As this is just a semi temp install maybe for 6 months.
I really dont want to pull the extremely tight fitting trim apart.
I have found 2 easy to get to areas.
1. Is a bolt , that is holding the centre console down under the cupholder compartment.
2. Is behind the rear centre armrest.
They both seem to bolt into what looks like aluminium / magnesium alloy.
Q.1. Are these alloys good enough earth points? (note there is not much steel on this car eg front wings, bonnet, boot, doors, rear sub frame, floor and front subframe and roof are all some kind of magnesium/ally alloy or straight aluminium
Q2 if I run a cable from the negative battery post to a given selected part and there is very little resistance on a multimeter is that safe to assume thats an OK earth point, for my new USB charger point powered by the cigar lighter circuit?
