1990 1.9 DG Waterboxer replacement rotor arm shorted out?

[SWTurbo]

Fitted a new rotor arm and distributor cap to a 1.9 DG, few miles down the road it broke down and a recovery company said the new rotor arm was faulty and shorted out. Any thing that could cause the rotor arm to short out outside of it being a poor quality arm?

What brand and parts supplier? Rotor arms have a resistor in them, they can fail although I have yet to experience that.

and there is the rev limited version with the centrifugal contactor so parts id is important

Part was from heritage parts centre, 071-905-225/A, its the 5400 limited one.

Many moons ago l was advised not to use a limiter rotor. So didnt and never had a rotor short out problem. But can't recall the reason?

Try a standard version rotor and report back your findings.

very few peeps will ever rev a wbx to 5000rpm, even downhill when late for a booked ferry
use the DJ one 055 905 225 B

It's something you don't need and an extra thing to go wrong

how can it be shorted out. 

The short path is from the center to the tip, where else can it short to?

It could likely short to earth ie to the end of the distributor shaft.
