I've this data from my 1986 engine!

Under the left hand side cover there are 2 2-wire connections. One with a green and a black wire, one with a blue and a yellow wire.
Use an ohmmeter at R x 100 between both wires of a connector to check the pick-up coils: resistance must be between 130 and 180 Ohms.

The values of the ignition coil resistances are:
primary coil : 3-5ohms ( set ohmmeter at R x 1 )
Secundary coil : 25.000 - 45.000 ohms ( set ohmmeter at R x 1.000 )
For a correct measurement ALL leads must be disconnected ( also the spark plug leads )

The CDI cannot be tested with a simple measurement. Suzuki dealers have a special tool to test CDI boxes.
But checking the pick-up coils and ignition coils good will indicate an defective CDI.

The wires on the CDI:
Blue: PU coil 1 ( cyl 1-4 )
Yellow: PU coil 1
Green: PU coil 2 ( cyl 2-3 )
Blue : PU coil 2
Orange/white : +12v ign coil 1-4
White : switched coil negative side ign coil 1-4
Orange/white : +12v ign coil 2-3
Blue/yellow: switched coil negative side ign coil 1-4 ( and signal to tachometer )
Blue/white : ground

Thus, you must have +12V on both Orange/white leads.

I have a 1996 gsxr 750 and its not getting fire but getting power everywhere else what should i check. ? Also witch wires on the coils are positive and negative??


Hi, Billy and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting, leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or CDI or electronic control module.
7. Faulty CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

How do i test cdi


swap your coils with the cylinders that do have spark. if it changes then you have a bad coil(s). generally cant test cdi's. It's a "replace with known good part" kinda test.

Not getting any spark to the plugs


for no spark the cdi is a better bet and there is no test for it but process of elimination buy cheapest part first you can use a test light to see if your getting power from your startor to the cdi and coils if the cdi has power when you turn it over its 90% its the cdi
