Thread: 04 XB12R- 64K Electrical Issue

  1. #21
    Ray, I did not get a chance to dig back into it today. I do have 12 volts at the accessory fuse. I took the bottom cap off of the ignition switch - and did not see any corrosion but will have to dig deeper this weekend. I am coming up to a 3 week vacation so lots of time beginning Saturday.

    I will post voltage specifics for the cluster at that time. It sounds like you and I are getting the same readings while testing the VR.

    Thanks again!

    Good info, another quick test is the wiggle test. May help... Also about probing the harness, a set of wire piercing probes. these are the ones I have but any style will work: link to amazon probes

    Thank you for the link and the post-

    This weekend I’m going to wiggle the crap out of that harness.

    I made my own wire piercing leads that I connect to. Easy and efficient.

    Ray,. We're you getting 4.55v on both + & - sides of your vr? I only got that reading on the + side. My - side gave no voltage reading.

    No - only to the +ve DC side as mentioned above.

    "I checked the rectifier/regulator internal readings using diode mode as you have done and I get a very similar reading between each AC input and the +ve DC output - 0.455v one way and open in the reverse direction. I get nothing measuring to the DC -ve."

    Good evening Ray,

    I finally got back to my wiring mess.
    The Mess exposed.jpg
    Instrument Cluster Harness:
    1. pin 2 has 12v w key on
    2 pin 13 0 OHM to negative battery terminal

    Lighting:. Turn signals (fuses are good)
    1. Someone has deleted the front signals by tying the R brown & L Violet wire (see pics) to the return current in the lighting circuit. It was poorly done. I repaired it (assuming it was done correctly. I believe it was if my thinking is correct. Do you suggest I take the violet and brown split connection apart at this point? Since I am not getting power to the RH turn signal switches? I do not get 12v in any of the Violet/Brown turn signal wires.
    Front R:L Blinker Wires.jpg

    I tugged on these and they fell apart- I was hoping that was the issue why no power was present, but not the case.

    I disconnected the cluster from the back of the housing, tested continuity from the front turn harness to the rear harness- across the wires (Violet and BRN) 0 OHM reading which is correct. no breaks. With the key on, turn signals activated, no power to the rear harness (again the front is deleted).

    2. 12v goes to the horn switch. The horn functions correctly.

    3. I tested the turn signal relay and it seems to be functioning correctly although it engages when the key is turned on- I am assuming that is correct.

    4. VR - I have come to realize that the voltage regulator is functioning correctly. I am getting the correct DC current able to charge the battery. The Stator is testing correctly also.

    What it looks like is there is no power getting to the turn signal circuit. Will the turn signals function if the gauges harness is (disconnected or in my case possibly broken)? That might be where the break in the circuit is but I don't know enough to make that call.

    I replaced a headlight ballast and the headlights (hi/low) function correctly. I took the Right Hand Switch housing off of the handle bars and could only find power to the horn circuit in the switch housing with the key on. No other 12v seems to be present in that housing. I activated both sides of the blinkers with no voltage present. SO- back to my question about if the signals will work without the cluster connected.

    I am off work for 3 weeks. I am full time on this project now. I hope I have explained things clearly enough to make sense of where I am at with diagnostics. Tomorrow I am hoping to figure out why there seems to be no power to the turn signal circuit.

    I thank you in advance and sincerely appreciate any further insights you may have. I will be taking the cluster apart to inspect for internal damage. More to come on that.

    Lunatic,

    Sorry for the delay- I purchased a new relay. Decided to test the old one and it seems to be functioning correctly. I posted to Ray on the cluster issue a bit ago. I asked this question in that post, but does the relay engaged immediately with the key activated?

    I am going to take the cluster apart tomorrow. I will post my findings. Do you recommend I purchase a used cluster off of evilBAY as you put it? I think I had mentioned a new one costs 300. I saw a mod posted on here where someone had installed an after market digital cluster. Do you have thoughts or experience with that sort of project?

    Thanks for any insights.

    YES.

    used ebay is fine. it will come with an ebay buyer protection warranty so try it immediately and if not to your satisfaction return it for free. NOTE: the odometer mileage and perhaps even the "face logo" won't be a precise match but ways to address both issues.

    no experience with same BUT for now....stick with stock. you're chasing so many electrical gremlins the last thing you need right now is throwing more variables into the mix. work with what you have.

    Great advice regarding the cluster. Will do as you suggest. Thank you.

    Ray and Lunatic,

    I disassembled the instrument cluster, cleaned the circuit board, cleaned the harness connections and plugged it back in. To my surprise, it cycled and all the lights came on. Good news. I am reinstalling it now, and hoping that it helps out the turn signal concern. I still do not know if the turn signals will work without the instrument cluster plugged in.

    Had to share the good news. More to come.https://www.facebook.com/tim.jacobso...type=3&theater

    Flasher- 12v Or:W.jpg

    Back Side of Flasher Switch.jpg

    I tested continuity as Ray suggested from the switch posts to each location at the cluster, to the tail harness where the lights plug in. I wanted to make sure that each harness connection was functioning (hoping to locate a bad harness connection). Every wire tested as it should have. I am assuming this is good news and possible means that I have a bad flasher. That said, I have tested the flasher and it functions correctly. I have good ground to battery back at the rear harness. I just have no current getting to the tail section. I am not sure what I am missing in all of this.
