I added a close up of the m.unit after realizing that you can’t really read anything once you zoom in. Hope this helps clarify things. I will be adding the stand switch and possibly the bank angle sensor.

You wouldn't believe how packed in everything is on these bikes. My dad's bike had the thermostat hose slip off of outlet. MAJOR surgery to get at it. Replacing the crank would have been less work. Putting all that plastic back on felt like leaving a foreign country. I will never see this again in my lifetime.

Same here. Dreading the possible need to clean, it’s bad enough I will be rejettiing it due to loss of vacuum nest.

This is appropriately stated.

In other news, I have been whittling away at the wiring harness.
1/2-1/3 of the wires removed from the main harness.

I am probably going to reuse the wiring and just use solder seal butt connectors to get extensions put in until I get home to AL and have a proper space to work on this type of project. I am going to order new terminals from www.cycleterminal.com and have them waiting for me. I have been sitting/laying on the floor of my room and it’s killing my back. :(

I still haven’t figured out how to tie in the bank angle sensor maybe once I get the system powered on I can figure out how to tie it in appropriately.

Rewire is coming along, I have to plug the windows on both master cylinders which then led me to checking my clutch slave cylinder.

To get access to clean out that area I had to drop my headers which led me to some rust busting and cutting away the mounts/heat guards. Sorry I forgot to grab a before pic.

Once I got that sorted I was able to clean up the slave cylinder port while I wait for new seals to come in.

Carved up the OEM seat so I could reuse the seat pan.

Planning to carve up the air box to switch to air pods, I got in contact with BobManifold and that is how he got around the stock air box. I will try to document that as much as possible when I get there. Other than that I am currently routing wires before I clean up the harness for wrap, I am trying to reuse connectors where I can.

One question I have that maybe someone on here smarter than me can help with is where to draw power for the alternator? I’m not sure if I should feed power from the starter solenoid through that 30A fuse or from a 10A-20A protected circuit off the m.unit Aux 1 or 2, respectively. I have an updated and revised wire diagram but it’s not coming through on the upload so PM if you would like to see my plan and I can send you a high res diagram

I guess my first question would be When does the alternator tie in on the stock application? The diagram on the previous page shows it connected to the battery output without a switching unit. Is that normal?

The OEM configuration ties power in, from the way I read it, when you turn the key. Key turn pulls battery to a 15A fuse. That pushes power out Bank Angle Sensor AND splices off to a relay that sends power down another line to the Bank Angle Sensor as well as the alternator... along with everything else that requires power to start via other relays and fuses.

I found a work around to post a look at them diagram.

It’s taking shape. Wish I could help with electrical.

Yea that sounds better. It needs to be switched power I would think.

So then from the m.unit, go with 10A or 20A?

This is a feedback signal (sense signal) or the starter output?

Chip, I rebuilt the clutch slave on my '91. It was one of the more difficult jobs I've done, mostly because it's hard to get your eyes and your hand on it at the same time, especially while you're on your back!

This is where my BAS should be.

I am confused by your question. I am going to connect the alternator input to the Aux 2 ports giving a 10A fused link unless I discover that it needs more than 10A to do its job.

Getting it out was tight, I have since dropped my exhaust giving me loads of room to play and see.

Yeah I have seen a lot of jump these two wire to eliminate the BAS, I was trying to figure out a way to loop it in.

As I write this I think I might be able to tie it into the ignition line and when the bike falls over it could ground out, or fault, that output cutting power to it and essentially the ECU. Does this make sense to anyone else? Once the bike is stood back up it would correct the fault and you could restart the system.

Most alternators with an internal regulator have a output wire and a feedback or sense wire. It tells the alternator when to reduce output as the battery is fully charged and maintains a target output of say 14.5 VDC So like after cranking to start and the battery is down low the alternator will put out max power to get the battery back up. As the charge in the battery increases the demand goes down. The feedback/sense provides that information to the alternator so it does not cook the battery. I have no idea if the 1500 alternator has an internal regulator or if it is a separate component?? The sense wire should be low amperage. The output wire and associated fuse I would want just above the rated output of the alternator. So if the alt is rated for 40 amps I would go with wiring and fuse for 50.
