The first thing to check is the batteries and see if they are dry and out of water or if they are over 3 years old, they may be bad. You should have a small digital multimeter for some testing here to make this faster. About $15 or so at most hardware stores. Batteries can be load tested at most places that sell them. Be sure and take a photo of the hookups! Get bac
back to me with the results and we can go from there. All follow ups are included in our fee.
Did you have the battery load tested? That is the only way to really tell what the actual condition is. And that voltage you read wouldn't be good if the converter is working..........you want to see about 13.7 VDC there. That looks like the OEM unit and there is an upgrade that is all electronic now and has no AC ripple which can be easily inserted in your housing. About $199 for a 45 amp unit. Takes about an hour to change out and it comes with good instructions. Progressive Dynamics is the company. Hope that proves helpful here. Please get back to me if you need more
It needs to be tested for output with a volt meter. No way of knowing how long one will last, but not taking care of the batteries won't help as it has to work harder and if the batteries short out from no water, then it can ruin them as well. Some, like the Progressive Dynamics model has adjustable charging which can extend battery life. And you are quite welcome! A positive rating on my assistance would be greatly appreciated when we are finished as it is the only way I get compensated for my time.
It seems like that...........BUT testing them both would tell you in just a few minutes.
