hi

cant get a spark on my blade engine

turns over etc fine pump primes etc

the bloke before me had made a bit of a botch of the wiring

Ive found the clutch switch and joined the wires

I cant find the sidestand wires

I can find the down wire which makes the sidestand light come on when you earth it

is the sidestand switch on the same circuit as clutch switch it looks it and its the same colour?

ta chris

What age of blade is it again Chris?

Im pretty sure you only have to bridge one or the other to get it to turn over, not spark. Is this a new build/conversion or has it just decided to happen?

Also what blade lump is it?

hi 919 carb blade I think its just after 95

it turns over and the pump fills

just no spark

gonna try some other stuff today ta

double check that all the right connections are in the right places! as thats the schoolboy error ive just done! found the wrong connector to the coils last night, and put it right! all of a sudden i had sparks! wahoo!
Have you got or bridged the bank angle sensor (if the 919 has one?), have you got power supply to the coils?

gonna check power supply to the coil when I go back out mate

ok after speaking to ab and doing a few tests myself

ive got 12v going down all 4 coil pack wires permanently

sounds like something isnt wired up right there then!!lol!

started to sort the wiring

basically theres two pins per coil

if I put the 12v ign to one side which is correct then touch a test bulb to the spade connector on the other side it lights up

this happens on both coils and surely isnt right?

mines different to yours as ive got the 954cc lump, which has a single coil for each plug. But Im pretty sure the coil should only have power when there needs to be a spark?

sorted now

ign live to coils 12v when ign on

turn the engine over and it drops to 0.01v

his wiring error somewhere

took power straight from 12v bang fired up first time with a bit of choke woohooo!!!!

WOOHOOO!!!
