I have not been all that impressed with the headlights or sub looms in the light pods of my G40. The sub loom seams to corrode very quickly and fail. in part this appears to be because a bulkhead fitting is used on the sub loom with no boot on the back of it letting water into the connector. has anyone tried a different connector i.e. superseal?

Also has anybody else seen the 90 mm LED module L4060 range of hella lighting (https://www.hella.com/bus/en/Lighting-1652.html) I'm considering swapping my dipped beam, side marker light out to the LED equivalent if i can get some more information on the weather proofing. Has anyone got experience with the units?

I have looked at swapping all the lights and reconfiguring and gave up. The problem is that the main beam unit as fitted has a shallow depth of body behind the light. I bought a set of the 90mm dip / head lights and they are twice the depth and the mounting ring is in a different location in relation to the lense. This could be overcome, but the problem then is that He back if the light hits the wheel.

I am replacing all mine with standard spec items but have invested in the rubber boot seals for the back of the lights.

Ideally it wants a removable fibreglass inner panel over the back of all the lights.

What about the front wheel arch liners that are in Ginetta’s parts list, I’ve never seen a car with these fitted though?

An update on my lack of Main Beams:

I have now checked all wiring on the engine side of the bulkhead and there are no shorts etc at either the lights or any of the loom back to the bulkhead.

I therefore cleaned everything up just in case and reassembled. I ordered a new canbus interface box from Ginetta and as far as I can tell this box modifies the low voltage from the stalk switch to 12volts, that then triggers a traditional relay.

Anyway after more messing about I managed to replace the canbus box in the car. Powered up, pulled the stalk and hey presto main beam lights.... for about 5 seconds... then flickering lights, smell of melting electrical components and then nothing.

Assuming something must be shorting, I dropped the fuse box again only to find all fuses still intact.... after a bit of tracing back the smell, I feared it was the new canbus box that I had just installed. Sure enough, I opened it up to find one of the chips completely burnt out.

Now I am stumped. I cannot work out what would cause this other than a fault on the stalk I guess? Down stream of the box seems to only trigger the relay although I guess the relay could be knackered but even so I am not sure how this could do anything other than not switch the lights on.


The problem I have is that the wiring diagram I have for the car appears to have only 6 relays on it, my car actually has 12 relays. The diagram & numbering of both the fuse box and relays and some of the wires in my system bears absolutely no resemblance to that of the wiring schematic and so I am well and truly stumped.

Car is now sat without an MOT as I cannot figure it out and I am now £100 lighter for a second burnt out canbus box and facing having to buy another, but fearful of this being a costly exercise as I need a working box In the system to send a trigger signal to the relay so that I can try and locate the fault, but at £100 a go this could get very expensive.

Has anybody me else had trouble with this system?

Mine dont work either (never have) and I am hoping replacing the headlight unit will fix it as they are in a terrible state.

Once I get the new ones I plan to get some rubbers or something from the scrapyard to protect them a little better.

Need to clean up the wiring to headlights in general to be fair as in a terrible state from the spray off the road etc.

Hoping mine is just the state of the lights causing the issue but either way, they need replaced.

Cheers,

Dave

I have ordered some of these in the faith that I might get them working before I torch the car:

Does anyone have the Hella part number for the dipped and main beam units?

Look like the dipped and sidelights but I'm struggling to find the main beam units.

I have just replaced all mine and have all the numbers and links.

Those in your link are not quite right. Will post up tonight or tomorrow.

Thanks, I replaced my dip beams 6 months ago with bits from the factory. As I did not fit the rubber shields they are now pants again.
