Then what is likely happening since you're getting 12V, and the fuse is good on your Fogatti RV Tankless Water Heater - Gas - Automatic Pilot # LSB64FR is a power drop.

This is can be easily fixed by beefing up the size of the wire running between the unit and your power size. I'd recommend going with the 14 Gauge Primary Wire # DW02414-1.

It also wouldn't hurt to check your ground connections and make sure that the ground wire is running to a bare metal surface and is secured tightly, not loose.

I’ll start by apologizing for my ignorance but I’m face the same situation and do not understand the response. The wires inside my camper going to the water heater read around 13-13.5 on my meter. When I check the connection inside the water heater it not showing anything. Am I looking at replacing the wires inside the camper or the ones coming out of the water heater? Thanks!

@Kris The wires coming out of the water heater to your power source are going to be the ones needing to be beefed.

I have the same issue. I got 12 A going in, but when I hook it up to my unit, it drops to four.

@JohnnieB Have you tried beefing up the wires between your unit and the power source? Have you checked your wiring for damage and/or loose ground connections? If you haven't I'd start there first and make sure that's all good before you start changing wires out.
