I need a good wiring diagram for a Honda Rancher 350 4x4 I need a good wiring diagram for a Honda Rancher 350 4x4 ATV. I am working on one that blows the 10amp IGN fuse every time the switch is turned on. I have swapped the ECM to no avail, and I would like a wiring diagram and any troubleshooting suggestions you may have.Hi Jay and welcome, Thank you for the question and your patience . Should you still need assistance for information purposes only.. Initially , which version please; US TM, FM or TE/FE 02 model? Still , the described symptom almost always point to a wire that has rubbed raw or lost its insulation and that may be inadvertently touching the ground. A common area would be the steering / neck. Follow / trace the black/green wire from the fuse box and temporarily unplug any and all connector with this wire color. The idea is to confirm a grounded wire as against a faulty component. Please post back results / observations.Hi again Jay . Great! Good to hear that the issue has been resolved, congratulations. Appreciate the update and as it turned out, a faulty component; Ignition Control Module. Happy New Year!Thanks Jay for the rating and the bonus. Perhaps this may be of further help; please click HERE ( limited time download link ). It is the Service Manual in pdf format and would require Adobe Acrobat Reader or equivalent. Of particular interest would be from p. 356 for the start of the different wiring diagrams. Good luck and thank you too for the opportunity to be able to share the information.
