Getting a lot more beep-bop-boop this time.
On order we’ve got an m.unit blue, 2x m.switch three-button controls, and a motoscope tiny speedometre (all Motogadget products). I’m re-doing and simplifying the entire wire harness and getting rid of anything I don’t need by going to the m.unit blue. Only other change to the stock bike is the previous owner installed an electronic ignition (back in the 1990s). I believe the stock regulator, rectifier, and diode board is still intact, just the points system is gone.
My DRAFT DON’T USE THIS YET wiring diagram (click to enlarge):
Questions (note this applies to the new m.unit blue, not the older m.unit versions):
- My main concern is connection to the ignition system, starter, and the generator areas (i.e. alternator / regulator / rectifier).
- No fuse needed between battery and starter solenoid?
- Best practices for running ground up to the front of the bike—I’m thinking a dedicated wire and clamp harness that all front controls can ground to (instead of individually grounding).
- Can the speedometre sensor (mounted near wheel magnet) send a signal to both the speedometre AND the m.unit at the same time? As I understand it the m/unit can then record speed data, correct?
- Can I use both a key ignition switch AND the bluetooth smartphone unlock to unlock the bike? Or will there be some sort of conflict?
- My turn signals are incandescent bulbs, not LED…do I still need a diode between their signal and the speedometre LED lights (i.e. so I don’t get bleed from a right turn signal bulbs turning on the left turn signal bulbs?)
- I’m wiring my handlebar clutch lever switch to the new “STAND” input on the m.unit, i.e. bike won’t start until clutch lever is pulled in (it’s a safety feature I think is worth it). Are bump starts still possible with this set-up though?
