sounds to me like its been rewired
the EMG start relay is usually NOT a continuous duty relay and would normally burn out in short order
also NOT normally a latching relay
normal operation would have included a diode based isolator to do the battery charging and a light duty starter type solenoid/relay for the emg start
you can change this system back to factory, but i see no problem with it the way it is , Except for remembering to push the Button to start the process
The emergency start solenoids are indeed for continuous duty. They sometimes do dual duty on some motorhomes. They engage when you push the Start Boost button and release when you let go. Then, depending on the model RV, there is either a simple Ignition activated wire that keeps that solenoid closed for charging on the coach batteries, or it has a BIRD type system that supplies the 12 volt signal to close the solenoid to charge the coach batteries. The CHARGE rate is a LOT less than the amp draw when engaging to start the chassis engine. Most motorhomes use the same solenoid for both purposes. Doug
