Re: Dead silverleaf- Help!

RV-C Can bus is a standard & communication path that goes from the front of the coach to the back. My coach has two and there is a router that is under the bed that combines the two. There are 4 wires that make up the buss, Positive, negative, can H and can L. Just about everything that is plugged into this buss is powered by the buss's power.
Almost everything in newer coaches is tied into this buss where everything can talk to each other. As the picture above of the transfer switch shows it is tied into this buss. This connection lets the Silverleaf get the information as to what the voltages are coming into the coach, if it has shore power or generator power. The Silverleaf system has modules that let it talk to items that are not RVC compatible. There is one to operate floor heat. The inverters are tied into the buss thus letting you see what they are doing via the Silverleaf or to make changes to it. The light modules that supply power to the lights and the switches are all tied into this buss. Even door locks, cabinet locks, water pump, water fill and shade controls are all tied to this buss.
In the new coaches with the push button engine start, the start module talks to the Trimark module via this buss to ask if there is a keyfob nearby. If the Trimark says yes, then the engine will go into start sequence. If the Trimark does not see the right keyfob or is not talking for some reason the engine is not going to start. (Don't ask how I learned that two weeks ago)
