Goober 1,555 Posted February 26, 2023 (edited) Thanks for clearing up that he has correct CDI; the other thing i want to clear up is that the 87 TRX350D is the one-year only CDI. also @Raystrx350d when you “probe the fan lead with 12vdc,” that’s not the same as what i recommended. In the manual “oil cooling system diagnostics” the exact method is to remove the lead as @shadetree said and touch it to the footpeg. This closes the oil temp sensor circuit thru the fan control unit, which energizes the fan circuit. Being inexperienced at troubleshooting, you’re still trying to understand component nomenclature, principles of operation, troubleshooting techniques and the problems with aftermarket parts. Don’t give up just yet. Rely on the manual—read the troubleshooting guides. Also i would not use probes that pierce the wire sheath; is that what you’re using?

Goober 1,555 Posted February 26, 2023 I don’t think you answered my question about the pulse generator. When you measured resistance at the pulse generator did you measure it at the leads under the right side cover? That’s the shortest length of wire through the unit. if that’s when you got 400 ohms that’s out of spec. Share this post Link to post Share on other sites
