Battery, Voltage and Jump Starting.

[Devil]

Hey people, looking for advice/opinions/knowledge on the following.
Am a biker newbie here. Just got the first bike a few days ago.

1) Bike Battery: Do bikes run on a standard 12V system? or are they something stupid like 6V? (silly little batteries!)

2) Following on from the above question. Jump starting from a car (assuming standard 12V setup). Any issues here? Do you guys have any recommendations?

3) Now a general question related to the above. What should be the proper procedure when jump starting from a car? What shoudl you connect first, then what order etc? Any tips? Ive done it a couple of times car -> car but not with a bike.

T.I.A.

Sorry my bad

Gah, even in there people seem to have opposing ideas :/
Neg first on both, then positive on donor, then positive on dead vehicle?
:confused2

The main things are: Make sure the bike and car aren't touching, and don't run the car engine when using jumper cables. Which cable you connect first isn't that relevant.

Having a nosey through a Kawasaki bike manual recently, one interesting thing I noticed was the jump start procedure.

It said to connect positive on jump battery to positive on bike then negative on jump battery to footpeg!

Never heard of this before. Not sure if this is a common practice for all bikes or for this particular model.

easiest way is the postive to positive terminal and negative to the brake or gear shifter on metal of course. and yes 12v and yes car do good

This is common advice. The reason for making the connections in this order is that the final one may do some arcing, so the trick is to have a good earth away from things like fuel tanks and batteries. I always hook the neg lead onto the sidestand. Connecting negatives first may mean sparks flying where there be fuel...

Just buy a new battery. You are going to have to eventually.

Don't jump start injected bikes unless your cables have spike protection.
ECU's are expensive.

Thanks people. this is getting more informative!

Interesting to hear about connecting the neg to part of the frame. Makes sense now after watching my friend wire up the sub in my car. Theres only a connection to the positive terminal for power! The neg is dealt with by a wire to the chassis.

None of the connections will do any arcing if both vehicles are turned off before you start connecting jump cables!!!!

If you're still worried about arcing, make the last connection to the donor battery.

They will Slim, seen it dozens of times.

The CB125 has a 6V system, as do some older bikes, and scooters. Most bikes are 12V. However, TS had any number of issues with a 12V battery only putting out 6V Replaced the battery and his rev counter, lights etc etc worked again

Also a charging battery produces hydrogen gas, which could ignite when you disconnect the cable from the battery terminal and produce a spark. So the general rule is to make and break the connection at an earth point remote from the battery and carb(s).

I saw a guy quite recently who had been hit in the face and eye by bits of exploding battery case...it wasn't a pretty sight!
