400/4 build. Paused due to other commitments. But starting up again
ComfySofa:
Yeah - i think thats where im at...(the whole spaghetti thing) but, another aspect of this is the learning curve....never been good with electrics and thought this would be a good way to learn....i have used an munit before (the older type) and while a mate fitted it all - i will say that with regards to the mbutton and the switch gear (im using all oem this time) i did feel that the wiring was very flimsy and thin (dunno what roo thinks as hes using all that stuff i think) but - the downside is that using the oem switchgear presents its own set of problems as its more custom (getting it all connected and working like it used to)
Left to my own devices yesterday as i said before somethings have started to click and i can start to see, the simplicity of the way the MUnit works...
K2-K6:
There's basic difference in concept between the two, discussion may help understanding.
Original would route power to a bulb, for example, by going from battery supply, through the bar switch , then to the bulb. open/close the switch and you cut/connect that route. So very simple on/off status.
M unit, has route from battery supply, through solid state switch (inside M unit) then onward to bulb. That solid state switch interrupts the supply, but its "called" by the remote handlebar switch to ask it to go on/off, hence the bar switch needs only to handle a signal voltage and not full load. Which is why those operating wires are small.
It's effectively all a relay system, the M unit, with power handled by the primary wires, then an overlay of command switching telling the unit what you want it to do with light duty signal system.
Both are reliable if all built properly and connected well. No particular advantage either way as the whole system is not actually controlling much on these bikes.
K2-K6:
It maybe "stating the bleedin obvious" (faulty towers reference) but both system requires competent earthing to all components exactly the same, else neither will work properly :)
ComfySofa:
This is true but one loom is 40+ years old and the other one is brand new...

Just wot K2K6 wrote ;D
Heaps tidier and a lot less space consuming and of course all the other benefits of alarm. keyless ignition, tracker, position finder, diagnostic screen for problem solving, 'draw down' real time scematic showing individual draw in voltage for each circuit and trouble shooting auto settings so that if there's an issuewith a circuit it will close and re route to get you home showing clear indication as to where the fault lies and what circuit has the error. It is a really good system if you have no loom to start with or components mssing or even fancy having a go or indeed have made up all the items in your loom, its a really realy good application.
Once all the info is in it will track your milage, advise of milage related service intervals tyre reminders, etc. theres lpads of features i cant remember either but its worth a read.
Ted, watch REVIVAL CYCLES TECH TALK on 'wiring your motorcycle' and ' wiring your revival cycles starter solenoid' (dont buy one from them there 48 quid..........18 over here in the UK.
The wiring kit is dead simple also with every wire printed on it with where it goes and colour coded such as INPUT R IND, OUTPUT R IND, START, HORN etc etc. easy to follow......have a read wiv a brew Ted 8)
