You will soon become a Chinese assembly technician. You will also be ready for a job if China takes over the U.S. , just kidding.

Well Any way about going and inspecting A Scooter to see which parts it needs?? I am going to tear it down tonight all night and create a list so i can go tomorrow and track down some parts

You would be a lot smarter to put the battery and cables on and start it. And then see what doesn't work. If you take apart first, it's likely you could introduce more problems. Once you know all of what you are dealing with have at it. Guessing requires buying more parts than needed every time.

I am not messing with the engine stuff just tracking down where the black amd red wires are to replace them for the battery.

i found the red wire that was cut.

[richardv]

Yup! That be it. Now you have a sample of what you need so, now figure out what lengths you need and go to a shop that works on snowblowers, snowmobiles or the like and get some replacements. It doesn't matter if both are black, the electricity doesn't know the difference. You could get some red tape and wrap some on each end to ID it.

Turns out the red and black battery wires are cut and needs replacing. I will get them later and a battery. After that i will be able to test the scooter and see if she starts.

could i use any battery like this from walmart for my scooter??

[cyborg]

No,, termination is wrong,,,&. Not enough cranking amps

[Bashan]

You need 7 amps but the more the merrier. It has to be 12v but the amps can be as much as you can stuff in the battery box. If you ever jump the bike DO NOT start the jump vehicle, just hook up the battery.

Here you go get a 4 gauge red for the positive terminal on the battery going to one of the Solenoid terminals and 6 gauge black from the solenoid to the starter.

I just recently rebuilt a wiring harness and I bet you're going to have at a minimum, 2 wires per battery terminal. 

One Heavy gauge (14~16 gauge will do) Red cable going to your solenoid and one red coming from your regulator/rectifier to your + terminal on your battery (and possibly branching off to other hot circuits)....

Your negative side post will have one heavy gauge cable going to frame (most likely black) and and one green wire running off into your harness for ground....

Granted, these scooters very wildly, but I have 4 150cc's and them 4 wires I listed are all the same.

While that's true for "starting" your scooter, running an over-sized (amp-hour) battery can cause the stator to be over-worked because it's constantly charging... Heat is the number one enemy of stators and having the coils constantly energized produces excess heat.  

I once had purchased an over sized battery for my car, and kept burning up alternators and couldn't figure out why... Took it to the dealership and the mechanic filled me in that the battery and alternator are rated for each other and the larger battery was over-working my alternator... I got the smaller battery, Viola... Never had an alternator problem again..... 

One thing to keep in mind, these scooters have 6, 8, 11 and 12 pole variations...But yet they mostly have  7Ah batteries, so there's obviously wiggle room in choosing a larger battery, I personally would not go beyond 9~11Ahr's with 11/12 pole, 7~9Ahr's with 6/8 pole.....

A very good tip thank you mr Martin
