For those with IAC problems, did your speedometer quit? First thing I noticed was no speedo or odometer and then bike shut down when I pulled in clutch to pull over. I am leaning toward an electrical problem...

 

I never had any other visible problems. I would just pull the clutch in coming to a stop sign or a light and the bike would stall. Press Start and it started right up. Sometimes it happened once a day sometimes it happened multiple times a day. It was very erratic but I changed the IAC and then reset it. It's been years now and I never had the problem again... still have my 06.

 

Did you remove the cap on the relay and inspect it internally? Many times the corrosion goes past the plastic base and into the relay components.
Similarly did you inspect the socket and wires that were plugged into that corroded relay? Many times those are just as corroded.

 

 

I just got the new relay to replace the corroded one. I will report back on my progress. Sadly being an intermittent problem it could take a while to see if the bike is truly fixed. So far I have checked connections, cleaned a corroded relay, and replaced speedometer sensor. New relay to be installed. Sounds like ignition, IAC, and kill switch are on the list of possibles. So glad that some of you found your problem. I suppose I could take it to the HD dealer but without really knowing the cause they would likely start replacing stuff same as me.

 

Yea unless you found the right combination of conditions to actually have act up repeatedly.
Most mechanic's I've known will tell you if the problem can be duplicated it goes a long long ways to finding out what it is.

Good luck WP

 

I posted below on another forum before I joined this one. It is kinda long if you want to skip over. It tells my whole story about this problem

HDs connections were never coated with silver.. Some are coated with tin..

It's not the resistance property of silver that makes it useful but it's anti corrosive properties. Gold is better.

Nothing wrong with brass contacts.. They can be cleaned up. What helps connector contacts to connect electrically is simply unplugging and plugging. The wiping action make the contact.


AT the OP,,
Do you have a TSSM? On this year, the TSSM can disable the ECU by sending a message to shutdown the ECU. Also TCMs and TSSM have the tip function. Not sure if the system records security issues but it will record tip..

I own a 07 FLHTC. It had an issue where it would shut down when really cold, pull over to the side of the road, cycle the ignition or run/stop switch and it would startback up and run. It didn't do it very often but maybe once every couple years. Last time it did it, I switched the ignition off and toggled the run/stop switch a bunch of times.. It hasn't done it since.. Not sure it's your issue but the issue was getting more common (at normal temps) and after I toggle the switch a bunch, it's stopped.

 

@kemdds Reading this and your other forum thread the corrosion seen on the relay certainly needed to be addressed.
My thinking is it was a real possibility of being the problem.
A couple of questions
1 Have you identified the relay that you cleaned up
2 Did you do what foxtrapper suggested ? Did you get the Amazon relay installed.

Silver coated starter solenoid contacts make helped them last 100K. After marker copper ones were lucky to go 20K amd brass if you were lucky didn't weld together and keep cranking a running motor. Now that's cars.

Silver has the highest electrical and thermal conductivity of any metal, along with having the lowest contact resistance. (Google)

What Harley first had not sure of. They didn't put starters in them in the 60s I guess. So guess your right about no silver on contacts. Sure Harleys only used the gold on bling. I bet his fuse box connections are a pitted mess.
