I am attempting to trouble shoot a Transfer Switch issue. In either shore power mode or generator power mode I show good current to the input lugs on the TS. However at the point where the current should flow out of the switch ONE of the two lug bars does not have current.
Am I correct in concluding that the switch is bad or maybe one of the terminals on the relays is not making contact?

Second question is-How does the inverter play into this switch. Why is it connected to the input side ?

Third question- Where can I find a suitable replacement. The switch is a Todd Electronics TS 450. Most of the ones I see on line do not seem to have the input lugs for the inverter.

Also is this a shore power priority or generator priority switch ?
Thanks, AL

On my Coach, one side of the TS has both shore and Genny inputs. The other side goes to the inverter. On mine the AC voltage comes off (electrically, maybe not physically) before the inverter charger circuits. Most TSs are generator priority as is mine. Amazon has some transfer switches.
