From the HD Dealers meeting, there's usually a presentation like this every year.

thank you sir..............interesting new stuff to read. It won't be long before we will not be able to troubleshoot and repair our own bikes. I do suppose someone in the aftermarket will make the tools available. The BCM and modules in general have been around almost 15 years........about the time HD decided to implement fuel injection.

 

Yeap, there was one in here not to long ago..

 

Interesting, Thank you!

 

I wonder what is going to happen when people try to extend the wires for the switches on the handle bars on the softails which now use a can system with twisted pairs of wires if these are like the ones in a car they must have the same twists per inch and the same resistance in the wires as the original.

 

This is something new to me. Could you explain further?

 

Keithhu - It says the link was moved.

 

Looks like it has. Thought I couldnt see something but if you couldnt see it either, just thats the case.

 

From what I read in the manual they went to a CAN or controller area network setup. More info here http://en.wikipedia.org/wiki/Controller_area_network. The system is very susceptible to changes in resistance and voltage drop. Also uses what is called a twisted pair of wires to carry the signals that must be twisted at the twists per inch as the original or can cause communication errors. I just had a car come to me from the body shop after an accident and the headlights would not work because they repaired a damaged wire and used the wrong gauge wire so the BCM saw a different resistance and thought the CAN-bus was down.

 

Yeah, it does, probably too many people banging on it.
