Why is the battery indicator on my Inspiron 7559 not working? With a meter you should read a voltage at the positive terminals. Look for a large fuse between the batteries and the charger 12 volt output feed to the positive coach battery terminal (s). With the 12 volt lights working when on shore power means the charger is working. Sounds like a possible transfer switch or fuse issue.
Why are the lights not working on my coach?
