i got this atv from a friend it caught on fire it's a chinese one it's a 110cc electric start head lamps tail lamp has reverse with neutral reverse lights indicators vin number is on rear grab bar and is LXYZCHZ0250B14722 would like to know what kind it is i have many parts to order and wiring questions it runs but don't know if the wiring is correct because it will start in gear key is only a 2 wire key system i peeled the wiring apart one by one because they were melted i'm guessing that hot wire from battery goes to key and from there i went to the front brake switch and it cranks and runs but will also start in gear dont really think it should start in gear but not for sure also only has a 4 wire cdi box it's also a shaft drive too any help would be greatly appreciated i'm all out of searching options without really knowing what kind it is i do have pics if needed thanks jeff

 

I've not heard of a shaft drive 110c quad. If you search around there are VIN number decoders. Have you tried any of those?

There should be a safety interlock of some sort which keeps the quad from starting unless the brakes are applied, the clutch is pulled, and/or the quad is in neutral. Almost all chinese quads use the brake switch method. In other words the starter won't crank unless the brakes switch is closed (meaning the brakes are applied).

So is that the case? Does the starter motor only turn when the brakes are applied?

A four wire CDI means your CDI is DC powered. A two wire ignition switch is common for CD powered CDI's.

 

wow- LE, I give you credit for making it past the first sentence!

oh wait- there's no period at the end, he must have more to say....

hey jeff singer- here's the first step in getting help with your question

 

I have a power wire going to the brake switch on the handle bars thats the only way it cranks and starts if I unhook it while it's running out shuts off

 

I did use a vin decoder it says its an 05 tiwian or japanese no model not very helpful

 

No stamps or markings on the engine at all?

Honestly, I wouldn't put too much money into it. You're probably looking at a 400-500 dollar quad when it was new. Without shopping around for pricing.

 

Chinese parts are cheap and it runs so should'nt need alot brake cables body just need to get wiring figured out for sure

 

Shouldn't this thing stay running even if I take the 12 volt wire off the brake switch wire

 

Yes it should stay running unless your disconnecting power from the the CDI. When you unplug this wire are there other wired on the same terminal that also get disconnected? The CDI is what makes the pulse going to your ignition coil primary which makes the spark. If it does not have power (remember yours is DC powered - unlike many other quads which are powered directly off AC voltage from the stator) you will have no spark and the quad will die.

So the quad starts and runs with this wire hooked up... I'm not quite understanding why you would disconnect major power wires and wonder why the quad stops... If you remove power to the CDI the quad will stop. What is it that makes you think this wire need to be disconnected? Is there a problem with this wire I'm unaware of?

 

Ok lets start over the wiring got melted from a fire theres a be + wire that comes from battery fused I'm assuming it goes to the ignition switch thats melted off 2 wire switch ok I'm tacking that wire running it to the handle bar brake switch 2 wires one side makes the brake light come on and start on and if I touch the 2 together it will start and run til I release them like your activating the switch.the other side makes the thing start and run and stay running however it will start in gear reverse or first am I missing something here does that hot wire not go to the brake switch I know it goes to the key but from there to where? Hour in key turn on hot out maybe somewhere else?
