State of affairs come August

After struggling with the electrical for about 6 weeks I gave up and dropped the bike at RPM Attack in Glendale. That was on April 15th. The bike has now been at this shop for 3 months for the turn signal fix. I am a bit fed up and have told Chris at RPM Attack that I will be picking up the bike this Wednesday done or not or whatever. He seems like a nice guy and the work that he's done thus far is decent but he's told me "the bike will be done by this weekend" for about 9 weeks in a row and I'm over it. 

The bike will be coming home this week. After which it will be time to do the following:

  1. Assess how much progress Chris made and try to get the signals working if they are not already.
  2. Add spacers and pegs to come off the luggage brackets. 
  3. Replace the kickstand with one that is not bent.  

 

Electrical hell cont'd

I struggled for ages with the electrical and made all these charts. Please contact me through the site if you'd like me to send you any of these wiring diagrams I made with the overlays. I isolated most systems.

electrical hell

I'm posting this retroactively but I struggled with the electrical from January to March this winter/spring of 2018.

The harness was way too blasted to be used and I replaced it with a new one from Bikerpartsuperstore.com It's a good piece of gear but I had some issues.

The FXR's were made with all kinds of different configurations and the harness will have to be modified to suit the ignition, dash and key/switch layout of this bike. 

I would very much like for the original turn signal cancellers to work. My first bike had these and I loved them. It was super intuitive to signal left with left thumb and right with right thumb and I loved that they self-cancelled.

12/04/17- Electrical

I've spent the past week sorting through electrical issues. I had been pressure washing the bike between intake and pipe installations. I was doing this to gradually get all the crappy rattle can paint off the engine but I think I shorted something as my ignition stopped getting spark.

I'm running an Ultima ignition with what I believe to be a single fire coil. This is good because it's simple and supposedly pretty stable and high quality. I have discovered, however, that I am missing the Vacuum Operated Electrical Switch which is supposed to advance the timing at higher RPM's. Will think about adding later but for right now will try to get bike back on road. The Ignition wire sleeving was eaten through by some of the solvent I was using to peel the paint. This is frustrating.

The wiring on the bike currently is a bit of a joke. Lots of things missing including the ECM, turn signal canceler, and others. The front of the harness by the controls has a bunch of quick splice connectors and the whole thing is covered in heat shrink and huge soldering bumps. Against the advice of Jackson at Lucky Wheels I have decided to gut the harness and replace with new rather than chase down the spark problem. This will involve the following:

  1. Take out old main harness and re-run new.
  2. Add turn signal canceler. 
  3. Re-sleeve Ultima Ignition Harness and test voltage and continuity. 
  4. Build/repair control/switch harnesses with Multi-lock connectors. Research has led me to Namz as the only supplier for the original connectors for Harley 1971-1995 are called "Mate-n-lock" and I can't find them anywhere else. The good news is they are relatively easier to deal with and cheaper than Deutsch or later Molex. 
  5. Re-adjust ignition timing. 
  6. Fire up and ride into sunset???
