Aux voltage should be around 13.6Vdc. 14 or more is too high it's likely the voltage regulator is failing..

 

its was probably higher when it was 1st fitted, as the electric board have brought down nominal voltages its reduced !  

System with linear transformers normally have DC-DC voltage regulation after rectification, AC voltages wouldn't matter unless under the the required DC voltage.

14V is still high. There are plenty of other system check engineers would do on a service over just voltage.

Charging current you would check amperage in series with a good battery. Before this test I would discharge the battery by measuring the system current in alarm and standby.

Thank you, this is most helpful.........👍
