Just got my Slash couple of weeks ago. First RC I have ever owned. Took it out of the box and charged the battery with the supplies car lighter port charger. Truck ran great. Didn't like the fact that I had to charge my new RC from a lighter port i ordered the Traxx ac-dc convertor wall charger. Plugged it up and it seemed to work fine. Due to a death in the family was unable to try and run the truck again till today. Placed the battery in the truck and nothing would happen. No lights at all on the ESC so thought the battery might have set to long and needed recharging. Plugged up the convertor then the charger. Red light came on solid as it should in ready mode. Plugged in the pack and charger stayed solid red for several seconds and then blinks on and off red. Will not charge. What am I missing here.
