Thanks, again for the responses.

A fewthings:
1) I am using the data connector behind the right side cover, right beside the ECM,
2)I'm not liking Vista very much either,
3) Tried the voltmeter test, and I was able to measure volts, but it was on Pin 3 (-10.15 vdc).

 

fireman403,

Got a few questions now that we've gone this far:

1. What is the model number for the Belkin adapter? Not all of them support Vista.
2. Its very encouraging that the Device manager detects the presence of the adapter. What COM port does it show up as?
3. Its also encouraging that you did see the negative voltage (-10.15Vdc) on a pin. I'm suprised that its pin 3, that means that pin 3 is the transmit pin for the adapter and pin 2 is receive. The cable from the SERT that plugs into the adapter has 9 "holes" that match the pins on the Belkin. If you hold the connector with the row of 5 "holes" on top they are numbered 1 through 5 starting with 1 in the top right hand position. This is a mirror image of the pins on the Belkin. Anyway, if you measure for voltage again on position 2 and 3 (with ground being position 5) you can locate which position is the transmit (it will have the negative voltage). You will need to do the usual steps for readng the EFI module, ignition on, kill switch to run. You want to try measuring the cable to see if the SERT is trying to transmit on position 3. If it is, then when you plug the SERT into the Belkin adapter you have both devices trying to transmit on the same pin, which won't work.

For the Belkin to communicate with the SERT the transmit on the Belkin (pin 3) must connect to the receive pin of the SERT (which is hopefully pin 3). Transmit for the SERT is hopefully pin 2, which connects to the receive pin of the Belkin (pin 2). We know that pin 3 of the Belkin is the transmit from the negative voltage you measured at pin 3. There was no voltage seen at pin 2, which is correct - the receive pin does not have a measureable voltage since it is listening, not sending. Now if we can verify which pin on the SERT the transmit voltage is on we will know for sure if the adapter is compatible with the pinout of the SERT. It is possible that both the SERT and Belkin are trying to use the same pin (3) to transmit, which won't work.

 

Update on the SERT troubles:
I measured volts on Pin 2 from the SERT, but itwas only -5.25Vdc ??!!

But, the bigger news is that I had opportunity to drop by the Harley shop today, so I carried my SERT and the cables to have it all checked out. They offered to plug it all together and give it a try (for free, at that). I purposely did NOT tell the technician what it was doing wrong other than it just didn't work. Surprisingly, he came back and said their Digital Technician wouldn't even connect to my bike. It displayed a message similar to what I was getting, "ALDL adaptor...not responding".Since Ihad already checked most of the connectors before all this trouble,I'm starting to think the ECM has got some sort of 'brain damage' (although the bike runs fine as is).

Thanks to all for the help.

 

The SERT key might be at faulty.......it's what opens the line of communication with the ECM, just a thought

 

The dealer toldme that he first triedconnecting thru the SERT and when that didn't work, he tried connecting directly to the Harley Digital Technician. Either way, he couldn't establish communication with the bike.

 

I had a sert ,half way through the download it crashed...after that it would not connect to my bike. took it to a dealer and they couldnt do anything..the thing is fried, they said it was a faulty sert. The thing is harley wont warranty it, when you take it from the box and break the seal it is non returnable!!!!! how the f*^ÂŁ@ are you to know that it is not faulty without taking it from the box?????

 

I just did a Goggle of "harley Davidson warranty", it's not very encouraging. [&o]

I would like to see in writing there warranty on new parts sold. I suspect the warranties are unwritten and left up to the dealer to decide.

 

Well, I think I'm going to give up on the SERT.

Although the dealer suggested a wiring issue with the data link plug on my bike, I can't find a problem. I followed the wiring diagram from the service manual and verified continuity for all three pins on the plug and at several different points, so I don't think that's the problem. I've even tried a 'reset' of the ECM by pulling its fuse. The SERT just won't connect.

Thanks again for all the suggestions. I know I'm just frustrated right now having spent so much money on pipes and a tuner, but I almost want to return the Rineharts and get at least some of my money back.

 

I read a forum somewhere that said there was problems with some 2008 ECM's and that one dealer had to trade ecm's from another new bike to make a sert work!

 

The problem with the ECM's was related to the new ProTuner....it won't talk to the ECM unless it's # ended with a 'A'.......the new Pro Tuner must have been built in Canada.....
