Amps Draw and Voltage Drop Question 2
Question 2 -17 Oct -------- There are no dumb questions--until now! If the furnace draws 8 amps and there is a 0.2v drop when it is on, and you change the positive wire to the furnace to a fatt...

OK,do you have an issue with your furnace? A little background-- yes the motor will slow down when voltage drops, all is normal.You are protected by the sail switch. Manufacturers build them to be in a RV, so they anticipate lower voltages.
They are rated to operate fine and safely down to 10.5 volts. That is why they have 10 volt motors in them.I have seen older Hydroflames run until voltage dropped below 10.0. If you suspect an issue, you must measure the voltage AT the furnace, not on the RV's panel,which reads the battery itself.
