again. Also check for localized track problems.
Are there burn marks on the decoder?
You’ll need to send it in for repair!
If all else fails, reprogram the decoder address and reset CVs to default values.
27.4 Clean Track
The majority of intermittent operation problems can be traced to bad connec-
tions and poor or noisy wheel pickups on locomotives. Check track cleanliness
and quality of wheel pickups. The DCC digital packet communication strategy
performs exceptionally well in a less than perfect environment, and will often
mask bad connections until they are really impossible to work with!
27.5 The Quarter Trick
If your track does not have adequate power supply to the locomotives, then the
DCC signal won’t get through either. Take a quarter or screwdriver blade and
go around your layout creating electrical shorts every 10 feet. Your DB150
should beep and shutdown when the short is present. When the short is
removed, the booster should return to normal operation. If this does not hap-
pen, then you need to add more feeders.
27.6 The LT1 Tester
Check your LocoNet cables with the LT1 tester to be sure you don’t have any
cables that were made incorrectly.
27.7 Decoder Won’t Respond
Is the loco on powered track? If the throttle direction indicators on the throttle
are orange press RUN Key and the Y + Key
to turn on track power.
Use the “Quarter Trick” from Section 4.4 to test for track power at several
locations around the layout.
Can you select the loco on your throttle? If not, is the loco in use by another
throttle or is it part of a consist (do you see a cn in the display when you try to
select it)?
Do the settings in CV29, the configuration register, match the command station
output? If your decoder is a 14 step decoder running on an Super Empire
Builder, status editing will be needed.
Have you reset any CVs since the last time you ran the loco? If so, go back
