No red light after charging

Hi Linda.
not sure if this will help you out,i found this on the internet.
Battery Charger Troubleshooter
When there is a battery failure, there is a possibility it was caused by a bad battery charger. When the charger is only plugged into the wall, it should show a green light. If there is no light showing, confirm that the outlet is good. If the outlet is good, it is very possible that the issue is with the battery charger, not the battery.
If the charger is plugged into the battery only, it should show a green light. (If you have purchased a new charger within the last year, you will not get a green light if the charger is only plugged into the battery. You will get a green light however if the wall charger is just plugged into the wall and not plugged into the wiring harness) If it does not show a green light, it is likely that the charger is not making contact with the battery. The most likely reason for this is a faulty fuse on the wiring harness. This fuse is a 2-amp automotive fuse, and it should be replaced with a 2 or 3-amp fuse available anywhere that sells auto parts. The fuse can blow out if there is a short in the charging system, or if the plug-in end of the wiring harness comes in contact with a battery terminal.
When the charger is plugged into both an electrical outlet and the battery, there should be a red light showing on the charger. A red light showing indicates that the charger is in contact with the battery and is actively charging the battery. Once the battery has reached a voltage level that is considered "fully charged" the red light changes to green. If after 24 hours the light has not changed to green there is no cause for alarm! Remember that when the light is red, the battery is being charged, and you will be able to use your system. After 24 hours or so, your battery is as charged as it is going to get, and if the light is still showing red you should disconnect the charger and go fishing. Replacement chargers and parts can be purchased directly from MarCum's website.
If you are really concerned about your battery, consider getting a basic volt meter to check the voltage of your battery. They can be bought for less than 20 dollars and will show you exactly what the voltage level of your battery is. If after 24 hours of charging your battery should have at least 12 volts (ideally 13-14 volts) and as long as it is over 12 volts it will work. If it is not at or above 12 volts you should consider replacing the battery. If your unit starts to malfunction while you are fishing, it would not come as a surprise that the voltage has dropped down to 11 volts or lower.
If the charger is plugged into the wall and battery, and you get a blinking light on the charger, it is very likely that the battery is faulty and should be replaced.
Batteries are an expendable item, and must be replaced periodically. Any store that sells ice fishing electronics will stock suitable batteries. You can also buy them at a specialty battery store, or by ordering one from our website.The batteries that you should use are the "Sealed Lead Acid" variety, they are 12 volts, and range from 7 to 9 amps. The more amps the battery has the longer it will run on a full charge. Your MarCum unit can be powered off of any battery that is 12 volts, even a large automotive or deep cycle batteries will work.

battery charger is blinking geen Google Search

in the hand book it states that the charging period for new batteries can be up to 6 hours

hopefully you will find the charger near the machine ? ( a plug with a lead ) simply plug it into an electric outlet ( plug hole ) and connect it to the blower ( you will see a hole in the blower the same shape as the end of the lead on the charger) if the charger has lights on it ( usually red and green ) you will see the red light come on,leave it charging until the green light comes on. or charge it over night...hope this helps

First measure the voltage of the batteries at the charging socket of the joystick.

• If this is a brand new item out of the box, if this were my item, I would send it back for an exchange. The charger never turns green because the battery never gets a full charge. Because of that you won't get a 7.4volt reading out of the battery, Either the battery is not taking the charge or the charger is malfunctioning and not charging proper. The lights may work for a bit while the motor won't spin because a light takes far less voltage than turning a motor. Because you don't know if it is the battery or charger and it is new I have to suggest to take it back. The sooner the better. Messing with it will just void the warranty.

John the red flashing light indicates a low battery When you charge the battery your charger should be showing a red light for power and a yellow light. When the batteries are fully charged you should show a red and green light on the charger. Now if you have a voltmeter plug the leads into the two outter holes of the charger port located under the front of the joystick.Without the charger plugged in you will be reading the battery voltage. Fully charged it should read 27-30 volts if you are only reading 20-24 volts then the batteries are low. If you have an onboard charger plug it in and you should read the charger voltage of 29-32 + volts If you aren't getting that voltage then you have a bad charger if you are getting the charger voltage then you have bad batteries and they need to be replaced Hope this helps you

You have the four coloured lights to show battery state Red - irrecoverable; Orange - 3 to 6 Volts in the battery, Oximiser will attempt recovery; Yellow - 6 to 12 Volts in the battery, Oximiser will charge and and optimise and Green - Full charge, about 14 V, the Oximiser will maintain the charge.

On the left of this you have a Green light to show that the Oximiser is connected to the mains and on the right you have a Red light to show that you have connected the charging leads thewrong way around, i.e. the positive charging lead is on the negative terminal and the negative charging lead is on the positive terminal. This light should be off.

when the red light is on while charging it means it is at less than 25% charge let it charge until the light is green
then tryy connecting it to the computer

May be a bad battery or charger.You said new contact toshiba for a replacement.RICHARDM69

According to the manual, the red light comes on while charging when the battery does not yet have enough charge to sustain a 3-5 minute shave. The green light stays on steady while the razor is charging, and blinks when it is fully charged. If your battery life is short, they might need to be changed.
