How to Repair Relay Control Module (RCM) - (Mystery no Start)
Re: How to Repair Relay Control Module (RCM) - (Mystery no Start)
Here's some photos showing the older A2105400072 RCM against the Crossfire's stock RCM. The only difference I could find was another 15 amp fuse in the older one instead of 20 amp. The car started up fine with the the older RCM. I'll be using it as peace-of-mind for my 1,600 mile road trip coming up soon.

The remote works with the locks and alarm. It will start the car twice but it dies within seconds. After you try starting it twice the the next tries will do nothing. If you unplug the battery for a few minutes you again can start it up twice. Had no issues before this, checked battery all good there, could this be the (RCM) or!!Please help

Have you tried another key? Have you played around under the dash? The halo ring around the ignition key senses the key and if it is disconnected you will have this problem as well.

New Year's Day here in TX. Tried to take my 2007 Sportster (14,000 miles / second car) out last night and it didn't start. I will most likely be attempting this repair myself today.
If anyone wants to send some encouragement my way, or has any tips... Email it my way, or call me at 321. 278.1672. I'm located in Fort Worth, TX.

On the K40 RCM fix, I suggest also using a solder-sucker and first remove the old solder from the 3 lugs, then use a good grade electronics solder to fix it.
( remove the negative battery terminal before diving into the adjacent electronics box )

Sportster ?? Don't know much about Harley's, but if you meant 'Roadster', then basic soldering skills and a magnifying glass should get you there.

You will be able to fix this in no time. Follow the directions and if you don't have a solder sucker, try heating up the point slowly and let the solder melt and add more as needed. I was able to do mine in less than 30 minutes and that was about a year ago.
Good luck and Happy New Year!!

"nothing" from the starter when switched over... or cranks but won't fire off?

Jumping on the RCM without the matching clues is not conducive to solving the problem at all.
Re: How to Repair Relay Control Module (RCM) - (Mystery no Start)
But.. do you by chance hear a single "click"..as in a relay..when switched over to the crank position.. if so bad battery most likely..
These cars don't seem to give you a "slow crank" effect when the battery is down..
RCM does give you a "no response" from the starter.. Also did you check the actual relays on the other side of the board.. burnt or dirty contacts..?

Went to start Crossfire it cranked for one second and that was it . Checked RCM and soldered joints also saw relay points bad filed them. All connectors looked like new.[Thought GREAT I found problem and cured it.] Still same thing. Replaced RCM. Basically what happening is if I disconnect battery for couple minutes after reconnect it will crank for one second maybe twice.on first attemps Then thats it, lights come on but car makes no attempt to engage starter until reconnect battery again. The battery went bad about a week ago so its new and fully charged even tried jumping car. Could it be Crank or Cam position sensor that when engine comes around to it its sending message to shut off starter. Bought obd scanner and will check today car is stuck at work. Thanks
