Have a decent battery now but just wondering if it died could I hook up to a car battery and jump start it or would it cause problems. I have an 2006 V Max.
Yep, only difference is amperage which 99.99% of the time won't hurt anything at all. The voltage is the same since they are use 12v negative ground systems. I've even been jump starting my old 6 volt positive ground system from the car for quite a few years and not had a problem.
Not a problem...it's a 12v battery, it'll be just fine. The bike only draws as much amperage as it needs. If it's in a car, make sure it's NOT running...saw someone jump a jetski off a running boat battery and it fried the ECU for whatever reason, and it specifically says in the manual to never jump off a running vehicle.
