I have a galaxy 44v that recieves keys up but know watts come out i have put new finals new voltage regulators b754 and the one in front of it changed the 300v redish " dog tic" thats what we...


  • The Galaxy 44 has 1 final and 1 voltage regulator not "finals." I doubt it is putting nothing out although it may look like it on a watt meter. Check VR16 (low power adjustment for the amp) and VR 13 (High power adjustment) for the amp in the radio. That radio has a variable power so make sure the pots were not turned out of whack. Check VR 14 as well. this is your AMC modulation pot adjustment.

  • Test the driver as well as the pre-driver. Check your microphone to make sure the wiring is good and the PTT is functioning.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

What would cause the the instrument pannel voltage regulator to fail on a 66 mustang? The gauges do not work mow.


It's called a CVR, constant voltage regulator, to keep all gauges with same voltage all the time, regardless of spikes. They seldom fail. I did not think we used one back in 66, but I did not start working for Ford until 1975. I would replace it and seee what happens. Let me know.

2547 channel led is dim


This is a common problem with a lot of Galaxy, Cobra and similar radios. It usually occurs from one of two things the radio has been operated on a higher voltage than it was designed for ( Called Volting) and has damaged the LEDS or it can occur from poor connections to the display board either the 8 Volt line or the Grounds check for the proper voltage at the display. Note if you ground your meter somewhere besides the display ground you may get a correct voltage reading but still not have the correct voltage reaching the display so be sure to ground your meter at the display and read the voltage there as well.

Engien revs and lights dim when i key up


You don't say how much power you  are running, but it must be quite a bit, or you have an amp you're not telling us about.  By keying up the radio, you're putting enough load on your electrical system to pull the voltage down which causes you lights to dim, rpms to drop, etc.  When you key off, everything goes back to "normal" which means no load so the engine will surge momentarily before it recovers.  Depending on how many watts you are running, you may also be affecting the alternator regulator.  Your alternator may also be a little weak.

Galaxy dx 2547


Hi Joey,
It sounds to me that the power supply you are using may be a little under powered. It's not really a bad problem as long as the voltage doesn't drop below about 10.5 - 11 volts. As for the Galaxy. I'm not real certain of the question but a Galaxy will usally use more current to make it work properly, so I would suggest a bigger ( more amps ) power supply.
Good Luck and I hope this has helped some

Galaxy 88hl stuck on 24.178


Hello radiogeek,

it sounds like you have a bad voltage regulator since you are indicating that the voltage adjusted by L17 is random. Check all of your voltages from the power supply (regulator side), and make sure they are stable. You will find that you may have a bad voltage regulation circuit or a bad capacitor in the unit power supply.

Thank you,
Shuttle83
