Cdi is a denso 32900-17e00
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.
SOURCE: no spark all ohmeter checks ok
4-pin upper left=blu/wht
upper right=yel/wht
bot left=blu
bot right=yel
6-pin upper left=yel/with blue stripe
upper right= green

mid= blank
bot left=blu/with yellow stripe
bot right=blk/wht
can you rate this thanks!
