sixwheeledbeast Posted April 16 Share Posted April 16 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.
