#1 Ignition Warning Light will not Extinguish
Posted: Wed Nov 07, 2018 2:09 pm
My 1969 Series 2, 2+2 Coupe's ignition warning light will not extinguish.
I have had the alternator checked and it is working perfectly including 6-7 volt output at the AL terminal, I have also installed a new 4TR Control box (3 terminal variety) The charging system is functioning correctly despite the warning light not going out.
I have been advised to change the Lucas 3AW relay but, so far, I cannot locate it in the car. To date I have removed the fascia top, also off side and near side parcel shelves and associated under dash linings. The radio, speakers and mounting consul have also been removed together with the off side and nearside footwell linings.
Clearly I have now exposed much of the wiring areas but the 3AW is nowhere to be seen.
I read somewhere that the 3AW should be mounted below the heater matrix but definitely not there.
I have access to the workshop manual which gives various wiring layouts including an Addendum, "Supplementary Information for 4.2 Litre "E" Type and 2+2 Cars (Series 2)" Earlier wiring diagrams state that the 3AW relay was only installed in later cars but this qualification is not included in the Supplementary Information so I am assuming that it should be installed in my car! According to my research of these wiring diagrams if the 3AW is not installed the 4TR control box has additional connections (6 in total) My control box as stated earlier has only 3 terminals.
Can you give any advice on where the 3AW should/could be located or alternatively if no 3AW is fitted to my car, how I resolve the problem of extinguishing the ignition warning light.
ADDITIONAL INFORMATION ON MY CAR
The chassis number on my car, authenticated by Jaguar, is IR 41729 but the wiring diagrams that I have access to make no reference to this number. It was built as a LH drive and first sold in France by the dealer Delecroix to an American Airforce Pilot who took the car back to Palm Springs when he returned to the USA. I am the second owner having purchased the car in the late eighties and my understanding was the car was still in original condition, eg engine and gearbox numbers still match originals. Since then the car underwent a major refurbishment to concourse standards which completed in 1996. During the refurbishment the car was rebuilt as a RH drive and the refurbishment included a completely new wiring loom and clearly everything electrical has functioned properly until this problem with the ignition warning light. Regrettably the auto electrician that installed the wiring loom is now deceased. Mileage from refurbishment is only 4,200 miles non of which has been on wet roads.
In conclusion I have come up against a brick wall and any advice that you can give would be greatly appreciated
