2001 Honda TRX 250 Recon - Blowing Main Fuse

Recommended Posts

Hello Forum Members. I have a 2001 TRX 250 Recon that I purchased about 6 months ago and now experiencing problems with the main fuse blowing when I rev up the engine.

Let me give a little history on the ATV. The previous owner says that the battery is approximately 1 to 1 1/2 years old. The ATV will start when jumped, but will not restart immediately after turning off ATV. If the battery is charged while out of the ATV, the battery will last about about a week until it's dead. The ATV ran great, the only problem I had was the engine would stall after a hard acceleration. A quick pull on the pull start and I was good to go (battery would not crank motor).

I installed a new battery and that is when I started having the problem of the 15A Main fuse blowing. I would start the motor and rev it a couple times and then the fuse would blow. I replaced the battery with the old one and replaced the fuse, thinking the new battery was the problem, and the same thing happened. Did the installation of a new battery cause my problem?

I read in other posts about the regulator/rectifier being the cause of the main fuse blowing, so I unplugged it and the problem wasn't resolved.

Any ideas or places to start looking? Could it be a bad alternator being it sounds as though the battery wasn't charging?

Thanks in advanced for all replies!

Phil

I would start by removing the racks and plastics, then trace every inch of the wiring harness. You are looking for signs of chaffing allowing the harness to short out. The bad news is sometimes the damage is inside the taped up harness and wont be visiable. A good multimeter and service manual would definately help

i would start by looking at the wires like the other guy said first ..then i would check all the wire plugs and clean them and make shure all the ground connections are clean and making a good connection... then i would replace the voltage regulator .. they are not 2 expensive ... and go from there .. the regulator is a usual cause of blowing fuses on that machine .. but i would check the other thing first b4 spending the $$$ on parts ..

      Hello, well back to where I was last year with this carb. Took my 250 to the mountains for the first time this year and blue smoke, too much gas again. I can't believe that this carb gives me this much trouble. Seems like the choke is stuck but the cable moves freely. Anyone else ever experience this issue? Do you think a new choke cable would maybe resolve this?http://www.quadcrazy.com/atvforum/images/smilies/arghh.gif
      OK it was the choke. Put on all new cable and plunger and she is running 100% again. So now the question is, is the carb getting worn out where the plunger needle goes in the small hole and when I use the choke the needle end doesn't get lined back up with the hole?? We'll see how it runs and now that I know what the issue is I can always pull the choke plunger out and reinstall if I start having this issue again.
