Hi

I installed a 50 amp Homelink Manual transfer switch that is not transferring back to utility voltage.

I do know Generator power needs to be present and it still does not transfer back. Both utility light and generator light are on.

I didn't do much in the way of troubleshooting yet as this is the first one I installed. Wiring harness and was connected and all the wires to the transfer switch seemed to be connected.

I"ll be checking all the wiring when I go back but wondering if there is anything I should specifically be looking out for or if anyone has any advice.

Thanks

im not too familiar with homelink, but on standard transfer switches wire 23 is taken away from ground in controller, while 240 utility power is available to transfer switch. this forces transfer to occur until the micro switch cuts utility feed to transfer mechanism. generator power does not have to be available to transfer back to utility. generator power DOES have to be available to transfer to generator.

check to make sure all wires are connected to coils in transfer switch. ive seen quite a few come out of factory with loose spade connectors.

Ooops. It does say manual transfer switch.

Well, I looked at the manual. Apparently it can be configured for manual operation with a portable generator, or automatic operation (with the appropriate kit?).

If this is the automatic version, there do appear to be the familiar fuses in it. If N1 or N2 were blown, the generator would think there'd still be a utility outage.

Thanks, hoping I find a loose connection on Monday when I go back.

I installed a new generac 9854 homelink and the transfer switch will not go back to utility power, when I push the rocker switch to return to utility it doesn’t operate the solenoid.

Well, we have to assume that the coil is working, since there's only one and it takes the switch into generator mode it sounds like.

That leaves the limit switches and the main switch that goes between utility mode and generator mode.

The rocker switch test ok when I did a continuity test, which leaves the limit switches, there are 2 for each one, what is the correct voltage and i should be able to hear them clicking if I mash them up and down, correct.

Those limit switches are a closed or open situation, but everything should only be tested with the power off from both sources (gen and utility). They normally would click, yes.
