748 no spark - ??????
 

Have a Duacti 748 with no spark - turns over ok -
Anyone had same problem who can help ?

Thanks

Are you getting the fuel pump priming when you turn the ignition on?
Is it both plugs?
Try checking the ecu relays (under the seat), fuses etc.
Is there an alarm fitted?

no spark
 

turns over ok - fuel pump running ok - relays look ok - wouldnt know how to test them individually - checked all wiring for poor connections etc - no alarm or immobiliser ( secured by mechanical means )

Stumped - any techies out there fancy a guvvy

Have you tried......
 

........the little plastic connector thingy behind the battery/holder? It gets hot, shorts out and melts away! or something like that!


:ninja:

the plastic thingies look mint - WD40 em - cleaned em out etc - no sign of melting - checked all fuses

Are the plugs wet? If not, you're also not getting fuel, which usually means it's either the crank sensor or the TPS (throttle position sensor). Best way to check is to go to someone who has the ECU diagnostic software, like Nelly. It'll tell you instantly which one is duff.

P.S. You don't use a Quickshifter, I assume?

Thanks for trying to help chaps - but ive lost interest - selling it

NO Mr Weeks he is not joking - see thread by "trebor" in sales/wanted section ref:748r !

He obviously hasnt seen the light (but he did see a close up of a hedge......)

Syer.
