So not sure if you all remember but my PDM/HCI took a crap. Waiting on my RIP to come in I have been going through the bike and cleaning/fixing a few things. My TACH ring also stopped working (High Beam Indicator) so took the time to take the cluster apart and clean fix it.
Well got it all back together and the speedometer is now not powering up. I did not drop or bang it. I took the original clear heat shrink off the braided cable to redo it. WTF? I was able to remove the sealing connector and I did not see any broken wires. I am thinking of taking it apart and checking. I saw a post about taking theirs apart, is it a pain? IS there anybody out there that can repair these things? I really don't want to replace it.

I'm not sure about those components needing a 'highway,' but describe the shrink removal, plus the highway part is called CANCOM, where a wire is wrapped with so many winds around the other wires. Did you unravel one certain wire that looked like it wrapped around the others?

Controlled Area Network Communications means, I have to make a path to the meter from the ECU. The wire wrap is where hi and lo frequencies intermix. One has to make a path so they do not cause a frequency clash with each other. So a CAN bus address is transmitted to two nodes-the ECU and meter. Unwind that wiring, there are certain twist counts, how tight or loose they may be, such mods to those leads can cause communication errors.

WATT was the last thing I did to the bike, and in this case was this heat shrink removal. Do I think a wire becoming loose is the cause; and here I am just describing how 'some' wire harnesses are wrapped for this computer type of bike. This bike being not a BD, but if there are lots of sensors involved, CANCOM sort of bleeds out the loom, if not in the loom.

So the question is... did we find a certain wind of wire(s) that circled the other wires, and how many winds were untwisted if any? This is one off the wall variable, me in the black box study and its relatives in speaking terms.

WTH are you smoking.......


This is not a high tech com bus. It is 3 wires. It is +12V power, Ground and a signal wire. Not sure where you read highway but the pig tail has a 3 wire bundled cable with a stainless braid and a clear heat shrink over it. I took the clear shrink off and put new pretty shrink on. All wires back where they belong in the connector.

The first sentence I covered my ass sort of not knowing the product. I assumed main harness tampering. I'm also assuming fuel injected. Carb, no so much telemetry needing CAN. Either way, I play the generic, walk up to the bike, I better know a few things going in I start messing with a computer bike.

No power to the speedo, but it worked before the cleanup.
1. Red to control module and speedo sensor. Plug #5 using a 2007 wiring diagram. Check power at the speedo sensor's harness side that holds the ground connector [with the red] wire.
2. Black wire would show a ground from its pin in its own connector to ground - ohm the connector side to the frame and see if it's broken going to ground? Ground the speedo ground wire to the case and see if it completes a circuit.
3. Green to the speedo sensor. See if green wire has integrity up to the speedo sensor plug end of that harness connector side, not the sensor side connector... assuming the sensors are good.

I just took my speedo appart to weatherproof it when I installed my ESC, but when I removed the tach ring I accidentally scratched the circuit board and I lost my 2000 rpm light! You really got to be careful when removing and replacing that circuit board, the metal ring that holds it in is kinda hard to get in place without it touching anything on the circuit board and shorting something out, maybe something is shorting out in there, I would take it apart and check everything out again!

Franco, are you asking me for the size of the risers? Or the pitbull handlebars? I am confused. The risers are 1.25 diameter 2" in length.

I just need to know the size of both... I will look now at the size of the handlebars on my K9. Its just to make sure I order the correct size.

BTW, I have not PM you yet regarding Rota, I will shortly. Nothing major, its just a favor I´d like to ask from you. :oldthumbsup:
