Can anyone explain how ya check ya ECM, Im Getting no spark to my coil, I've checked my coil,leads and spark plugs to another bike and there fine.

I Have a 2005 ultra glide, if that helps.

Cheers Finny

 Well i tried a new computer and that didnt work, I cant understand why i have no spark.

Ok So i did some head work, Put in a set of cams took it for a spin and found there was no oil getting up to the heads, Pull it back down to find i 

had the lifters ass about, Put it back together , go to start it and it wont turn over, I have no spark , I have taken all my gear (coil,leads,plugs, relays)

and tested them on another bike, All fine, then i thought it might be the ECM, But no tried another 1 of them and still nothing. I have stripped down 

the wires to see if 1 of them was split or broken but could not find a bloody thing. Mutherfuckincuntwhoremoleslut of a thing. So its on the trailer to

go to a Auto Elecs, to see if he can find a problem, If not im buying a bag of Marshmellows.

fuse? is the ecu getting power? coil getting power?

Check the TSM and make sure its not tilted. Can you hear the fuel pump priming ? No pressure no spark. Check all the earth wires from the battery frame, gearbox etc. Make sure the battery is good under load.

The auto elec rang and said there's pulse going into the computer but no pulse coming out ?

He has gone through all the wiring harness from computer to the coil and can't find a fault ?

Its got him even Baffled,

TSM Turn signal module has a bank angle sensor that shuts the motor down if bike is dropped on its side. If that's not sitting square it could be your problem.

TSSM come on bikes with a harley alarm. turn signal security module also has a bank angle sensor.

A lot of Auto elec's probably wouldn't know what to check on a Harley apart from the obvious..
You really need some form of HD diagnostic tool to check proper sensor operation.

 If anyone could help me out with the wiring diagram , would be much appreciate,

I did order 2 from the states but not 1 arrived, One of the sellers sent me a second at no charge, so thats 3 but none arrived.

all three tracked to SYD and nothing from there to Melb.......Someone upstairs hates me?

If your bike has no alarm it has a TSM so check to see if it's mounted straight and not on a angle. Does your bike have a PC3 tuner ?

Finny
I will check my bike for the location of the TSM. I would also check inside the fuel tank to make sure there's no split fuel lines or a blocked fuel filter as a drop in fuel pressure will cause the ECM to cut spark to the coils. If the TSM and fuel supply are OK the ECM could be stuffed. Any dealer could check your ECM system with a digital technician so you should consider this before spending to many dollars.

it's POSSESSED ...  

 How old is the battery? Maybe starter is robbing power. Is the bike injected or carbie, if injected check if injectors getting surficient power.

 

 Well Just like to thank everyone for the input,

The sparky caint find anything wrong, He has stript wires , He has checked everything, not once but twice and three times, Auto elec and his mate thats a Machanic say it must be machanicle problem, So when i pick it ill strip it back down and see what i have done.

Thnx again, FINNY 

Howdy Finny I just  after mine just cut out needed to take to a dealer to get  ICM  updated VIA DEGI TECH  bike now has the lastest down load my bike is a 04 carby fatboy  I am confused maybe i will have to take in once a year  to  have it  diagnosed.

 Well im picking up the bike tomorrow, the atou elec has found i dont have compression, back to the drawing board.

thanks to everyone for there help.

But i might rack ya brains soon

Cheers Finny

Finny
Do a compression test dry and then add some oil and do again. Let us know what you get.
I still think it's electrical as I know of a few TC bikes that have done over 200.000 K's with no top end work.
Good luck
