The only sure way is to buy new ones - they usually have a BS code printed on the side. Otherwise you'll never know if the ones that came off your donor were the original manuafcturer's leads (which should be OK) or some dodgy aftermarket ones.

The SVA inspector will be looking for clear evidence - printed codes - as I doubt that he'll use anything electronic to test.

You haven't been able to buy unsupressed leads for years, the British standard is 1986, if the're fit for use on the car the're suppressed!

Cheers

I've seen leads meant for suppressed end fittings for sale at shows! This is just braided copper.

Anyway, here's what my SVA manual says:

"Check the HT system is fitted with radio interference suppression equipment which complies with the technical requirements of Directive 72/245

As a minimum, evidence of compliance must include the following information clearly and permanently marked on the suppression equipment
- trade name or mark of the manufacturer
- trade description (markings to be at intervals of not more than 120mm in the case of a suppression cable)"

For most people, this means marked cables.

Unsuppressed leads must be available still surely...

I live quite near a main road and the number of those "bloody" annoying little buzzy scooters play hell-up with my telly!

Mind you - it's easy remedied - just shove the wheelie bin in front of em... works wonders! (Jokin'!)
