My new Generac Guardian Series Model 5504 generator has a trickle charger which is installed in the RTS Pre-wired Automatic Transfer Switch. The correct battery (series 26R) is installed in the generator, and the generator is programmed correctly and set for automatic operation. However the battery goes dead; it appears the trickle charger is not working properly. Is there a way to check the trickle charger operation directly?
