'99 DSDP: how to isolate GFCI circuit?
I have a '99 DSDP and need to replace a defective GFCI receptacle in my kitchen. How do I totally disconnect the power for this circuit beyond switching off shore power? Thanks in advance.

The circuit breaker for that set of outlets, passenger side of coach , should be marked in the 120 volt panel above the bed . If you have the optional 2000 watt inverter you should shut that off.
I had to replace the kitchen GFCI in my coach ; the outlet is in a fiber box and the replacement was 1/16" to wide and I had to widen the box with my Dremil .
A handy tool to have in your coach , aside from your multimeter , is a non contact 120 volt circuit tester , that will tell you if the wires are HOT , before you touch anything with a screwdriver.

Thank you kindly for the guidance and safety tip. I’m still sorting out the ol’ girl’s electric systems. I do have a non-contact detector along with my multitester, actually, and use it as my first line of verification. Have a good week.

Michael , as per your PM , here's a maintenance schedule , 100k is the milage for the second valve adjustment .
The second pdf is about the fuel system , but I don't see in either document , anything about injector service . I will keep looking .
I can't attach files to a PM so I'm posting the info here.

Thanks, Skip. This info will be very helpful. I watched a YouTube on the HEUI and now I've got something else to worry about, given the miles and age. Seems like it's a "not if, but when" item. I've for sure got to upgrade the post-pump oil tube to the steel version. Again, thanks for your good help.
Michael

There are three things to consider when talking about 120v AC power...
1)Shore Power
2)Generator (make sure it is off and auto start disarmed to prevent it from repowering the circuit when least expected)
3)Inverter...many ( or in newer coaches MOST ) of the outlets are powered via the Inverter. It's very possible for them to be live even without a shore power or generator source applied.
For me...I prefer to trip the breaker for the circuit I am working on if I know which one. If you don't mind shutting off all the AC power...and if your panel is laid out like mine...Tripping the two 50A breakers on the left will cut the distribution of power from the Shore or Generator from the Main AC bus. And tripping the far right 30A breaker will cut the supply of AC from the Inverter which powers the items on the Inverter sub bus. Those three breakers will cut just about everything that is AC powered off.
