reece Posted June 20, 2012 Report Share Posted June 20, 2012 HiWe are just on our way home from 3 weeks in the north of WA and had to get the 2400 Yamaha out to charge the batteries no problems so far ,stared up and it runs perfectly , plug the cable in with only the battery charger creating any load and it starts to hunt or appears to be over loaded when in doubt check the manual but that gave me no clues.Can anyone help what the problem might be.RegardsReece Quote Link to comment Share on other sites More sharing options...
Glen and Debbie Posted June 20, 2012 Report Share Posted June 20, 2012 Hi Reece,Not very familiar with the Yamaha but I have a couple of ideas to try. Firstly if your batteries are only down a little the charger may be fluctuating voltage off and on causing the power draw to fluctuate. You could check this by observing the voltage input while it's running. Secondly, check that your inverter is off and that it's not trying to work in unison with the charger, but they should be separated automatically when power is connected. I'm not sure if the Yamaha has an economy button or not, but if it has try turning it off. Lastly, how old is your fuel?Hope this gives you some ideas to try. Good luck Glen Quote Link to comment Share on other sites More sharing options...
Rod and Mavis Posted June 20, 2012 Report Share Posted June 20, 2012 Hi ReeceDouble check that the hot water system is turned off (electric) if you have electric/gas. Our little Honda nearly kacked itself when we plugged it into our new van with the HWS turned on and the battery charger on.Needless to say the Honda's gone now Quote Link to comment Share on other sites More sharing options...
sellinup Posted June 20, 2012 Report Share Posted June 20, 2012 Hi REECE We had the same problem with our 2400 Yamy when we were camping at Inskip , under light load the thing was hunting so bad it was to bloody anoying to have on. As soon as we put a load on (air con or sandwich maker)it would rev up and run perfectly. We put it in to the local yamaha service agent,who immediately changed the fuel and said to put an additive in it as prtrol starts to break down within a couple of months and leaves a sticky gum on the butterfly. He also said that the 2400 Yamaha has a tendancy to hunt a little under a light load , and some people are putting a heavier spring behind the govenor butterfly to alleviate the problem. We haven't needed to use it since ,but have started it up and pluged it in, and although it isn't perfect it is about 90% better. I now make a habit of starting it up every so often an letting it run for about 5 mins or so. Regards Mal and Kerry. Quote Link to comment Share on other sites More sharing options...
reece Posted June 20, 2012 Author Report Share Posted June 20, 2012 Hi guys Thanks for your input I will have a look at all the points you raised.RegardsReece Quote Link to comment Share on other sites More sharing options...
The Road Runner Posted June 20, 2012 Report Share Posted June 20, 2012 Had a similar problem wth my Yamaha 2400. Took it in to the warrenty people .They said it was a bit of dirt in ths carbby. No warrenty.Cost $50.00. try again still faulty ,Still intermittent. A mechanic friend suggested wnen first starting the machine give it a good choke until almost failing.Good as gold now.Perhaps the carby needs to be totally full from the start.Runs pretty smooth now (bit noiser than the Honda).The airconditioner gives it a hurry up but at least the revs only change now with the amount of load.My observationTed Mackedie Quote Link to comment Share on other sites More sharing options...
Danny and Sue Posted June 20, 2012 Report Share Posted June 20, 2012 Hi AllHad the sme prob with ours.Really bad..Increased the idle speed up just a fraction & all is good..You need to increse idle speed a VERY small amount..

kakadu Posted June 21, 2012 Report Share Posted June 21, 2012 Hi all I have got the 2400 yamy and if I am not going to use it for a day or two I always turn the petrol off and let it run and stop by itself so there is nofuel left in carby, no problems yet always runs "ok" when I restart it not like the Honda I had.Kakadu Quote Link to comment Share on other sites More sharing options...
Tolley Posted June 21, 2012 Report Share Posted June 21, 2012 I had the hunting problem as well on my Yammy 2400. Kakadu hads the solution, I reckon. Once I started doing as he suggests there has not been any hunting under light load.RegardsColin Quote Link to comment Share on other sites More sharing options...

reece Posted June 22, 2012 Author Report Share Posted June 22, 2012 Hi Danny Thanks for your input is idle screw on the carbby and if so did you adjust it by say 1/4 of a turn.RegardsReece Quote Link to comment Share on other sites More sharing options...
Rod and Mavis Posted June 22, 2012 Report Share Posted June 22, 2012 Hi allGotta say we have a Genquip 3300 electric start that works just fine no matter what load is thrown at it.(Battery charger (70 amp),hot water system, aircon and normal power usage all at once).$1700 from TJM good warranty and really how often do you need to use the gen if the 12 volt wiring from the solar is done properly.We had 4 days of overcast at a camp at Canungra and the batteries were still happy even after heavy use every night.We could see 10-15 amps even with very cloudy conditions and voltage was smiling at the end of every day (12.9v).Life has gotta be easy or ya don't want to do it soooo use the right gear and life is good .

