Battery Quick Disconnect/Onan Generator

[brad05]

When I use my quick battery disconnect my Onan generator starts to make a humming noise likes its priming and the start light comes
on? Is there a reason its doing this? My rig is a 2017 Keystone Raptor 355TS

Do you have an automatic transfer switch?

Mine does that also. Was told that it needs to be wired correctly at the DCM or the disconnect switch. I disconnect the plug wires next to the manual start button on the genset until I can get it in for work.
