It gets very cold here some mornings and both of our SP 400s are hard to start. I usually wear the battery down trying to start them. They run fine when it's warm out or they have warmed up. So I don't want to mess with the carbs and have it effect something else that's fine now.
I am thinking of installing remote terminals to jump off my truck or hook a charger too.
Can the atv handle the increased amps that a truck battery puts out?

 

I've used my truck and a battery charger on 70 amps to start my ATV when the battery went dead. Both ways worked fine.
I think it should be safe, but maybe someone else can tell you for sure.

 

I agree, I think it would be alright, but I would disconnect as soon as it started.

 

Just make sure the truck is not running and the quad will be fine. The quad starter was designed to see 12.6 volts max, and by using internal resistance, it pulls a safe current. But if the voltage is high (like having a truck alternator putting out 15.2 volts, it will draw too much current. Youll even hear it...itll spin much faster than normal.
Current is determined by the voltage, divided by the resistance of the load. Its The device resistance (starter motor in this case) which determines the current draw, not the theoretical max of the battery. If more voltage is applied, more current is produced, because the internal resistance of the starter doesnt change.

 

Thanks guys.

 

yes dont have the truck running or you could cause server damage as that alternator puts out some major amperage and can fry the wheelers electronics.

 

I did jump start my old Yamaha Exciter 570cc snowmobile years ago..........And burnt out the Voltage rectifier.................But I did have the car motor running!!............caper........

 

Get yourself a couple of these.

I plug my SP 700 in all winter. Never have a problem starting when it gets below zero.

 

I have a small solar trickle charger from Canadian Tire. It works pretty good and never over charges as it stops charging at night. It was only $10.

 

I have a battery tender. That's how I charge it if i am not going riding right away.
