What cylinder kit and battery are you using? If you used the M150 with anything but the 12 volt battery, you're asking for trouble. Also, make sure you have a charger capable of actually charging a 12 volt battery. Most R/C chargers are not capable of this.

Do you have the 490 motor or the 480?

Just so you are aware, many, many international retailers will not even sell the SCK without either assembling it themselves or not at all. And Systema does not warranty the kits at all. You guys want to save a couple of dollars to do assembly yourself on a gun that is 100% alien to all but a very few. There are at least 4 common problems that happen with self-assembly that can be the issue here.

1) Solder. If you have experience soldering, this is not an issue. And by experience, I don't mean you did it once in shop class. I mean you have done it hundreds or thousands of times. You can over-solder very easily, leading to heat damaged terminals, solder flux and solder in motor windings or on motor housing, leading to a potential short circuit.

2) Electronics failure. This can result from problem #1, and can also happen due to mechanical damage to the boards during assembly or during the soldering to do the burst mod. Have you done this?

3) Battery/cylinder incompatibilty. If you try running the M150 on anything less than a properly charged Systema 12v battery, you run the risk of damage. They sell the proper batteries. Use them. They also sell the proper charger, but you have to shop for an aftermarket one to charge 10+ cells, as well as do proper discharge. The MRC Superbrain 989 is a very good one for the PTW batteries. I've seen guys try to run the M150 with the 7.2v Systema battery and get blown fuses. 9.6v will also do that. M90, M110 and M130 need 9.6v PTW batteries, don't cheap out and get them built by anyone. M150 requires 12v.

4) Wiring damage. To be blowing the main fuse, this would mean damage to the EL-003 (switch board) to motor wiring. This could happen if you don't take proper care when routing the wiring through the receiver holes.

You may also have a motor failure, as James has described. You will need to provide a hell of alot more info if you want help on this gun.
