Upgraded a K-line pacific with ps3, Runs and functions great. However when I apply power to track it makes a series of beeps. Does the same thing when I shut the power to track off. I have done a few other ps3 upgrades, but this is the first non mth engine I have done. What am I doing wrong?

It is a conflict in the processor.  You can try to reload the flash code for PS-32.  If it takes and clears, your fine.  If not you need to send to MTH to reboot the board.  Only they have the fixture to do it.  I have seen this occur a few times, and of course the type that also locks the board out.  G

If it runs, you will not have to send it back.

Try reflashing it. 

The only time you have to send it back is when it stalls in the flashing process.  The board is then 'bricked' and will not interact with the loader software.

You are still OK.  

 

Not true Dave.  Rare, but it happens, the unit will operate but always play morse code.  As I stated you can try a reload, but if no go has to go back to MTH or you live with morse code.  Looks like his will no longer be recognized too.  G

They all play a code when reflashed at power down.  It does it while comparing old to new code.  As the Super cap drains the process never completes.  At the next power up it goes through the morse code again as it checks code.  It then starts up conventionally.  Once that completes it will perform normally and no more morse code.  If the flash load had to be aborted during the load, it will continue morse code until a completed reflash is performed, or in rare occasions it locks itself and can no longer be reflashed.    Very rare it completes the load and works fine, but will play morse code on every shutdown.

I have posted about this before.  Since the board can no longer take a load, my recommendation is to get an RA and have it reflashed.  Since you no longer can reload flash, you can never reload a new sound file or flash code.  This should be handled as a warranty by MTH.  G

This fault they should cover even if not a ASC, but call to be sure.  Occasionally and usually rare, the loader can get some bits wrong in the memory used to process all the other files.  When that happens, the board can't be recovered via the loader, must use special test fixture which factory/MTH use to flash the programs.  G
