Answer
Hi Frederic:
Replace the battery. Make sure it is of the correct amps. I believe your car call for around 80 amps cold cranking power. That should provide enough power for all those electrical features on that baby.

When a battery bubbles, it mean all the acid is gone and you are running on just water, which can over heat as the generator tries to charge the battery.

However, also check the battery cables and make sure they are clean and have a good, tight connection.

I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis.
