I have a 1995 TRX300 with no spark. I have replaced the CDI, the Stator, bypassed the neutral switch(grounded the Lime wire to the frame), Neutral light is on all the time. I still have no spark. I have 12v(11.83) at the Black w/White stripe at the CDI. If I remove the ground from the neutral safety switch Lime wire, I get 11.83v at the CDI on the Lime wire that is along side the Black w/ white on the 2 pin connector, but grounded to the frame there is zero voltage. I have zero voltage at the coil Black w/yellow wire under any circumstances. I have continuity from the Coil to the CDI on the Black w/yellow wire. Zero voltage to/from any of the 4 pin connector wires on the CDI. I am so frustrated!! Any ideas?

First off, did you get the right CDI. Honda changed the 300 CDI four times, the first three look identical except for the colour of the plug and socket, but fit the wrong one and it won't work.

 

I think CDI and the coil are ac volts not dc

 

I have pulled the neutral switch out, it's in my hand. Should it have continuity from the connector to the body, then when the pin is puched it open the circuit, or the other way around? I have continuity, 500-600ohms with the pin out or in. No change when I push the pin in. ???

 

I'm pretty sure I got the right "NEW" CDI. Ebay, but they sold many without complaints.

 

The CDI won't have the colour coded sockets if it isn't genuine Honda, so are you sure you got the right one for the year of your bike, I think a 95 has green plugs for the CDI, white was 89 to 91 and red 91 to 94. Like I wrote earlier, buy the wrong CDI for your year and it won't work. There are also some dodgy CDIs about, our supplier used to sell Argentinian ones, they were OK, they then sent one "made in Taiwan" which worked for a week then failed, the next lot were "made in China" and have been OK so far.
