The stock alternator may not be able to handle the load of your fridge and maybe that is what the person meant by running low. My advice would be just to buy yourself a better aftermarket alternator that has the capability of producing more power to compensate for the added accessories.
The altenator charge rate was lower than expected. The guy that tested it gave me the numbers but I can't remember exactly what they were.
We added a CTEK250S in the back of the vehicle were the 2nd battery is located in a Atwood Battery Box.
Even without a load on it, i.e., the fridge he said the charge rate was running below what it should be.
Parts are very expensive in South Africa especially ones from the states, so I was thinking since I live here in Alabama perhaps I should try to take an alternator with me when we go for our next trip. Only problem is it is Right hand drive so I understand that the altenator would have to be right handed to, right?
