Hello Everyone,

I am in desperate need of some advice and some ideas. I purchased a cheap atv (550 krusher, Atomik/trident) online, it was a write off as it had rolled but had low hours and was very cheap. The guy who delivered it started it and drove it into my garage. The next day i went to start it and after it kicked over a few times there was an electricity surge and the starter relay fuse melted and i lost all power.
I am a complete novice when it comes to engines so this is all a learning experience for me.
After i changed the fuse I regained power but was still unable to get the engine to start. I took the spark plug out and found that i was not getting a spark from the spark plug when the engine was kicking over (when the plug was grounded against the engine).
I also found that there seems to have been a surge in the 5 pin changeover relay for the ecu and a surge (melting) in the stator connector plug)
I Have since spent 2 days researching and buying different things to try and fix the issue.

Here is what i have tried
-new battery
-connecting jumper leads
-checking every fuse i can find
-using a mulitmeter to check the starter relay
-using a multimeter to check the battery
-using a multimeter to check the starter coils
-hard wiring the killswitch
-hardwaring the burnt out connector for the stator wires
-removing pull starter and accessing the stator (which doesnt look damaged by my novice eye)
-changing over the micro changeover relay for the ecu (stealing the one for the 4 wheel drive function)

The engine seems to be kicking over fine and all the auxiliary components seem to be working fine but i just cant get a spark. Is there anything else that could be the issue?

I have found the manual online and believe im following the correct start up procedure.

Fyi The motor has an ecu ignition.
And i cant find an cdi, i dont think this bike has a CDI

Any help would be appreciated!

 

First off, don't "hardwire" anything unless you have to, change the type of connectors if you must, but don't hardwire a kill switch, especially as some are earth to kill, some earth to run and some feed positive to ECU. The terms ECU and CDI are almost interchangeable, a CDI box is an ECU but an ECU does not have to be a CDI. Until electronic fuel injection systems came out, 90% of bikes used CDI ignition, now the ECU runs both ignition and EFI. The ECU needs a signal from the flywheel to tell it when to fire, most CDI systems also use a separate coil on the stator to power the ignition, but some use battery power for this. You need to find which wire does what at the ECU and test that they are doing it.
