If you chassis battery is at end of service by age or usage, then probably time to look for another one.
If the chassis battery should still be good, then check that your charging system is working properly. For example the older Xantrex(SP?) had the Echo Charger that maintains the chassis battery. Sometimes these would need to be 'reset'.
Best of luck, and please let us know what you find out as the root cause of the problem.
