Black is the common power to the coils and injectors. The other wire on the injector is the ground through the ECM to complete the circuit. Those are all separate circuits.

Should be pink with different color stripe for each

 

Yes true is correct the other wires are pink with red stripe & etc so now am checking to see if the ground wires that are coming from the ecm is sending the signal for the 3 & 4 coils to fire so am checking for continuity from the ecm straight up to the coils & see if i have

 

I am getting continuity on the wires but still not firing on 3 & 4 the small black connector between the ecm & coils he said to cut it out & use terminals & join back the wires cause the connector has cracks in it

 

Did you find the trigger signal out of the ecm?

Did you check the pins in the ecm plug?

 

Yea i found the trigger signal out of the ecm that doesnt seem to be the issue & the pins in the ecm is ok also so am searching for any broken wires between the ecm & coils will keep you posted

 

Heyyyy 74demon we checked the wiring 2day only to findout that we are not getting any electricity on the red wires from the rectifier but getting it on all the rest so we will check & see if we have broken wires there & keep you posted cause that might would cause the bike to do what it is doing will check & let you know

 

Heyyyyyy 74demon well we have checked everything out so far & cant seem to find anything wrong so far so what we will try next is a set of brand new plugs & see if that solves the problem will let u know what happens
