Question

I HAVE A 87 POLARIS CYCLONE BUT THERE IS POWER COMING OUT OF THE MAGNETO THAT GOES TO THE CDI BOX BUT NO POWER COMING OUT OF THE CDI I BOUGHT A CDI OFF EBAY THE GUY SWEARS IS GOOD BUT STILL HAVE THE SAME PROBLEM ANY IDEAS

Answer 1

GaurdrailJim's advice is Very Good,,as always

I'm chuckling at his,,"wanna spend another $30..."
To my twisted sense,,that's a humorous way to state it,,
and he's absolutely right.

Meanwhile,,(and Here's where a Manual would come in Handy) Because I do not Know the wiring color codes offhand,,,

,,,Check the "Kill Switch wire" at the CDI Box.

It may be something as simple as that,,,it's Usually a Black wire.

Jim's probably "right on the money" about Pulser Coil/Ignition Trigger,,,
Very good odds on that.
.......................................
In the Mag,,,the CDI has 2 "parts"

1)A Charging Coil to power the CDI,,sometimes called SOURCE COIL,,and other names.
It builds up the juice which is Stored in the "C" of "CDI",,the Capacitor

2)The Pulser/Trigger Coil,,,which creates an electrical impulse signal that causes the "D" in CDI---DISCHARGE.

They Both must be functional,obviously.

Pulse coils are a bit tuff to check for output with a voltmeter,,,becuase their impulse is very Small and Brief

The Discharge,,,is the electricity which is sent to the Secondary Coil/Spark Plug Coil....and that accomplishes the "I" in CDI---Ignition

Failure rate,,,,very roughly ,generalized,,,in order of probability
#1)Pulse Coil
2)Source Coil
3)CDI Box
4)Secondary Coil

All the wiring AND the CONNECTORS(Loose or Corroded) are always Suspect.

Kill Switches and their wiring somehow seem to be fairly common probs---generally.
These simply contact to Ground to "kill" the system .
Broken wires or disconnected WONT kill the system.
That's actually an "ON" condition.

OFF,,is anytime,anyplace the Kill Switch Wire contacts Ground.
Because most are handlebar mounted,,,there's "physical motion" applied to the wire.
They can get stretched,frayed,etc and make contact with ground on occasion.

Even so,,,it's NOT the most likely cause.
Just something easy to check.

Good Luck

Answer 2

You've wasted all that money on a CDI when it might not even need one.
Would you be willing to spend another $30 for the answer to your problem?
Purchase a shop manual.

Could be the pick up coil - it acts as a set of points and tells the CDI when to make the coil fire.
