I have 2004 suzuki ltz 400

It idles fine but as soon as you get on the throttle it chokes out. It is not a fuel/carb problem. i have narrowed it down to electrical problem due to the fact that when I get on throttle it draws more power the quad shuts off. I think it is the magneto or voltage distrubtor. Also it runs fine only when the key is turned so lights are on. If turn key to lights off mode. the quad will die. any suggestions

I would guess you have an open circuit somewhere, when you turn the lights on, somehow that curcuit is partially closed allowing the machine to run. I would start at the battery with a multi-meter and start tracing power all the way around to the CDI and coil. Look for loose connections, damaged wires and loosely grounded components. Another thought, witht the machine running, check the output from the regulator/rectifier. If it is too high, it may be shutting the ignition off. Turning the light on may be drawing just enough power away to allow the engine to run.

Great advice, I would do what DirtDemon said here. :yes:

      How did you get into Quads?
      By Mikey69
      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

      TRX350D fuel pump problem
      By semicolon
      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!

      1987 Yamaha Big Bear Electrical Troubleshoot
      By ResQ91
      Hi guys
      My 87 Bear 350 won't start and could use a hand.
      Turn key on and Oil light turns on and then slowly fades out. (I think this is key to this) No start, not even a tick.
      battery and connections good
      A Solenoid post jump turns it over
      Neutral Safety Switch wire attached and seems good
      It has not had a wire/switch on Rear Brake Pedal ever since I had it.
      Any thoughts on some other things to troubleshoot this??

      Suzuki King Quad 700 problem
      By NZrider
      My king quad 700 runs rough when cold then won't start some times but not often when it's hot. And occasionally smoke's a lot when it's cold I'm guessing that's rings but I'm worried unless it's causing the other problems
       
       
       
      All help is appreciated thanks
