S above can some one please point me in the direction of the lication of these please

Not 100% sure on seat but most car manufacturers factory manuals have a page or two showing the location/layout of all the earthing points on the car.
 
Did a google search last bight and it didnt throw any rhing up...will have a look in the books i got with car but dont remember seeing anything like that before

Found this, link below , but sadly it only shows the engine compartment earthing, but it does mean that the earthing points are shown in the seat factory manuals in detail , maybe someone on here has a manual and could pdf you the relevant pages or you could probably find a copy on fleabay

Thats all for mk1 leon not mk2...that the issue i had loads comes up for mk1 cant find sqat for mk2

My mistake, was searching on my smart phone,thought it was for the mk2.

I've just remembered, you can now access the genuine seat manuals online, someone posted a link on this forum a month or so back, you pay a small fee to view then and print/ download what you want, I'll see if I can find the link for you
 
Yea ive tried that page on the link before cant find any diagrams on it tbh will try the other... i did manage to find 5 earths ( dunno is theres more tho) 2 major ones from battery and alternator/starter and 3 snaller ones... cleaned them and my demister seems to behaving but lights still flick on switches

Yes there are more than that , There's quite a few scattered around inside the car, when I've had strange electric problems though its normally the main ones from battery negative to body that has caused the issues and it's been that the cable/wire strands have broken down inside the cable as opposed to the terminal ends not making good contact.
Never really had an issue with the Earth's inside the car passenger compartment, unless the car has got wet inside at some point in its life or someone has badly added extra earth's for amps/subs ect to the existing earth points or someone has butchered the cars loom adding alarms/trackers/stereos etc
 
Well update is i have test the resistance of the negative battery cable and done a voltage drop test both of which show the cable is fine....gues i need to look under dash now at the earths there
