I have 3 separate tracks with 3 185 watt power packs and 3 legacy power masters.  There is one double switch over from track 1 to track 2, but I have insulated sections with no power wire in them. Track 3 is completely separate.   It appears that when I run Track 1 some of the power goes to track 2, or vice versa. I've doubled checked to make sure there are no power crossovers to track 2 or vice versa

Also track 1 is set to command and track 2 & 3 power masters are set to conventional.

Could there be an issue with the power masters being too close.

Also after running the legacy unit a short while I get a sound like a horn.

Any suggestions



Thanks

I suspect either incomplete isolation between the loops or a phasing issue.

Disconnect your power leads from the track.  Use a multimeter to verify that the center rails of loops 1 and are isolated.  If there is any connectivity, examine the insulated pins (or whatever you are using) to look for any connection between the center rails of the loops.  Once you are sure  that the middle rail of the loops are isolated, connect the power leads with the power off.

If the tracks are isolated  - good.  Turn on the power and set both loops 1 and 2 to the same voltage.  Measure the voltage on the center rails across the gap.  I should be 5 volts or less.  We're looking for a phasing issue here.  If you see a high voltage, change the power feed to one of the loops and test again.
