![]() The way I see it...... Ash,s IVA test was a "High profile" one, being in the magazine etc & maybe the tester went over his car with an EXTRA fine toothed comb etc etc, I,ve heard of cars passing the test with the brake T piece just rivnutted in place so its open to the tester,s opinion I believe ![]() As the earthing points are merely just attaching a wire to the chassis I presume its classed as a non critical securing method , basically if the nut came off it wouldn,t allow a major safety component to "fall off"..... Thats the way I see it, rightly or wrongly I,m not sure ![]() ![]() I remember one of Ash,s quotes...." use a Nyloc in a place that if it fell off would it kill me "... cheers andy |

![]() My logic comes from my my days playing with race cars and dealing with scruiteneers. The basic rule that we worked to was any fastener that could affect the operation of the car must have a positive and clearly visible locking method - i.e loctite was not acceptable as you couldn't prove it was there. So we used Nylocks, K-nuts, lockwiring etc.
I may also be paranoid as a mate who races dropped out of a race a few weeks ago when the plain nut on his earth stud come loose and the car died. Similarly I wouldn't want to be in the outside lane of the motorway when the engine cut out due to a loose earth!

![]() My one concern over using rivnuts for earth points is electrolytic corrosion taking place and causing poor earth connections in the future. Basically if water and or road salt got into the joint between rivnut and chassis it could cause corrosion due to the zinc or nickel plating, classic dissimilar metals and moisture giving rise to the corrosion. If its on the joint between chassis and rivnut it could be very difficult to find and cure. Just a thought.

![]() A smear of copper grease on the rivnut should protect it.

![]() Fair point Adrian, is copper grease conductive though? I've never tested it

![]() I doubt the IVA would care about nylocs on electrical earths. You don't find it on production cars, some have spade connectors for earth terminals.
I have never seen a nyloc on a battery and that is the EARTH. TT
