burned up my controller dcx300R7
 

My fairplay ZX 4.0 -6P was reversing out of shed and the controller started to smoke up. What would cause the controller to burn up? aren't these protected by solenoid/resistor? It had the stock dcx300R7.

The resistor and diode do not protect against catastrophic errors. Typically in Sepex drive carts 3 things cause the controller to burn up. A direct short on the input or the output side. Overload or excess amperage draw. Motor failure.

Had a guy tell me his DCX control failed so he put the old stock control back in, 100 yds later the motor failed on the reduced stock control...

thank you for the response I'll check the motor out, its only a year old motor so Im hoping it's not dead. What would cause and overload or excess amperage? batteries are also 1 year old 8 x 6 volt setup.
