WFCO WF 8845 Blows fuses (intermittenly)

I have a WFCO WF 8845 converter in a Fleetwood Terry Quantum 5th wheeler that blows the 2 reverse battery protection fuses once in awhile,twice now in 4-5 weeks .The 2 batterys have not been tampered with to cause them to blow. Replace the fuses and the unit works on til the next time they blow. Can't say for sure but it seemed to happen when the furnace was runningwhy? What else could cause these fuses to blow?? Idea's anybody?

Those will normally only blow when battery cables are reversed.

Unless you have an issue with the converter.

How old are the batteries ? And what condition are they in ?

Batterys are 2 years old but check good, load tested and hydrodmeter tested

Try disconnecting the batteries then see if fuses blow when furnace is running and hooked to shore power.

Thanks f1100turbo
Sucker is gone! Disconnected batterys and discovered no DC volts on converter output. Drilled out cover rivets and discovered blown 15 amp internal fuse, replaced fuse and as soon as i pluged the converter in the fuse blew right away.I guess it was on the way out and today was the day. Now i am in the market for a new converter ,one in which i can turn on the radio and listen to it as the WFCO always caused radio interference staticwhen hooked to shore line or genset. Any and all recomendations at a reasonable price will be taken into consideration.Thanks.

Progressive dynamics inteli power converter imo.
Wfco converters are less then desirable.
Get a pd 50 or 60 amp.
