Squelch won't turn off, won't go into power save mode

Power-save mode means the radio is being turned on and off repeatedly, to save power. The radio turns on, & if it hears any signals (i.e., if squelch circuit determines a station is being received), it turns on the speaker; else it turns off again to save power. So, squelch and power-save modes work hand-in-hand, and your problem is squelch circuit is either set too low, or a station is being received by the receiver. Download/look at the owner's manual and adjust the squelch circuit for a higher setting, and it should go into power-save mode again.
Good luck.

I would buy a Haynes manual. They have detailed diagrams descriptions to help you along. Just by looking at a video of cables doesn't really help us to help you solve your problem. However you can follow the Haynes manual circuit diagrams and compare it to your bikes and change cables if they seemed weathered, damaged or just incorrect!

Squelch control of ic-2000 does not function

In what way. Does it never receive? If that's the case, chances are the CTCSS (Tone Squelch) is on. If it never mutes the speaker, the squelch circuit may be defective.

Scanner acts like it doent have squelch control

If your scanner is open squelched on one channel, try blocking that channel out. Some times a channel can get jammed if someone has a mic cue button stuck or something similar.
Try locking out that particular channel and see if you get your squelch control back.

Pro 95 scanner squelch does not silence receiver regardless of knob position,subsequently receiver will not scan.

Your squelch control may be back or your control needs to be aligned properly on the circuit board. Ship it in for repair if you wish.

Scanner wont scan

provided you turned the squelch know and it didnt help, i would trace back from the squelch control to the first and second transistor you come to and that should be the squelch circuit. if you know how to check them with an ohm meter you can find out which one it is, if not you can just replace them both for under 5 bucks.

Squelch control on Galaxy DX-2547

You may have a bad transistor or detector diode that feeds the squelch circuit.If you can read a volt meter and Ohm Meter, and can solder ( Make your own repairs ) you may want to call Galaxy as the Techs there are normally very helpful.
Good Luck
