Hi all, I have a major headache with the wiring on my Yammy 02 WR426f and as a last resort i'm having to ask my fellow thumpers for the answers to my problems? before i go into it, let me just say that i have searched all over these forums and although i have found some very useful info, i can't find the solution that matches my exact same bike or question. there are so many different opinions that after several hours reading i am now totally confused as to what i have to do to sort my bikes wiring. let me explain: as mentioned above i have an 02 WR426f (european) that has H/L headlights,tail/brake light/horn/neutral switch and indicators that come as std fitment on most European WR's i think? All these run on AC power from the stator into an after-market handlebar switch that has ALL buttons to work them, also has a combined kill-switch too. everything works as they should without any fuss, but here's the big dilemna.......... I want to add a Battery so i would no longer have to worry about the indicators/horn not functioning properly when idling etc, the headlight/brake and tail are ok but obviously they dip at idle too. i only use my street-tard on the road and i really would like to have proper functioning electrics and to do this i need to have a battery. I managed to get hold of a battery and wiring loom (harness) plus the reg/rectifier from an 03 WR450, and also a cd rom version of the 03 WR manual. Innitially i thought i'd just replace my loom with the 03 one, but changed my mind as there are many more connectors than i thought there'd be and most of the wires are different colours and far too many excess wires/connectors than what i'd need. so i decided to somehow add the battery into my current setup that would give me AC/DC for the headlight/tail & brake and DC for indicators/horn/fans etc. plus the ability to have working lights with the engine off 9which would eventually be wired into a keyed ignition/isolator switch. Now here's the problem? My AC output from the stator only has ONE wire (yellow) plus the 6 wired plug (CDI) but the 03's reg/rectifier has 4 connections, which i have come to understand is 2 into the reg/rect and 2 out to the + and - on the battery. there's my problem! where do i get this other wire from? will i have to mod the stator (float the ground) that i've heard so many people on here mention but NO actual references explaining exactly if it HAS to be done or HOW to actually do it. most of the talk referred to older WR400's or converting to road YZ's as they have very little or no Wattage from the Stators etc. As i said before, my lights and everything are ok when riding, even in the dark the lights are well sufficient, it's just when on tickover they're poor and the horn sounds like a dying fly and the indicators barely light, let alone blink! so, onto my questions (hopefully you've made it this far) 1: do i need to mod the stator to achieve AC/DC lights with DC indicators/horn etc given my current wiring setup? 2: what about the earths, should they all go to the battery apart from CDI/Coil? 3: would it be better to go for all DC lights/horn/indicators etc or would this be too much of a drain on the battery as i always ride with lights on during the day? 4: how would this affect the CDI if i went allout DC or would it not affect it? 5: if i floated the earth (from the stator) would that not stop the coil from working, as it earths on the frame or would i still need to have an earthed frame? as you can probably tell, i am in quite a dilemna over this and i am at my wits end. I am ok at electrics as long as i have some sort of wiring diagram etc but neither the 02 or 03 manuals bear any relevant info apart from the 03 stator wiring diagram shows 2 wires coming out of it unlike the 02 which has only 1.... hence my questions.. I hope you guys can make sense of all this and what it is i am trying to do. I have researched and then some from the likes of Baja designs, trailtech etc etc but i am very confused and was hoping there's somebody out there who has added a battery to their 02 WR426 that has the exact same wiring loom as mine? here's hoping........... thanks for reading anyway, lol.. "Electric Start" ????? what a luxury that'd be?! i shouldn't be greedy i guess, i can start mine wearing me trainers!
