I would clean and tighten all connections inside the battery compartment. I use a eurotool fiberglass brush. it cleans the connections without damaging the connections. A pair a needle nose pliers to tighten the space lug connectors. You may need to replace the circuit breaker as they do wear out. To Find a replacement on the web browser search line type"Razor E100 Circuit Breaker replacement". The Circuit Breaker can be found for about $5.99. Because of the high current draw and weather (meaning kid like pud puddles, snow and Ice) they don't have long wear lives .

Hi... My son hasnt used his Razor E100 for nearly a year as couldnt find the charger.. I finally found it and as soon as I plugged it in the plug was showing green light as that it was fully charged... When we turn the unit on it lights up but its dead... Where can I get the cheapest battery (and does it have 1 or 2)? Or you mention a reset button? Many Thanks...

There is a reset button by the on/ off toggle switch I believe. Also, the e100 needs to be pushed to about 2.5 mph before it will go on its own power.

I am not familiar with how scooters run specifically but I would bet the motor does disengage seeing how it is electric.

The battery can be recharged only so many times before it is no longer usable. You probably need a new battery. It runs with no load because it does not need much current (amperage). With a load it needs a lot more current than the battery can actually put out. The charger brings the voltage of the battery back up to normal but the current is not there due to a worn out or defective battery.

These are the instructions for adjusting the chain. They are taken directly from the manual available at http://ep.yimg.com/ty/cdn/razorama/e100e200e300manual.pdf

To adjust the chain: 1. Loosen the axle 2. Loosen the brake anchor (this is attached with the small bolt in the long slot on the left side of the rear fork) 3. Tighten the tension adjusters on the axle 1/8 to 1/4 turn to tension the chain. Tighten both adjusters the exact same amount to maintain the wheel alignment. Note: this system of adjusters is common to motorcycles and BMX bicycles so I your are not familiar with it, if you know anyone who is, they would not have a problem adjusting it for you. Chain tension: The chain should be "just not-quite snug" in other words, not taut or sloppy loose. BE CAREFUL NOT TO ADJUST TOO TIGHT. The tensioning system can easily impart too much tension and snap the chain or bend the motor output shaft. Turn the adjusters 1/8 to 1/4 turn at a time and recheck the tension each time. 4. Once the tension is good, tighten the axle and brake anchor bolt. Test run the scooter. Readjust as needed.

Sounds like the throttle is stuck in the full position. Can you adjust the throttle to other positions ? There should be a spring to return the throttle to a "off" position - and then you will have to twist to make it go. The spring may be missing.

Check the voltage output of the charger. It should be about 28 volts. Most likely your batteries are dead (over 2 years old?)

Could be the battery. Put the Scooter on a block so the rear tire is raised. Remove the standing plate to reveal the battery compartment. Charge the Unit completely 1. Using a multimeter measure the voltage across the batteries. If the voltage is below 20 volts batteries are dead - Replace batteries. 2. Now for a running test. Turn the throttle and spin the rear tire to preform a kick start. Still measuring the voltage. If the voltage is Below 20 volts or if the voltage drops quickly batteries are dead - Replace batteries. 3. If the voltage is remaining around 24 volts for a long period - then you could have connector problems, clean and tighten all connectors. I use a fiberglass electronic cleaning brush, as contact cleaners leave residue that interfere with electrical connections. The control module is simple and can be replaced with only a 24 volt relay without the kick start feature or Brake. If you want the brake then you can use two 24 volt relays still no Kick Start. For those of you who know electrical, below is circuits I developed to replace the controller. This diagram will also give you a better understanding on the Razor circuit. NOTE : This is not a schematic diagram of the Razor E100 Control Module. I designed this circuit. for my Great Nephew's Scooter. 1. The Brake is a normally closed switch that opens when you squeeze the Brake handle. 2. The throttle is two normally open switches that close when you turn the throttle. 3. The Kick Start circuit is described in the Diagram below. 4. The resistors values may need to be tweaked for best performance.

Replace the Red Illuminated Light On/Off SPST Rocker Switch 15A/250V 30A/125 - Switch number SWT-102050 should be available at most scooter repair stores or online scooter repair for about $6.00. Black wire goes to the Brass terminal lug. when removing the wires mark the location as Top, Center and Bottom and place the Black wire on top with the brass terminal. to Search Online Type 'scooter repair SWT-102050' you will see a multitude of choices

No. The switch should be off before connecting the charger. You can download a manual from Razor here... http://www.razor.com/customer-care/owners-manuals/

Probably needs a new battery. They can only be recharged a set number of times.

You might still be under warranty. If so follow the instructions on the box. If you do not have a warranty, try a different outlet in your house. If this doesn't work, look up your model number and then battery on eBay and Amazon. Hope this Helps You, if it does be safe.
