So I've just replaced the cooling unit on my Norcold NDR 1492 and have all the wiring connected but the 12 volt terminal block is reading 8.6 volts at the incoming wires, so the eye brow board will not function due to the low voltage. We've run a temporary 12 volt + line with the existing ground as a test and everything seems to run just fine. Scanned the schematics and see wire 411 for the fridge but can not locate it in the front run board/fuse panel. Questions: which fuse supplies 12V to the fridge? Is there a hidden connector block in this circuit somewhere that I'm missing?

Check your domestic fuse panel. On my 2000 Magna, wire #411 is fused on the domestic panel, not the front run fuse panel. My domestic fuse panel is in the electrical bay forward of the first storage bay behind the front wheels.

Thank you "phays"!

I popped open the access panel and there it was, staring right at me. I assumed that the front breaker box was the only one and now feel good knowing that there is another area to check for 12 Volt blown fuses. I swapped out the blown fuse for a new one and now have the proper voltage needed for the fridge to work! Feels good to have a cold fridge and ice box, looking forward to having a cold beer now!

These aren't the only two places with blade fuses. All of the others I've found are contained in in-line fuse holders. If you have the Link 2000 inverter/charger control then there are two 3 amp fuses in the battery compartment. There is a 15 amp fuse on the HWH hydraulic pump that is a bear to get to and a 30 amp fuse above the start solenoid located in the engine compartment that can be seen by laying on the ground under the passenger side of the coach and looking up. There are 3 fuses on a small panel in the rear passenger side bay with the inverter, two 20 amp and a 15 amp, and two 7.5 amp fuses on the Echo Charger wires in the same compartment. The two on the echo charger fuses are not blade fuses but glass tube fuses. I also have a 20 amp blade fuse in the inverter compartment that goes to muffin fans mounted on the left wall but I don't know if those are standard equipment or something added by a previous owner.

There are five 7.5 amp fuses on the tow light board mounted on the passenger side ceiling of the engine compartment.

There are more but that is all I can remember at the moment. I recommend that when you find a fuse that you note its location and the wire number connected to the fuse and keep your notes. The schematics will help you know which circuits have fuses but not necessarily the locations. I do the same with relays and solenoids.
