xjs v8?

Just so everyone knows what the 4 wire Hall Effect rotor looks like here is a photo, picked one up today, magnet is clearly visible on the opposite end of the firing terminal, on the underside, clearance between board and magnet is quoted as 30 to 90 thou of an inch... Hopefully this will enable the engine to continue running after the initial thermotime firing of the cold start injectors...................
By for now, Art

Thanks to all so far here and Jag Lovers everywhere......... I believe I have the wrong rotor.... I need the one with a trigger for the 4 wire Hall effect board . The original was broken by me when I was trying to dissemble the siezed up parts of the distributor..
Does anyone know what year they started fitting the Hall effect 4 wire trigger boards........
Best Regards, Art

HI William, Andrew,David and the rest of the Boys,
PS, this actually is a Bosch unit... I have wired as per above, there is now actually two red / white going to 86, the one wire actually has a piggyback attaching terminal on it .
The engine now starts on the CS injectors I guess, buy stops in a couple of seconds.... The main injectors I imagine are not being energized.......is there something wiring I am forgetting to attach....hey at least it runs after heads, distributor etc were removed and rebuilt...... Art

Allright ,now that we have White Purple it is an earlier car. It should be; WP x 2 from CSR 87 (C2) to CS injectors; WR from 86 (W1) direct to TT switch; WG from CSR 85 W2); Of course your (6RA) relay has the lucas markings and these numbers are the International system, so the corresponding lucas number is in parenthesis The MISSING LINK is the NS brown/Slate pos feed from the pump relay 87 (C2) to the CSR 30 (C1) BTW,the diagram Nois WD177/1E, good luck, my previous caveat still applies.

Brothers,
this time I will give you a photo, just remember I am a cabinetmaker not a photographer...........the thermotime wire has been connected , it has a plug sim to the fuel injectors. so here we are,2 wires together white and purple,on a female spade connector,
1 wire one a female spade connector white and green, and the other wire white and red with a female spade type connector.
Photo also shows main relay with only 2 wires attached as of right now....
I firmly believe these three spades belong on this item... Art

Art, it appears that those wires go to the cold start relay except there should be one other, the feed from 87 on the pump relay to 30 on the cold start relay this should also be the feed directly to the pump! PK is from 87 on the CSR to the injectors (2); WR is from 86 on the CSR to the thermotime sw & ECU/St Solenoid; and WG is from 85 on the CSR to the thermotime switch. As you probably know there were continious changes due to ongoing development so double check everything but particularly the wiring colours at the various units fed from the CSR, obviously they should match.

HI Andrew,
( UGH ) I forgot to mention this is the 75 XJ12C I am working on right now, I have been on it for awhile, it had the dropped valve seat, the wires I have on this particular harness are :-
2 wires on a common terminal Pink and White
1 wire white and green,
1 wire white and red.
I am sure they go to the main fi relay as there are marks indicating terminals had been recently removed from them. ( that was before I got the car ) UGH ,
Bye for now, Art

doug,your 88 is a beautiful car! i saw it in the galleries page,and art,your cat looks strong,and i hope mine will be as beautiful and strong as both your cars,thank you for all the info

Thanks Andrew, as you have probably guessed I am a grassroots racer type, hey perhaps you can help me with finalizing the 75 V12 Coupe', I just need to know which terminals the three wires from the fuel injection harness attach to on the main fuel injection relay. The previous boys took the harness off before I got to it,
Bye for now................ Art

I wish you well with your S, I have owned my 83 for twenty years and they are very tough, as long as all fluids are kept fresh, esp coolant , transmission oil,rear end needs the posi traction additive adding if the oil is changed in that, and some good 20-50 in the engine, about 12 litres of that good stuff. My car has matured into a weekend warrior for me , but each person has their own road to follow............ There should be plenty of good used parts around most local wrecking yards for the pieces you need......
Bye for now. Come on Summertime..

The V8s swaps were usually done after the V12 was damaged by overheating as a cheap (compared to V12 overhaul) way to keep the car on the road.

Others just don't care to learn how to work on the V12 and want something comfortable and familiar....like a Chevy V8

Cheers
