i've jumped mine a few times each winter, never had a problem doing that, althought the motor is turned off tho

 

I believe you can actually un-plugg your rectifier,and then jump it off. After it starts and you take the jumper cables off , you can plug it back in and test it to make sure it is charging properly. It should read 14.2 volts at 3000 RPMs. if it is way higher than that your recifier is bad.


Also if you dont wat to "jump" you quad for fear of possibly damaging your Starter. you could alway charge the battery with you vehicle, then take the jumpers off while cranking it.

Busmechanic, Were getting off topic here, but I want to help you understand how electricity works.


"not true. the starter will take more amps if they are available. and they are. try it on yours and see what happens. maybe nothing. but, you will have a hoter starter and cables than usual. it would be better to jump from another small battery"

Ohms law covers how electricty is measured in a circuit. Volts =amps x resistance. The part of your statement about the starter taking more amps if available, doesnt fit ohms law. If i understand your argument correctly, youre saying if you put a 60 watt light bulb, in a 110 volt circuit, and the circuit has a 10 amp fuse, the bulb will pull 10 amps? If it had a 25 amp circuit, would it then pull 25 amps?
The way it works is this
a 60 watt bulb, in a 110 volt circuit, uses .545 amps. Power= volts x amps
From that, we can get the resistance of the bulb. resistance= volts divided by amps, which is 220 ohms. So no matter what potential the circuit has, in a 110 volt circuit,the bulb will only draw .545 amps, because it has 220 ohms. You could plug it directly into a nuclear reactor that has 50000 amps, and it would still only draw .545 amps.
This applies to the starter as well. If the starter draws about 5 amps, in a 12 volt system, then the resistance of the starter is about 2.5 ohms. So no matter what the cold cranking amps of a battery, it will only draw 5 amps, because of the 2.5 ohm resistance.
But if the motor is running, and putting out 16 volts, instead of 12 volts, the starter will draw over 6 amps.(16 divided by 2.5) Which doesnt sound like much, but is a 20% increase over 12 volts.This could cause damage.
Ive jump started many motorcycles and quads over the years, and as long as the motor is off, it wont hurt a thing. 12 volts is 12 volts, and amps is determined by the internal resistance of the starter, no matter what capacity, the battery has.
Sorry about the off topic rant, i just want to staighten out a popular misconception.

 

Try removing the stater coil behind the battrey (very simple) cleane the connections and reinstall, try that. If that did not work measure 13 volts at the two small wires "When you hit the start button" If you read voltage then replace the coil, If no voltage is there then look up stream motor run button, and start button, make sure all connections are clean and tight. Good luck

 

I do understand ohms law. electrical troubleshooting is a big part of what I do for a living. but, thanks for the lesson. and, I am not trying to sound like a a$$. you and I could have a very profound conversation about this. in a perfect world you are right on. since it is not perfect. there are exceptions to the rule. I am not going to get into it more than that.

 

Might check the connections to the battery. Might be corroded.
