12 Troubleshooting
If you experience problems in the operation of your system, read through these
troubleshooting steps and perform those which are appropriate. This information may
help you to correct the following operational difficulties without calling your supplier or
sending your equipment in for repair:
l Power-on
l Indicator Over or Under Capacity
l Inaccurate Weight Readings
l Measuring the Supply Battery Voltage
Instructions for sending an indicator in for repair are provided in the last section under
Service Repairs.
12.1 Power-On
If your indicator does not power-on, check the following possible problem sources in
the order given. Attempt to power-on after trying each of these four troubleshooting
steps:
1. Check Battery Voltage. Required voltage is 10-17 volts DC negative ground. If
the voltage is between 9-10 volts, the indicator will display LOW.BAT. The
indicator will automatically turn off if the incoming voltage drops below nine volts
or rises above 17 volts.
2. 2.Disconnect and Check Power Cable Connector at the vehicle or AC to DC
converter, clean if necessary, and reconnect.
3. 3.Replace Fuse. Sometimes, a bad fuse can be recognized by an obvious
break in the wire filament. However, such a break is not always observable,
and getting a successful power-on after changing a fuse is often the only way
of knowing that the fuse was indeed defective.
Make sure the new fuse is the proper size and has a current rating of five
amperes. Using a fuse with too high a current rating can cause costly damage
to the indicator and will void your warranty. The same is true for substituting
wire, a nail, or any other object in place of a fuse.
Place nothing in the fuse connector except a proper fuse.
Try to power-on after changing the fuse (see instructions below for replacing
the fuse).
To replace the fuse, remove the 12 front panel screws.
1. Flip front panel out.
2. Locate fuse in lower corner of main PC board.
3. Pull blown fuse out and replace.
4. Re-install and tighten the 12 front panel screws.
4. Test Indicator and Cables to isolate the source of the problem.
