Suburban HWH not working?
I decided today to verify that my Suburban water heater needs a new 120 V heating element. I removed the gas nozzle, and pulled the cover over the end of the element. I checked, and got 0 ohms across ...

I just took the cover off and they look ok. Nice and clean. It was working fine prior to me testing the heater element. AFAIK anyway. It acts like there is a blown fuse somewhere.
No fuse involved on electric heating function....all 120V AC power
Comes from an 120V AC circuit breaker to ON/OFF switch (OEM one is in lower left corner...outside compartment----if you have one inside RV BOTH have to be on....wired in series)
From switch to set of t-stats..first to HI Temp (top one--resettable) then to Normal (bottom one) via connecting fuse wire.
Left set is 120V AC ---black wires
Right set is 12V DC (propane)...red wires
From t-stat to element...black wire) thru element and back to common/neutral bus via white wire.
Use a voltmeter and follow the AC Voltage
And as mentioned..MIGHT be a AC Junction box involved where wires are connected using wire nuts.
Just FYI.future needs....12V DC wiring
