My boys have not rode their Razor MX350 in about 2 years, its been sitting not charged nor plugged in. Recently I put air in the tires and trued charging it, the charger shows the lights being charged, switch is on the off position, the battery is warm so is the charger, but when i unplugged everything the light near the handlebar does not light up nor can I rev it up what is the problem? Also does this bike have an inertia?

cant figure out how to open storage compartment on kiki

You may have broken the bead when you rode it while the tire was flat. More than likely you will need a new tire

This is not a gasoline operated right? So the problem may lies beneath the control panel or motor it self.

It is doubtful that the battery is bad because they dont normally go bad suddenly. Usually, they will degrade slowly and hold a charge less and less before they stop working.
It sounds like you may have a loose connection somewhere. Check the leads from the circuit board to the moto and also the tabs that connect the battery to the circuit board. These sometimes break.

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...

First, take your battery somewhere and have it load tested. Fat Boys are tough on batteries as the battery sits in the "horseshoe" oil tank and is subjected to high temperatures due to the hot oil in the tank. Battery life is typically two years although I've seen some go longer and some not last that long. Have the battery tested before you start spending money.

To check the stator, you unplug the regulator at the engine case. Down inside the plug you'll see some electrical connectors. Connect a DVOM (digital volt ohm meter) to these connectors (one lead to eac pin) and put the meter in the 50 volt or higher range AC voltage. This is important that your meter be set to measure AC voltage because at this point, the voltage is indeed an Alternating Current voltage coming out of your alternator. Start the engine and bring it to a high idle. You should be reading over 20 volts AC. The book says that you should read 12-18 volts per 1000 engine RPM. If your engine is turning 2000 rpm, your meter should read 24-36 volts AC.

To test the regulator, first charge your battery to a full charge. Then connect your DVOM across the battery, red to positive, black to negative. Put the meter in the 20 volt DC range. Start the bike and bring it to a high idle. The voltage will start at somewhere around 12.5 volts and climb to about 14.5-15 volts. This would indicate that the regulator MAY be alright.

Now, have you changed any of the lights on your Fat Boy? I've seen people change and add lights to the point where their alternator could no longer put out the current necessary to handle the load. If this is the case, you may need a higher out charging system.

I don't know where you're located but $260 seems quite high for a voltage regulator.

your starter brushes are stuck you can try tapping the stater to unstick them but u will pobally need to replace the starter u can get it on ebay

i have the same issue but the charge/clean light on the razor itself wont come on or charge at all. Braun said to send it in for repair/exchange and to find out whats wrong with it.
