The current models of automatic standby generators will have LED indicator lights on the side compartment of the generator. A green LED light will indicate that the unit is in AUTO mode and is ready to run, or is running properly during a utility outage. The yellow LED light will indicate that maintenance is needed. The red LED will indicate either that the unit is switched to OFF or that there is an alarm detected. If a yellow or red LED are present, you will need to check the generator's control panel, as it will describe the type of maintenance needed or the alarm present. This information can be found in the owner's manual as well. You can find a copy of the owner's manual online by searching the model or serial number of the unit here

all lights blinking means that your exercise time is not set

Most of those chargers have a fuse in line between the battery and the charger which you should check. They are two stage chargers meaning when there is a large voltage drop, they go to a high rate charge until battery voltage reads about 14.3 - 14.6 VDC then drops to a float volatge and normal float voltage should be about 13.33 VDC. When they go to a high rate the light turns red, when they go to float the light turns green. When the fuse blows the light stays green because it doesn't see any voltage but the charger isn't doing any work.

You need to pull in two yellow wires called N1 N2 for sensing 220v. One red and one white called 23 and 194 those are your 12vdc transfer wires. And then last of all your 12vdc from battery charger. Hope this helps
