My apologies.....
I just noticed that you have a 2003 model year Four Winds
That would mean you have a 3E version (if 10 gallon) or a 9E or lower version (if 6 gallon) which would have completely different wiring scheme.
The 120V AC Electric side should be 'direct' wiring and the propane side would use 12V DC
But you stated 'jumper wire' still connected ????
Wouldn't be any need for 'jumper wire'
So post exact model number.... (outside compartment or on a data sheet inside RV)
Examples
GC6A-8E or GC10A-3E
Unless your Class C was actually built in 2004 on a 2003 chassis
2004 Atwood redesigned Water Heaters using DC for controls on both electric and propane.
RED wire------12V DC POS
GREEN wire----12V DC NEG/GND
BLUE wire-----12V DC to Fault Light from circuit board
WHITE wire----12V DC to circuit board for electric function ---circuit board then sends DC power to relay that triggers 120V AC to element
Orange wire---12V DC to circuit board for propane fucntion
All wiring to/from circuit board and On/Off Switches is connected via wire nuts at backside of water heater----so look there for which wires are connected together if you have the 'new Atwood version'