Webby Posted July 4, 2012 Report Share Posted July 4, 2012 We visited the local Yamaha service agent regarding this issue and it appears this is a common and known problem with this particular generator. The fix is - take it to your service agent for a "spring adjustment". Haven't had ours done yet as we were pressed for time, but will look at getting this attended to in the next few weeks.

Ian and Jill Brown Posted August 20, 2012 Report Share Posted August 20, 2012 Hi All,On our recent trip to NT, our 4yo Yamaha 2.4 generator started over revving and not adjusting to load levels.I have just been advised that the 'controller' is rs and will cost $1,500.00 to replace!Not bad for a part that sits on top of the carby and is approx. 25mm x 25mm x 25mm!!!!'Not impressed, so looks like we are in the market for a new genny (not a Yamaha obviously).Has anyone got an udate on the Genquip 3300?Cheers,Ian Quote Link to comment Share on other sites More sharing options...
Rod and Mavis Posted August 20, 2012 Report Share Posted August 20, 2012 Yep we have had the Genquip for about 6 months.Good machine although we have had a problem with the battery.The electric start is wonderful.There is no "eco mode" as with the Hondas so when you start it, it will run according to load.Ours handles the aircon,hot water system & 70amp battery charger no problems.$1700 well spent from TJMCheers from the Kyd's Quote Link to comment Share on other sites More sharing options...
Ash Burton Posted August 22, 2012 Report Share Posted August 22, 2012 Thanks KOGGERS,After reading this thread we decided on the GENQUIP 2kVA Invertor Generator @ $1129.00 delivered. We intend to couple it to a Victron Multiplus load sharing invertor and battery charger. The idea is to allow a smaller generator (pushed for room and weight) to run the AC, we also wanted an invertor for the battery bank and required a charger that was compatilble with AGM batteries. We also have a two panel PV array charging the battery bank as well and may go for a third panel. Time will tell if this was the right decision. Or if indeed the perceived need for available power anywhere was over valued. Quote Link to comment Share on other sites More sharing options...
Laurie and Helen Posted August 29, 2012 Report Share Posted August 29, 2012 Ian and Jill,We are currently in Darwin and have the 3300 Genquip mounted on the "A" frame. The thing I like about this unit is turn the key and run anything you like in the van including battery charger, A/C and washing machine without worrying about overload. We primarily use it for the washing machine when out bush but after sitting near a van using a Honda the other day I wouldn't go any other way. The Honda 2 was just sitting revving its head off.The after sales service should you need it from Genquip in Sydney is excellent as well.cheers Quote Link to comment Share on other sites More sharing options...
Webby Posted September 16, 2012 Report Share Posted September 16, 2012 I was told by a service agent in Brisbane what the fix was, but unfortunately ran out of time to have it done before we left. I approached 2 service agents on the way north with a "verbal" on the fix, but one failed to do it correctly, and the other gave me a blank stare as if I was talking Chinese. I had to almost dial the Yamaha Head Office for him who told him my instructions were correct. And yes, it was a simple spring adjustment. I now have a flyer from Yamaha Head Office showing how the spring is adjusted, so if anyone is having this same "hunting" issue, PM me and I will email it to you. Of course, if your genny is still under warranty you should take it with the flyer to a Yamaha service agent and have them do the adjustment to avoid any warranty issues. I have only had to start the genny once since it was done and I can immediately hear the difference. Quote Link to comment Share on other sites More sharing options...
kakadu Posted September 17, 2012 Report Share Posted September 17, 2012 Hi Sue I haven't had any problems with my yammy yet but would love to have a copy just in case my email is kakadu@bigpond.net.auThanks Tony Quote Link to comment Share on other sites More sharing options...
ATV42 Posted September 19, 2012 Report Share Posted September 19, 2012 Hi Reece.This is a common problem, but not readily told to consumers. Take to a Yamaha dealer for a 'spring adjustment' and it's covered under warranty.Peter Quote Link to comment Share on other sites More sharing options...
the crow and i Posted April 26, 2013 Report Share Posted April 26, 2013 Hi Rod & MavisI have purchased a Genquip 3300 and put it in the box the Honda lived in but unfortunately the filler cap vent does not close like the Honda and there is a smell of petrol in the box.How have you overcome this problem?Cheers Bryan Quote Link to comment Share on other sites More sharing options...
Rod and Mavis Posted April 28, 2013 Report Share Posted April 28, 2013 Hi BryanWe do have a slight smell in the box but the vents seem to take care of it with out any drama.Laurie & Helen have the same gen in a similar van to you so I am hoping they might respond to your question. Sorry.Cheers from us. Quote Link to comment Share on other sites More sharing options...
