Yamaha v4 130hp
I bought a motor to put on my boat but stupidly never saw it running first ( as guy was moving house)
Installed on my boat. As i put power to it , it sparked at gauges. turned out the baullet conectors on gauge were cut off and bare wires touched. I have no spark. Thought i may have blown CDI but since i didnt see the outboard had spark first i dont have a reference .
Went through service manual...
Tested pulser coil output - Volts within spec
Tested Charge coil output - Volts within spec
Tested rectifier and fine. has power to it as well.
disconnected the kill switch at the remote.
At CDI on 9 pin connector there is 12v between yellow to black.
No output from CDI to coils.
Assumed this meant there is power to cdi so it must be faulty.
Got another CDI from a outboard dismantler but i still have the same problem.
Is there a way to bench test CDIs, Obvously since the 2nd cdi is 2nd hand theres no way to insure it is in working contion.
If i were to directly power 12v into the yellow wire on the 9 pin connector , would that work to test or does it need the other connections to oil pump control etc.
Thanks heaps
