Question about Cobra 18 WX ST 40-Channels Base CB Radio
My cobra 18wx stl ll blows fuses when plugged in
There are a few common reasons the fuse keeps blowing:
1. The transmitter final transistor is bad, it usually is directly connected to the 12v source and not switched by the power switch.
2. The power wires were accidentally reversed I.E. positive to ground, neg to 12v. There is a protection diode on the circuit board that did its job and is now shorted. it will keep blowing fuses until its replaced.
