remove the transfer switch cover- take your electrical meter & see if you have power to it? Do you have a Glendinning power cord reel? If yes- have you been adjusting cord length while plugged into shore power? Never do this as it causes contacts in reel to ark. If you don't have any power coming in from shore power connection- unplug & adjust your power cord a few feet longer- reconnect to shore power & see if you have power? If so, you have a bad spot in your reel contact strips- this will require a rebuild by Glendinning- to be able to use it in the mean time- unplug & disconnect the reel wires, remove the power cord from the reel & connect them( 3 wires plus ground) direct to the transfer switch. This will keep you going while they rebuild the power reel contacts & rings- I shipped mine via UPS directly to them & they took about a week to rebuild it.
