Furrion F50-ATS voltage test

Hello, all!

We have a 2016 Hurricane 34F that suddenly will not run on generator power. I'm getting shore power to the coach with no problems.

I followed the initial troubleshooting steps in the Furrion F50-ATS manual: I get the "thunk" when shore power is connected/disconnected, and I saw the relay move when my wife connected and disconnected the power. Then we disconnected from shore power and started the generator. (Note: Breakers on the generator are in the 'on' position, i.e. allowing current to flow.) Even after more than one minute the green LED on the F50-ATS circuit board does not light.

Moving on through the troubleshooting, testing the input/output voltages is next. Therein lies my question and the limits of my electrical knowledge.

Referring to the attached image of the ATS box cover, between which terminals do I test: Is it between RED-WHITE? RED-BLACK? or WHITE-BLACK? And what voltages between each should I be getting? (I'm using a Klein 600V AC/DC multimeter).

Thanks for your time.

Paul

Red to white and black to white should both be 120 VAC. Depending on your generator, red to black will be either 0 VAC (if same phase) or 240 VAC (if split phase).

Perfect! I suspected it was something like that, but I only have a general idea of split/dual phase. I wanted to get an idea of what I should be looking for.

Many thanks!

A lesson learned!

Thanks again for the information on the voltages. I have resolved the issue. If I may quote Homer [Simpson]: "D'oh!!!"

I did the voltage test and no power at the generator input. Now I'm concerned. I went back to the generator one last time to check a fuse I saw in a waterproof fuse holder. It was good. I took one last look at the breakers on the generator. Now comes my "D'oh!" moment of nincompoopery.

I flipped the breakers on the generator so they said "On", started the generator and...abracadabra! Power to the coach.

Tonight I learned an electrical convention. The words on the breaker indicate its state, not the direction you throw it to achieve that state. Thus, if the breakers say "Off" it means the power is...off. You don't throw them that direction to turn them off. I confirmed it by checking my workshop's breaker box. (Go ahead and laugh, shake you heads, roll your eyes. I have!)

On the plus side, I found where a lot of my electrical components are mounted, how to test my ATS switch, what voltages are going into the ATS and the voltages between the terminals. So, I learned more about my RV. That's good. I hope my goof helps some other newbie down the line.

Safe travels!

Paul
