My qustion concerns how the LP pumps are actually switched on or off. Looking at the RF Electrical Manual I see the following wire discriptions,
LH Pump wire is Black/Green
RH Pump wire is Black/White
2 Way Valve is Black/Orange
Crossover Switch is Red/Green + Black/Orange
The 2 Way Valve is a power on power off type valve that fuel flow is directed to either side when power is applied. I assume that the Red/Green is power on the switch and the Black/Orange when switched takes that power to the 2 Way Valve.
My question is how are the LP pumps actually switched? It looks to me that when you flip the selector switch you power the valve but I don't see the connection to direct which pump to operate.
The reason I am looking for this information is that I am using a 6 way valve that has inputs and returns for each tank and the surge tank built into it. the valve is motorized and works by changing which lead is powered. The change over switch is a on/on switch that changes the polority on the valve thus changing the feed and which pump is powered. What I am trying to work out is if the pumps on the original RF setup are actually being turned on and off in some manner and not by the switch alone.
Thanks Peter
