I am in need of a schematic for a ranger 2527. Its display intermittently will not come on when you turn the radio in. If you turn it off and then turn it back on it displays.
before I did any thing else I would check for a cold solder joint at the board. by turning it off and back on will kind of surge the power so it could have a bad solder joint where it hooks to the main board or on the board for the freq counter.
rfparts carry's some parts for the board you are looking for. I have needed parts and even called them and it would not be on their web site but they would have the part.
