it wouldnt be difficult to wire in a 12v supply, if you understand what was required. The installation would be different however with a different sensor. Hope that makes sense

Thanks to Caerbont, we finally got this resolved. My K series has two wires from the gearbox sensor, a red and blue which is connected to the output from the gearbox sensor on one end, and to pin six on the speedo plug on the other. The other wire, light green, needs a 12 volt supply, which Caerbont added to the internal wiring in the speedo connected to pin 8. They also added a 470 ohm resistor between pin 5 and pin 6 as that is also required for the gearbox type sensor.

The resistor supplied by caerbont was 470 ohm, the one shown is a 68 in chrisc post. I guess we wont know if the installation was damaged until tom refits it tomorrow. Thanks for your suggestions

Hi Jonathan I don't have a wiring diagram for the resistor, only that it has to be mounted from the speedo signal input to ground I dont have these WN460 - Rear ARB and Wheel-speed Sensor WN572 - Speedometer sensor groundwire installation And the original speedo was re installed and working after I couldnt get the new one to work in February, and has been in situ and was working up until yesterday when in went into the garage, so I am pretty confident the wiring is ok

Yes the old one is fine, and its driven from the gearbox

My 2003 7 speedo has always read 10 mph higher than the car is traveling. After contacting Caerbont,I tried re setting the dip switches to no avail, and after messing about they suggested I replaced the speedo with the latest version so I ordered one. I thought that this would be a relatively painless change, but after fitting it, and trying to calibrate as per the instructions, I tried to calibrate using the Drive to set facility, and although I could access the DTS screen, and select the 00000 option, after driving one mile, the display remained at 00000 and then reverted to set ppu. In addition, although the needle twitches, it did not deflect full scale when switching on while pressing the reset button, and although there is a default set of 008380 the needle does not move when the car is driven. I went back to Caerbont, and they told me that they thought that my speedo was driven from a gearbox mounted speed sender. This is an unusual sender in that it requires a 470 ohms resistor to be fitted from the speedo signal input to ground. They sent me a resistor, and along with some other work I asked Tom New he could fit the speedo for me. After wiring in the resistor, ~Tom has has had about as much luck as I did. Before i give up and send the new unit back, is there anyone who has done this or is able to offer any suggestions. Many thanks

thank you Steve

Who is Jim in Portsmouth please

I replaced a 2003 Banner battery last month, I didnt recharge it until the battery was flat, although during the winter storage I turned the master switch off

It was Jemma that I dealt with and she seems to know her stuff. The Thundersport web site doesnt show the hood with the zips but their ebay listing does and it wasnt a special. http://www.ebay.co.uk/itm/Caterham-7-Series-5-SV-Half-Hood-Easy-In-Vinyl-/180937271012 The side straps do have an adjustable buckle but the free end has a velcro tab on the end and that was too long to mate with the secures end. I expect that they have modded their drawings to suit. I was quite impressed
