Jim 123 Posted February 17, 2019 Share Posted February 17, 2019 Timing of our postings is a bit out of sequence. I revised #49 as it loaded with a delay. Is the fan fuse OK? Link to comment Share on other sites More sharing options...
CtrMint Posted February 17, 2019 Author Share Posted February 17, 2019 I replaced the 10A reverse/brake fuse and pressed only the brake pedal, the lights worked and the fuse didn't blow. Reverse light remained disconnected.So it seems its related to the reverse circuit.Weirdly the brake light brilliance is inverted to the rear lights, the one which was dimmer has a brighter brake light.Wrt the fan, I believe its the green 30A in the earlier photo and yes it's fine, tested it with a multimeter.

bosshogg Posted February 17, 2019 Share Posted February 17, 2019 Sounds like one of the brake/side bulbs in the rear light unit may be the wrong way around, the one that dims on braking just needs turning 180 degrees in the bulb holder.

bosshogg Posted February 17, 2019 Share Posted February 17, 2019 Re the reverse fusing, in post #48 you say that you disconnected the econoseal plug to the reverse switch, tried the brakes and then put it in reverse and the fuse blew. Had you reconnected the econoseal when you did this? Link to comment Share on other sites More sharing options...
CtrMint Posted February 17, 2019 Author Share Posted February 17, 2019 Sorry not following you there? turning 180 degrees? Link to comment Share on other sites More sharing options...
CtrMint Posted February 17, 2019 Author Share Posted February 17, 2019 I disconnected the econseal plug to the reverse light, at the back of the car, not the reverse switch which is by the gear stick.I didnt reconnect the light plug. Link to comment Share on other sites More sharing options...
bosshogg Posted February 17, 2019 Share Posted February 17, 2019 Assuming you have standard bulbs and not led rear lights, the brake/side light is one bulb with two filaments, one contact for each filament. It sounds like one of the bulbs has its brake filament contact touching the side light post, so if you take the bulb out, and turn it around so that the contacts reverse it should correct the problem.

CtrMint Posted February 17, 2019 Author Share Posted February 17, 2019 OK, I take it the brake light should be the brighter?How much of the light needs to be dissembled? Link to comment Share on other sites More sharing options...
bosshogg Posted February 17, 2019 Share Posted February 17, 2019 Usually just remove two screws holding the lens on and then you can take the bulb out. As above it will be the side that dims when you brake that needs turning. Yes brake light is brighter. Link to comment Share on other sites More sharing options...
CtrMint Posted February 17, 2019 Author Share Posted February 17, 2019 You were correct over what was wrong, although I couldn't see how to solve the issue on the light as you describe. I pulled the light out from the car, disconnecting the Econoseal plug. I removed the yellow insert and swapped the Red and Green/Purple wires over in the plug. This solved the issue. The rear brake lights are now equal on both sides and the most bright, using the same filament, the foremost I think.The rear normal lights, sorry not sure on their official term are also now equal and using the same filament.Thanks for that.....Just need to sort the reverse light fusing issue and rad fan now.

bosshogg Posted February 17, 2019 Share Posted February 17, 2019 If as Jim says there are two connectors at the gearbox end, I think you need to check that it is connected to the right one. (Easier said than done probably)! Link to comment Share on other sites More sharing options...
CtrMint Posted February 17, 2019 Author Share Posted February 17, 2019 I took a picture, of the connections at the time, but didn't photograph how I connected.If I recall it was the black connection at the back. I thought it was the only plug that was compatible with the loom to be honest.The tunnel top is pretty tight, do you know if you need to remove the seats, to get the tunnel top up?

bosshogg Posted February 18, 2019 Share Posted February 18, 2019 I don't know the answer to that I'm afraid. Hopefully someone who does, will be along shortly to tell you if the black one is correct. Link to comment Share on other sites More sharing options...

Jim 123 Posted February 18, 2019 Share Posted February 18, 2019 The black connection is the correct one. Maybe before you disturb the tunnel top it would be worth doing a few checks for continuity around the reverse light assembly? Link to comment Share on other sites More sharing options...
CtrMint Posted February 18, 2019 Author Share Posted February 18, 2019 Did I also mention the number plate light doesn't work, that was pre-fitted. It seems to be directly wired into the loom too. Link to comment Share on other sites More sharing options...
Jim 123 Posted February 18, 2019 Share Posted February 18, 2019 Mark have a look at page 165 of the pre Ikea Manual re the number plate light and do a check. Link to comment Share on other sites More sharing options...
CtrMint Posted February 18, 2019 Author Share Posted February 18, 2019 I did read it, but I felt it was talking about a bulb type rather than the LED style I have. Link to comment Share on other sites More sharing options...
ChrisC Posted February 18, 2019 Share Posted February 18, 2019 Yes the LED rear numberplate light is new from August last year, and looks like the wire is pre attached, but it must be connected into the loom somewhere?https://caterhamparts.co.uk/rear-lights/6979-lampnumber-plateled-08-18.html?search_query=number+plate&results=118 Link to comment Share on other sites More sharing options...
CtrMint Posted February 18, 2019 Author Share Posted February 18, 2019 I'm going to separate out the threads, will make more sense. Link to comment Share on other sites More sharing options...
Jim 123 Posted February 18, 2019 Share Posted February 18, 2019 Why not open up the casings of the number plate and reverse lights and check the integrity of these units with your meter as a first step? It would be interesting to clarify if you have fixed the differing intensity of the tail light / brake lights. The number plate light will take its feed from one of these.2 other things to consider. From memory there is a small earth that has to be fixed to the fasteners of the RH rear wing below the boot floor. Also have you confirmed that the rear fog is working.

CtrMint Posted February 18, 2019 Author Share Posted February 18, 2019 Scratching off the powder coat around the screw hole receiving the eyelet fixed this.The screws holding the bracket also had a good earth and powered the light too. Jim,I don't believe the intensity issue was a grounding issue, as I could see different filaments being used when the lights where on and the brake pedal pressed.For example, the brake light on the left used one filament, whilst the brake on the right used the other, hence the differing intensity. Swapping them around fixed so they used the same filament on both sides. Now I know I'm far from knowledgeable, but surely that one is fixed??

CtrMint Posted February 18, 2019 Author Share Posted February 18, 2019 Quick status summary of the issues. Radiator fan... still not working, been up to 107c according to OBDII coolant level. Reverse light - blows fuse as soon as reverse is engaged, reverse light currently disconnected. Rear light intensity - fixed, the incorrect filament in use on one light, brake and rear light transposed. Number plate light - fixed, grounding issue on the bracket, powder coat removed. ( https://www.lotus7.club/forum/techtalk/led-rear-number-plate-light-not-working )I'd like to get the reverse sorted now, will separate to another thread, Thanks again for all the support.
