Re: testing batteries for E300s scooters
You haven't given me much information, Wendy, such as why you want to test them, or if they are in the scooter. I'll presume that they are not connected, and that you think there may be a fault in the scooter. To test them you will need a multimeter, and if you own ones of these you would know how to test the batteries. They are too expensive to buy for a one-off job, and I won't confuse you by telling you hoe to set up a test lamp.......Hook up the batteries to the scooter and see if it works....Don't forget that the red wire goes to the POSITIVE ( or Plus ) terminal, and the black wire goes to the NEGATIVE ( or Minus) terminal. If you are still having trouble, take the battery to a battery supplier and ask him to check it for you. Please don't forget to rate this answer.

Have you tested the Battery? That light indicate a low voltage from the battery. Also check the battery terminal connection and be sure to clean and tighten them and have the battery serviced (topped off with distilled water and have fully charged). Test the battery for voltage and put under a load test. If the battery fails any of these tests, replace it, it may be working enough to start now but it could give out without warning.
have the alternator tested,Also have the battery tested to make sure you have not gotten a faulty one, IF the battery loses charge over time,you may have a wiring short cicuit that drains the battery, Make sure all lights are off,including the glove box light when car is off. I have had to replace the alternator 4 times on my 02 Kia due to factory defect alt.Had bench tested(good) 3 times,but would not work in the car.Mike
That's often the sign of a worn-out or defective battery. They appear to charge but don't store enough energy to work. It's also possible the motherboard's power circuit isn't working. The only way to know for sure is to have a known good battery as a test, or to try your battery in another computer. If your computer works with a good test battery, or your battery causes another computer to shut down, you know you need a new battery. If the trouble continues with a good test battery, you'll need to have the computer serviced.
If you see the dashboard lights it does NOT mean the battery is charged enough for the starter to work. Charge it (overnight) or try to jumpstart the car. Or if you want to be sure measure the battery voltage. If it is less then 12V you need to charge it.
Stop by any good local parts store (Autozone, Advance, etc...) and have them do a FREE charging system test and to LOAD test your battery. I'm suspecting alternator, but have tested to be sure. (also make sure your alternator belt is tight and not slipping or broken)
This is the wiper motor failing...But to be safe unplug wiper motor,turn on wiper switch,connect test light to negative side of battery or good solid metal ground and stick probe in connector.if it is not working and the test light is not on then the wiper switch has failed.....and if the test light comes on at connector the wiper motor has failed..Since it works intermittently have an assistant to work the wiper switch and test a number of times to be sure.You can buy a cheap test light that will be good enough to check this at any auto parts store...BEFORE YOU BEGIN YOUR TEST MAKE SURE TEST LIGHT
HAS GOOD GROUND BY CLAMPING TO NEGATIVE SIDE OF BATTERY AND TOUCH PROBE TO POSITIVE SIDE OF BATTERY TO ENSURE GOOD CONNECTION...LIGHT WILL COME ON.
you can try this it use to work on older cars but i'm not sure about the newer vehicles i haven't tried them i have the proper tool for checking current draws now anyways
remove the NEG battery cable
take a TEST LIGHT and clip the test light to the NEG cable you just removed from the battery
then stick the probe of the test light in the NEG post of the battery MAKE SURE ALL THE DOORS AND HATCH ARE CLOSED
if the test light LIGHTS up you have a current draw
then start pulling fuses one at a time till the test light goes out
once you find the fuse that shuts off the test light
then you will need to find out what is on that curcuit
then elimenate what is on that curcuit
hope this helps and hope this works for newer vehicles
let me know how you made out
OK this is the part where You take out your test light or multimeter (best) and start chasing down the disconnect. begin at the battery and then go right to the starter to begin with, then the accessory side of the ignition switch. Once you covered these items continue from battery again and go item by item till you find the problem. Don't forget you need a good ground, regardless so make sure that is good as well. Only do testing after verifying that your battery is fully charged and can withstand a load test, otherwise all testing is invalid. After finding the problem, check the charging system to make sure it's working.
