Puffs,
I am not claiming this wiring upgrade is my own original idea. I probably read about it in the MZ club magazine during the 1980s. At that time complaints about invisible indicators were probably second only to debates about the useless front brake. I remember checking for voltage drop between the battery and ignition switch and finding a significant amount with the original wiring under full load. It was this which motivated me to upgrade the relevant wires rather than heat or damage. The loss was eliminated with the heavier gauge wires, which I have used ever since with 6V MZs.
I've never had your problem with the wires cracking, so not convinced this is an issue with the MZ - perhaps you were just unlucky on one occasion.
As it happens, I rarely ride with daytime headlights, so my indicators might not be limited by the standard wires anyway, and if people are happy with their 6V electrics there is no reason to change. But if not, it is a cheap and easy mod which might make the difference, or if like the OP you are starting from scratch.
