Hi Garth, have you managed to,set the lights up? I would be interested to know how. Thanks

I have a GoPro3 Black and when I filmed from inside a saloon the advice was to switch the spot meter on due to the contrast between the dark interior and the bright exterior. As the Caterham is very much open to the elements should I leave the spot meter switched on or not?

Hi Jonathan, Thanks for the reply. I will give these ago, but am on my way to work. Re. 2. I will check the sensor / switch, but anticipate it is fine as the fan didn't come on immediately and when it did switched itself off apparently normally. Re. 3 I will take her for a drive and see what happens during a run. George

I was tinkering in the garage this morning and whilst doing so let the car warm up,as it hadn't been run for a while. The ambient temperature was only about 3C. After about 5 - 10 minutes I noticed that the radiator fan kicked in, but the indicated water temperature was still only just reading on the gauge so in the very low 40's. If that is correct the fan shouldn't have kicked in. I had a fiddle with the plug at the rear of the gauge without any change in teh reading; historically my water temperature gauge has intermittently read low but by moving the plug / wires has given a higher (presumably) correct reading. My 7 is a 2000MY 1.6 EU2 Super Sport K-Series engined car equipped with an Apollo tank so the water gauge also shows the oil temperature at a flick of a switch. The oil temperature was not even registering; which is what I would have expected as the car had not been running very long and the ambient temperature was low. Can anyone explain why this happened?

Thanks everyone job completed. For anyone wondering, the change lights plug into the bottom of the ACES Control unit and are easily removed.

Great news ECR that was what I was hoping. Thanks.

I know, I posted one set! Unfortunately no schematic / wiring diagram...

Planing to remove my scuttle and have ACES2 change lights fitted. Does anyone know if the change lights loom is disconnectable from the main unit? Am away from the car so cannot check myself.

With regard to the ACES unit this may help: http://www.aceserve.co.uk/new04/userguidess.html

Thanks for planting the seed for a removable scuttle! I now have a winter project! Can I just clarify you mean 12 rivnuts and not 24; having removed 24 rivets from the bulk head doesn't that mean I would need 24 rivnuts?

Hi Bio, the engine is fine in normal driving but when stationary the gauge shows 100 degrees which is unusual for my car. Seven & Classics went over the engine today and gave it a clean bill of health.

Thank you for all your advice. This morning I carefully checked everything and found nothing untoward. So I rang Seven & Classics who suggested I popped in for them to have a look. What an excellent outfit they are. Brian Attwood examined the cooling system with the engine running and using an infra red thermometer confirmed that everything was working correctly including the fan switch. The conclusion was that the higher than normal reading was most likely due to the high ambient temperatures aggravated by being held stationary in traffic for a prolonged periods so that heat sink from exhaust primary(s) directly below the water temperature sender caused the under bonnet temperature to rise significantly.

Right! WIll check the fan tomorrow! Have ordered a new cap and sender unit; I found a post by SM25T indicating that the cylindrical sender connector uses the same connector but mounted at 90 degrees. DJ. - When moving the temperature sits at 80 degrees as normal. The front end was recently stripped down to have the suspension powder coated so will check the connection tomorrow. Jonathan - excuse my ignorance but where is the fan sender and how do I short it? Testing the fan: Presumably this is as simple as the fan should be blowing air from the rad into the engine bay and NOT back through the radiator?

Jonathan - Is the fan pushing the right way? I will check. Is the electrical connection two way; so it could be connected incorrectly reversing the motor? Will have a look tomorrow as I am currently nights. SM25T & Bio - The fan cycles apparently normally and comes on when the water temperature reads just over 80 degrees (presumably a 82 degree thermostat). I have ordered a new expansion bottle cap and will order a new water temperature sender although I need to speak to Caterham parts as the new sender unit uses a cylindrical connector as opposed to the usual blade one; and I am not sure what connector it now takes. I will check the hoses tomorrow, paying attention to the heater hoses. Thanks
