We’re going to provide three different methods of charging a motorcycle battery: using a jump-starter, using a trickle charger, and jump-starting the motorcycle with another
If the battery is still in the vehicle, attach the positive to the battery terminal then attach the negative to a ground point away from the battery. Many people use a point on the engine block. With the battery removed, you don't have a ground point to connect to, so make the last connection away from the battery by using an extra ground cable.This number of “0” in the size is the number of “Aught”. For example: 8 AWG = Eight Gauge. 2 AWG = Two Gauge. 1 AWG = One Gauge. 1/0 AWG = One Aught. 2/0 AWG = Two Aught. Allowable Amperage of Conductors for Under 50V (Per SAE J-378) Note: Since most wire is rated at 85° use the 80°C values.
A motorcycle battery can jump start a car if the motorcycle is running. Connect the positive and negative leads of the jumper cables to both batteries. Have one person rev the motorcycle to around 4000 rpm’s and have the second person try to start the car. There are a few other things that will aid in starting the car with the motorcycleNote: Both motorcycle and car should be switched off as you begin. #1 Connect jumper cables in the same order as with jump-starting from another motorcycle – attach the red, positive clip to the positive terminal of your dead battery and attach the other red, positive clip to the positive terminal of the car battery. Either the fuse will go, or the wires will. If you're dead-set on using a bike to start another one, plug everything up and trickle charge it for a while, and then disconnect and see if it starts up. Or, just bump start it. With two people it takes maybe 10 seconds tops. true.
