[QUOTE="Queensland Ken, post: 1336551, member: 4399"] Try and keep the many neutral paths intact, the bypass is only a bypass, you would have to work out the possible neutral current loading and work out the appropriate AWG size as used in automotive wiring. The larger the diameter, the higher current it should draw off the the original single path circuit. It is NOT EARTH it is a neutral circuit back to the battery, no difference between active and neutral technically speaking. As in most electrical installations, there is only one point where neutral and earth are bonded, the one place under the RHS header pipe. This ties 12V neutral to earth, only 1 point. That is also good to treat with carbon grease. In 240 volt installations, really weird and dangerous faults will happen, a shock from 240 V neutral is far worse then an active. If you have multiple bonding points funny things may happen in low voltage electronics, electrolysis, buzzing through the headsets, accessories, maybe even ECU faults. I could provide he right size after a bit of research, have most of the figures. Just treat the S6 connector, solder the spider bridge and run at least a separate 2.5 mm wire CSA to the battery -VE, not the frame. If you cut the connector off, still solder in that additional bypass to the battery, if you solder the wiring bundle. Good you checked the battery connection of the recall. Mind you the 2 spiders under the headlights are somewhat bothersome as well. Try and at treat all the connections one rainy day. [/QUOTE]
