Battery drain while sitting 03 Yamaha Kodiak 450

Recommended Posts

I have been working on my quad for a while trying to get it running right. It seems as if I run into a new issue as soon as I resolve the old one. Anyway, the other day I went to fire up my quad and the battery was completely dead. I knew it was on it's last leg, so I went ahead and swapped it out think it was the issue. After sitting for a couple of days without running the machine at all, the new battery was drained as well, not completely dead like the old one but weak enough not to turn the engine over. When I removed the new battery to put it on the charger I noticed a clicking sound when I was removing the negative connection. After fooling around with it for a bit I tracked down where the sound is coming from (see pic) it was also warm to the touch. I have no idea what this thing or or what purpose it serves but should it be clicking as soon as I connect the battery? Could this be the cause of my battery being drained? Thanks for the help, I'm not the most experienced when it comes to tracking down electrical issues.

Welcome to Quadcrazy, what that part is your showing is the starting relay. If you disconnect the battery wire and hear a click then something is staying on that should not be. 

So what I would do is take a test light and take the positive wire off of the battery. Take the test light and connect the clip on the test light and connect it to then battery terminal.  Then take the pointer part of the test light and touch the positive battery wire. With the key OFF you should not see the test light on. If you do then there is what’s called a draw on the battery. Could be a bad relay or an aftermarket part that was added to the atv.

That's a winch solenoid, if I see 2 in and 2 out correctly. Signal wire that goes to it must be on the hot wire when it should be on a switched ignition wire. 

Or the solenoid is just bad and stuck in the closed position.

This unit used to have a wench but it was wrecked and the previous owner had it removed. They told me it had shorted out when the accident happened and fried the "computer", I suppose they meant the CDI box. That's the story I was told anyway. It just seems odd that this would happen out of nowhere. As soon as I try to connect the battery you can hear a very distinct click coming from from it. Sounds like a relay but louder. Should I look into removing it? I have no plans to put a winch back on it.

Thank you, i'll see about picking up a test light tomorrow.

If that's a winch solenoid as I suspect, just take the leads for it loose at the battery and see if that fixes the battery drain. I assume there are normal positive and negative leads at the battery for the bike plus the two winch lead wires?

I'll double check tomorrow, but I am faily certain that it is just the 2 normal leads plus 1 extra positive lead, and a tiny green wire that is connected to positive as well.

If it is   the winch relay   just remove the  two activation  wires at the relay and see if there is still  the  loud click on connecting the battery..  Disconnecting the  power to the relay  doesn't stop the  relay solenoid from  firing since it is  connected to ignition switch power.

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      I need to figure out how to clean/fix or replace my neutral switch assembly On my 2008 Yamaha big bear 400 as generally the neutral light doesn’t come on when it is in neutral. To get it to come on I have to wiggle the foot shifter and hold it in just the right spot.
      I have googled it and can’t find much on the 400’s. I can’t find a service manual online and the parts manual is super vague.
      I think it is in the right side engine cover area, but not certain. 
       Any help would be great. thanks

      Hello everyone, did a search and not successful. Purchased new 2017 Sportsman 570 sp and my power steering is not working. Seems to have a mind of it's own. Works then it doesn't. Dealer says there's not a fix. Thought it was just me and it being a brand new machine with 4 hours on it. Dealership said it's this model only ? Not sure what a person in this spot is suppose to do and wondering are your thoughts mite be. Thanks

      Hi guys I'm in the market for a new ATV.  I narrowed my choices down to King quad 750 Grizzly 700 and Rubicon 520,  I own a 2006 500 Rubicon right now and I like the reliability and power for plowing.  However it is not a capable ATV.  When quading with other guys it falls short with ride quality and ground clearance.   I also have a 500 King Quad 2015 which I like and will keep it for my wife.  It is very strong and reliable also.  However my plan is to sell my Honda Rubicon and replace it with a 2020 of one of the these mentioned above.  Can anyone give me their take on one or all of these machines and why you picked what you picked?
