cbr046 Posted August 24, 2022 Share Posted August 24, 2022 (edited) BOB, EDITED the title for clarity as to what brand and model of ATS so that this thread (subject) can be more easily searched later on by other members. Please note the change and do such for future posts. Thanks, TRC 40100 transfer switch not switching when generator is on. There's 122V on both legs and 0V ->gnd on neutral leg. The relay snaps closed, immediately reopens and repeat ~ every 5 minutes? I can push the relay closed and get a solid 122-0-122 at the output terminals. There's a constant green led under the relay. Shore power side transfers fine. QUESTION IS . . . . . has anyone taken these apart and found anything with the relay / control board? I don't want to replace if I don't have to. - bob Edited August 24, 2022 by Tom Cherry Clarity of Title Link to comment Share on other sites More sharing options...
