we got a sunl 110 brand new in 2008 for my daughter she rode it maybe 10 times in the first 3 yrs.(cause it was such a pain to get running) and in that time we bought about 3 different batteries for it and had to jump it to run most the time... its sat the last 2 years, now we want to try and get it going for my son.....alot of people told us the "Alarm" systems on them drain the batteries and if you disconnect the alarm they will run fine. has any one else had this issue and/or give us some insight into the batterie problem, or tell us where to find a wiring diagram on the internet for these things.....

 

Yes, remote modules do draw current all the time, and will eventually drain the battery if the quad sits around for long periods. And batteries that sit discharged (even partially) are damaged over day to weeks. It is absolutely imperative that you keep a maintenance charger hooked up whenever the quad is not in use. There probabaly is a huge difference between different remotes too. It is easier to design a remote when you don't give a hoot about power consumption. It takes a lot more skill to design one that uses the absolute minimum power.

Yes, the quad will run fine with the remote disconnected. But you won't be able to shut off the quad with the ignition switch anymore. You''l have to use the handlebar kill switch instead. This can be fixed with a jumper, but most just opt to learn the new routine.

But if you are going to let *any* quad sit for an exended period you also need to have a maintenance charger hooked up. Batteries go dead all by themselves. Think about it - if you left your car sit for two years would you expect the battery to still be charged? Would you expect it to start? I wouldn't, and I'd bet you'd have to fill the tires with air too .

And finally, are you even sure if your battery charging system is working? If that isn't working then you'll just be ruining one battery after another. Start up the quad and leave the headlights off. Use a meter to measure the battery voltage on the 20 volt DC scale at medium fast speed. You should read 13.5 to 14.5 volts. If you don't your charging system is not working.

I don't have a wiring diagram that is specifically for your quad. The best that can be done is to look at other 110 wiring diagrams and figure out what is the same and what is not. But all this is premature. If your battery is toast it needs to be changed, and then we need to see if your charging system is working first...

 

This quad did not sit, we have had this problem since the day we got it. we had the new battery that was charged, put it in, it started and ran once maybe twice, from then on we would have to jump the thing to get it to turn over and start....every time... with every different battery we've had. we did not let it sit for long periods then tried to ride it (except over winter, batterys we're pulled and charged before getting put back in) this happened every week till we just finally gave up and said no more, now its sat for about 2 yrs and we would like to get it running for our son (if possible without to much hassle)......we never used the remote anyways so thats not a big deal..... But what is a jumper?
we will try to check the volts but first we need to get a new battery! if it is not holding a charge then what would be our next move??? thanks for the imput...

 

It really sounds like your charging system has never worked.


A jumper is just a wire connection between two points. It usually also implies that this "connection" is bypassing something that isn't working. Think of a set of "jumper" cables that you use to connect a good battery across a dead battery. Sometimes a "jumper" is a movable connection that is used to configure a circuit. For example think of a computer mother board that has jumper plugs that you move around based on what memory type is being intalled. In your case this "jumper" would be a wire connecting two pins on the remote connector to replace a connection that was normally made inside the remote module.


I suspect your battery is so far gone that you won't be able to do any tests on the charging system until you get a good battery installed. Then do the battery voltage test to see if you get the 14 volts +/- 0.5 volts as outlined in the last post.

But we don't want to ruin this battery too. So you'll need to have a maintenance charger at the ready so that you can keep the battery topped off while we measure and fix the charging system. We also need to see right off the bat if it is simply a case of the battery not getting charged back up by the quad when it is running, or is something actually sucking the battery dry while the quad is just sitting there. This involves removing the main fuse off the battery and inserting a current meter in its place set to measure amps on the 10 amp scale. Then we can monitor current going into or out of the battery precisely, and this will give a big clue as to what is going on.

But first get the new battery and a maintenance charger (never charge at more than 2 amps), install the battery, and do the charging voltage tests as per the last post. Then remove the main fuse and hook up the maintenance charger. The charger will keep the battery topped off, and removing the fuse keeps the battery from being sucked dry by some sort of fault on the quad (if there is one).
