Am I the Pontius Pilate of this CX500?

Been busy doing other things....like paid work. But I did have one eye on the prize.

ELECTRICS

I've done the whole wiring diagram, but to keep it simple for myself, I've chopped it into easier to digest bits.

IGNITION SYSTEM
Straight out of the 82 CX500 Custom addendum diagram, with mods to to the M-unit.

But first, my great idea of locating the battery box under the rear cowle kissed good bye. Not enough clearance to tyre. When I had the bright idea, the tyre wasn't fitted yet.

Some solder and heat

a bit of heat shrink

battery to starter solenoid

A few more wires and battery box trial fitted under engine.....where it was originally designed for.

111030-191118022148.jpeg


The 3 black wires on the negative terminal go to starter motor mount, to M-unit ground which itself grounds the chassis, and to the reg/rec.

Small step for mankind (not very 21st century)....but big step for this man.
 
On left side of M-unit theres a "start" input from a dedicated control button. Acts as kill switch I believe.
 
Yes. If you hold down the start button with an M-Unit it will kill the engine.

Also, that wire you have leading from the M-Unit Ignition output back to the ignition switch and LOCK input: You're going to want to remove that. Either M-Unit will complain or it will keep you from turning the bike off.
 
For completeness and to prevent others doing similar, I have removed the wire from the LOCK input on the M-unit going to the IGNITION output (dotted line),
and I have added the kill switch (in green oval) to show the input to the M-unit. A button held down will switch off ignition.

Thanks to CXman and Sonreir.

Just a drawing thing, but shouldn't there be a junction dot on the feed to the coils? Also, just to make sure, there should be a good ground for the spark units. When running, probably the most importand ground.
 
pidjones....you are right about the grounding omission ..... The spark units show a green wire which should then go to ground. I did not show that.

Not too sure about the feed junctions thing....straight out of the factory manual wiring diagram.

Ignition and Charging wiring - continued

New connectors to reg/rec soldered on. My soldering is improving - from monumental glubular disaters to acceptable. Pays to practice.

Red to red....and black to black. Simples.

111030-251118000330.jpeg


New connectors for stator wires.

111030-251118000354.jpeg


111030-251118000419.jpeg


These connectors come with a rubber bung that weather seals the back of the connector. These need to go on wire before soldering connector...Doink!

Too late. I don't want to cut yellow cables any shorter, so I'll make a cut in the bung and hook them onto wire, and seal with a little silicone. Trap for not-so-young players.

Piano piano si va lontano..............
 
It's been too hot to do much in the shed, but I couldn't stay away any longer.

I have the ignition and charging systems all hooked up....just waiting on some connectors to arrive to finish hooking up sparkers, coils etc.

To get ready to wire up all the peripheral items, I needed to finalise the locations of all the gadgets, like gauges, senders, etc.

I gutted the old temperature sender, threaded it, and connected a smaller sender that's matched to a digital 52mm temp gauge, which I have tested and verified to work correctly. It's an ebay acquisition, so longevity can not be verified.

I then removed the oil pressure sender, fitted an extension, then one of these large oil pressure senders that is also matched to a digital gauge. I hooked it up on my Suzuki SV650 and it was lighting up and showing some numbers that looked like they could be correct. Again an ebay find.

However, the whole set up looks flimsy, so I decided to make a securing bracket bent out of some 2mm mild steel flat bar.

111030-010119003626.jpeg


And I made sure it did not interfere with the clutch cable.

111030-010119003650.jpeg
 
I then started to make a bracket to retain the two 52mm gauges and a switch for the electric fan switch over-ride. Its 3mm aluminium sheet, which will sit between the clip-ons and the top triple clamp, meaning it will be secure, and my aim is to trim it so you can't see anything but the gauges and switch suspended....so-to-speak. I'm still to settle on their exact location....where they are below, closer together, further apart?

But then it started to boil in my tin shed so I went for a swim (beach is 100m away) and called it a day.
 
Happy New Year, I
I guess it's just past mid-summer in Australia? You'll either have to work nights or shelve it until weather cools down?
I have an uninstalled tin shed to store mover, gets up around 140f in summer time here. Kills batteries real quick.
 
It's smack middle of summer. I actually love to work in the heat inside the shed....but it knocks me about....like you suddenly reach a point when you have to quit right at that moment.
 
Bloody summer. The humidity is the killer up here. Don't mind the heat so much but when you can cut the air it does take it out of you.

Looks good mate. Do you have cups for the gauges?
 
They come with a simple black cylindrical cup which looks ok. Also has a "U" shaped external bracket but I wont need them. Two threaded M5ish studs stick out through bottom of cups and will be used to mount to my bracket underneath.
