Have the battery tested. If it is over 5 years old just replace it. The 90 AMP is fine unless you have added a lot of electrical equipment. Again, talk to Rob @ PJ Grady and he can help you with your choices. I would strongly recomend you replace the "Ducey" before it fails. You may also have an issue with corrosion on the "big" connections, the battery, the starter, and the alternator.
