Hi guys, i'm brand new on the site and want to thank everyone in advance for helping others in need of help. I have a problem with a 2002 Honda TRX350 where the throttle cable is getting VERY hot. I can not see any wires going to the cable and the right handle has no electrical. The end of the cable at the carb is VERY hot along with the throttle assembly. I blew the 10 amp fuse earlier just five seconds after starting the engine causing the engine to loose power. Replaced the fuse and could smell the throttle cable getting hot and could see it smoking at the throttle assembly. Any ideas??

Yeah, I'll bet that's the problem. I would pull the plastics so you can see all the wires and trace them. Should be pretty easy to find, because the wires will probably be melted.
Thanks guys, I checked the cable and nothing is burnt through. The cable itself is very hot to the touch and the insulation warms up after the cable. There is some kind of sensor in the carb and its wires dont get hot. The harness and choke cable run with each other under the fuel tank and they dont get hot. ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

i don't know much about these newer bikes..but..does your bike have some kind or pre-heater for the carb ?..maybe something for fuel injection ?..that's if yours is fuel injected ?..just wondering..if this is the case..it sounds like your hot lead to the pre heater for the carb is shorting out to ground..and it's taking the throttle cable route back to another ground ?..just a thought...you may want to trace all your wireing...like it was stated..you got a direct short to ground from a power source..check all of your wires..it will be easy to locate..it will be burnt...lol...good luck..welcome to the forums..and keep us posted.
welcome to the forum. use a multimeter check for voltage with the fuse removed and with it in that will determine voltage. (almost a sure bet) as for why if you lose ground to the frame it will follow the easiest path may be the cable. keep us informed and guys bare with me if i give vague info im a gearhead but not real familiar with atv's

Hey guys I went out in the dark and seen no sparks and the cable literaly burned a line on my finger. I removed the cable from the carb end and noticed a spark. (good thing there was no fuel fumes).. The sensor screws into the bottom of the carb has two wires. I removed them and BINGO no more sparks. Put the cable back on and problem is gone. I need to figure out what the sensor is for and how to test it. I really appreciate the input this one had me stumped.
