Question about Ranger Communications RCI-6900F-25 CB Radio
Hoped in the car one morning and radio wont turn on has no power what so ever could you please tell me what could be wrong and can it be fixed thanks
This link will get you to the service manual and schematic. These two PDF will give you enough data to build new boards from scratch. Unfortunately radios are very complicated so it's pretty hard to nail down a problem like this without taking it apart. I don't thinkit's the power diode for a couple reasons 1st they are rated at 200v and 1kv piv (the amount of reverse bias voltage it will survive) 2nd the diodes are rated for a forward surge of 30A which is easily supplied by your battery but the fuses would have blown. If your handy I would disconnect the power and pop it open to look for burnt components. the only solution I have is re check the power connections On rare (very rare won the lottery) occasions
a bad connection will show voltage but when the radio loads it down it won't carry current.
Sorry this is much help. I'm happy to answer any more questions.
