TROUBLESHOOTING INSTRUCTIONS
Troubleshooting the WF-8700 Series Power Center

Because the WF-8930/50 Series Distribution Centers do not contain a converter/charger, 

troubleshooting will be limited to checking DC power coming into the unit and proper fuse 

board operation. See (figure 1) on page 4.

Check for Converter or Battery Input Voltage

Note:

 Depending on how the RV manufacturer connected the DC power to the 

WF-8930/50 Series Distribution Center, it could have been routed in one of 2 ways. 

1.   Power could be coming directly into the WF-8930/50 Series Distribution Center fuse 

board from the converter/charger. The battery (if supplied) would also connect to the fuse 

board.

2.   Power from the converter charger would be connected directly to the battery. A cable 

from the battery would be connected to the fuse boards input lugs.

We’ll use the first connection method in our discussion below.

Make sure the WF-8930/50 Series Distribution Center is receiving DC power from the 

converter/charger or battery. First, check that the converter/charger is plugged into an AC 

source (105-130 VAC) and is operating. Check the converter input voltage at the top lugs of 

the fuse board with a voltmeter. Be sure you have good cable connections at the lugs. Place 

the meter probes on the lugs as follows; place the Positive (red) meter probe on the 

+ POS

 lug and place the Negative (black) meter probe on the 

NEG-

 lug. If the voltage from 

the converter charger reads approximately 13.6 VDC (+/- 0.2) at the lugs, the fuse board is 

getting DC power.

If no converter/charger/battery input voltage is read at these lugs, check for an open inline 

fuse or disconnect switch in circuit coming to the fuse board. One may have been installed 

by the RV manufacturer. Also check for any other loose wiring connections.

Blown Fuse Indicators on DC Fuse Board

The DC Fuse Board has individual blown fuse indicators as standard equipment. Each 

circuit has a Red LED to indicate a blown fuse. 

NOTE: 

The fuse board employs surface 

mount LEDs which are barely visible to the naked eye. If one of the Red LEDs is 

illuminated, check for a blown fuse. If blown, replace the fuse with a known good fuse of 

the same rating. 

NOTE:

 If the replacement fuse blows again, check that circuit for a short or 

overload condition.

If, for some reason, one of the fuse board output circuits is connected to a load that has a 

switch that is turned OFF or an appliance that is turned OFF, the indicator LED will not 

illuminate even if the fuse is blown or removed from the fuse board. Turn the switch or 

appliance ON and re-check the fuse circuit with the fuse removed. If the LED still remains 

OFF, check for a broken wire to the switch or appliance. 

If an indicator LED remains illuminated with the known good fuse in place, check for 

possible damage to the fuse board at that location. If damage is found, the fuse board will 

need to be replaced.
