Wiring Diagram for a Precept 31UL?

[nriemondi]

Does anyone know where I can get a wiring diagram for a Precept 31 UL?

Our Girard GSWH-1M tankless hot water heater stopped working (there appears to be no power to the unit) and I'm trying to locate the fuse for the unit.

The fuse panel under the bed doesn't have a label for the hot water heater. Regardless I removed and visually inspected all of the 12v blade fuses there. Additionally I found and inspected 4 5w cartridge fuses in the battery/gas bin.

Any help/ideas would be appreciated, thanks!

you can call Jayco at 574-825-5861

Have your VIN# ready - they are pretty good with detailed answers

X2 on JAYCO providing fast info you need for your JAYCO unit.

I see this new style water heater from google search on its model number needs a 10AMP 12VDC circuit to operate and since this is aftermarket it may have a 12VDC drop to the back of the unit where will find the fuse you find the fuse.

You should have the info on this unit provided in a separate folder full of all your appliances that came with your JAYCO unit.

It also might be a direct wire from the battery terminal - Mine has two or three auto reset type circuit breakers for my slides and stablizer jacks direct connected directly to the battery terminals.

Thanks Jmooney and RoyBraddy. JayCo confirmed that the water heater comes off of fuse #10 on the panel under the bed (the label only shows "ODS SLIDEOUT LIGHTS"). I swapped the fuse for a good one and the Girard unit still won't power on when hot water is requested. I'll move on to contacting Girard and will post anything I find it case it helps someone else.

There is a small white button inside the heater unit. This button will restart the heater. To reset turn off the water heater, switch is inside the cover panel on the Precept, then touch the small white round plastic nob with a screw driver, restart the water heater then turn on the hot water. It should fire up.

Where is the heater unit located?
