There are several things you can do to avoid electrical problems or to fix the situation, including:

  • Shut off all electronic appliances from the power supply and reset the energy breaker.

  • When a fuse burns out, breaks, or becomes black, substitute it with a new one with the same amperage rating as Keystone originally fitted.

After switching the circuit breaker and replacing the fuse, don’t connect too many electronic devices; doing so can increase the load on the system and cause issues.

2. No Cranking 

The battery terminals are likely the problem. Therefore, look for corroded ends and weak connections unless the RV turns on but not cranking. Check disconnected negative and positive terminals on the battery and do the following:


If the ground wires are loose, you need to tighten the connection. You should also: 

  • Connect the battery to the engine block and straighten the wires.
  • If the problem is still there, check to see if there is a connection damage

  • Turn on the RV again, and If none of these solutions works, you may need to replace the battery.
