Hi.

Does anyone know the earthing points for a xj6 x300. 1995 automatic.

I have a few electrical problems and would like to clean up and check the earthing points. Cheers

 

Hi Davey.j,

The earth points are shown in the diagram on pdf page 28 of the Electrical Guide, which you can download here:

Cheers,

Thank you Don. That's a great resource.

Cheers

 

I'm experiencing issues with starting the car.
The car starts fine from cold, however when I try to restart after filling up at the petrol
station it wouldn't start. No crank, no click as if there is no power feeding the starter.

I believe they is a positive battery cable that feeds the starter that attaches to the firewall/bulk head.

If I give this a wiggle I can eventually get it started. The cable is tight on the stud
however the stud spins loose on the body work.

I would like to tighten this up but cannot find how the underneath side of the stud.

Any clues?

 

Don't forget the heavy woven wire ground wire located by the starter . Not easy to get a proper tool on .

 

I'll have at the ground.

I'm just thinking. Maybe the positive cable to the starter that attaches to the firewall is supposed to spin on that stud.... i.e the stud is not meant to be fixed in place ?

Does that make sense to anyone?

 

All studs should be secured and tight including the nut that secures the post through the isolation nylon grommet ( as in a power post ) . You can take the 2 outer wire fixing nuts , torque them together and that will give you something to hold onto as you tighten the post nut . Suggest put some of the " bulb grease " on them located at the counter at the parts store in small packets after you wire brushed and cleaned the area . There is a specific tool to put in a drill for a aircraft quality of ground surface , but a brush should be fine . If you still have problems you may have to get to the other side of the fire wall to address that side of the corroded hardware / wire eyelit .

 

Thanks.

I think I follow what you are saying. The nut that holds the stater power cable on the post is tight.......... am I right in saying I need to tighten the post with a nut each side of the firewall?.......if so, how do I access the post from underneath (do I go trough the scuttle panel?).

Cheers.

 

Yes , But you can use 2 nuts and tighten to each other so you have something to hold onto as you tighten the 3rd post securing nut . If you have to get to the other side of the firewall and clean that up you have to sit in the seat upside down without pulling the panel . I recommend that you do this so you are back to 100 % with that connection . Not a prank . Wiper trough is not an access .

 

Great. That makes perfect sense. I'm I right to access the nut that is on the under side via the scuttle (under the wipers) ?

 

No , see above edited post

 

Wow. Impressed with your knowledge. I take it you've down this before. I look forward to giving it a go.

Upside down should be a laugh.

Many thanks.

 

Davey,

Before you work on any battery power connections be sure to disconnect the negative battery cable at least. I disconnect the positive battery cable too as a reminder to myself not to reconnect the negative cable before I've finished cleaning all the connections.

Also, IMHO dielectric grease or "bulb grease" is good to apply after you have cleaned the ground or battery power connection and reassembled it, but I don't recommend applying it to the terminals, studs and nuts prior to reassembly because it is an insulator and can add resistance to the connection. This is especially important on connectors for sensors and sensitive electronic components.

Cheers,

Don

 

I'm new to this car so I'm learning new things that others have already forgotten . You can address the engine side of the power post for now to get you going and get the inside later for there may be something going on there . In the freezing winter is not the time to maneuver upside down there in some far away parking lot .

 

Cable tigthted and also upon the starter. It now starts on the button.

Next job...... remove the near side front wing.

Has anyone removed a front wing.... any advice.

Cheers

 

English please

 

I was referring to the power cable that supplied the starter. The post has been tightened and the nuts on the starter motor have been nipped up.

I have rust rust on my front near side wing. I would liked to remove the wing so I can repair it.

It it looks like it is bolted on.

Has anyone attempted this job, if so any advice would be greatly appreciated.

Cheers.

 

My right quarter panel ( wing ? ) has a spot of stumble inside where the door closes so I plan on taking the door off . Opening the door half way and supporting it on a jack seems too risky if it were to fall off the jack during removal and bang a corner . So I plan on having 2 ropes hanging from above looped trough the open window frame , angling the ropes forward and aft for more stability . I don't need to remove the quarter panel to get to my area of concern .

 

Lady Penelope,

Davey is using proper Queen's English in referring to the wings (fenders/quarter panels) of his Jaguar. To those of us in the U.S., near side mean's driver's side (U.K. right side), off side means passenger side (U.K. left side). If you would like to know more proper English terminology, see the link in my signature to the list of Jaguar Acronymns, Abbreviations & Terms.

Cheers,

Don

 

No harm intended , just a difference in languages .

Thanks , Parker
