Thank you all for your replies and help. We have been quite busy with our electrical
problems which have gotten worse. So here's an update. We appreciate any input.
The bad battery was taken out as soon as we noticed it was boiling. Its shaped has changed and unfortunately the other batteries' shape has also changed. At this point, it is clear that our batteries need to be changed and will be.
In addition to this, we measured the output voltage on the alternator
and it indicates 15.5V, which is obviously too high. We assume it has an internal regulator
and will have the alternator
checked and repaired or changed if needed. The alternator is now disconnected and we have been charging our batteries with our generator
only. We do not have any solar
panel or wind vane
We wonder about the following:
- We have an external regulator
(Balmar max charge). Shouldn't it have picked up the high output of 15.5V?
- Does the regulator measure the output or only the batteries charge and adjust Amps when the batteries reach the set Voltage?
- Until yesterday our batteries were dying but holding in at around 12.05V. Last night, they went down all the way to 10.5V. What could have triggered this additional deterioration? Is it normal or does it indicate we could have an additional problem?
- We want to make sure that we rule
out any other issues, especially since we will install new batteries. Our main two worries are
1) A ground leak and we will look for it. Any advice?
2) A short (but I assume we would then see Amps going out right?)
Thanks a lot for your help!
