What to do with surplus zener diode wires

I have installed a Podtronics regulator/ rectifier in my Commando - single phase 2 wire Alternator - now that the zener diode has been eliminated do I simply leave the wires disconnected ? I can connect the red ( ground / earth) to the chassis but do I simply leave the brown / blue supply disconected ?
( making certain the end is insulated/ not shorting) The instructions for the Podtronics unit explain the connections for the new unit and there is no reference to the now unused Zener wiring. This is a new main harness BTW-
Also , the warnings about shunt devices and their potential for damaging the alternator windings have been considered and I have chosen to take my chances.
Thanks in advance from an electrically challenged individual.
Cheers- RT

I would connect the red to the chassis ..... no harm in that, and more earth connections is insurance.

Next, I would insulate the connector of the unused Zener wire, and tuck it into the harness so it is there for someone who might want to go back to original.

Slick

Agreed. Don't throw the baby out with the bath water.

I heat shrink and pinch every wire end I do not use, then wrap with a bit of silicone tape and secure to harness.

I'm making a Christmas tree ornament out of my unused diode parts.

Thanks Gents - just what I assumed ( guessed ? )

this is probably much to do about nothing, but I ran the wires (Zener power and ground) as normal - terminated the ground to the rear bolt on the foot peg mount. I had a old, spare, Zener - applied a piece of shrink tubing over the electrical tab and mounted it in the support plate with the tab facing downward. I installed another piece of shrink over the harness connector and secured the lead to the frame with a zip tie. this way, there is no way that the zener could be connected by accident. I did this to not have an open hole in the support plate and to maintain an overall stock appearance.

Mine is negative earth now, with a 210 watt 3 phase alternator. The zener will never be used again. Wires taped up as advised here. The hole is filled with a chrome bolt.
