Green LEDs

Okay, in the main electrical bay (not front under driver's seat) I seem to remember all the green LEDs being lit when I was looking for a blown fuse and seem to remember the blown fuse LED wasn't lit. That memory seems to agree with what my manual says.

Today, looking for a possible blown fuse (water pump not running) I looked into the bay and not one green LED is lit. However, every 12v light, step cover, Hurricane Heater, etc is working except water pump (although water pump switch illuminates).

We're on 50 amp shorepower and inverter is turned off.

Are my memory and the manual wrong or is something sinister going on?

Usually the LEDs will light when there is a load on the blown side of the fuse.
If your water pump switch lights, then the fuse immediately before the pump is blown, or the pump is bad.

Humm.. On both of my 12 volt distributions panels (the Factory installed Progressive Dynamics and the self installed West Mountain Radio Rig-Runner) the LED's are RED and light when the fuse is blown and there is a load present.

No load, or good fuse, no light

However yours were Green.

Would have to see your install to comment.

Just got off the phone with an ex-country coach tech. Mine are indeed supposed to be lit green when everything is okay. He was familiar with the issue and says I have probably lost ground on a pin-switch for the LEDs. No problem, now just doesn't identify a blown fuse.

We are trying to survive in sub-zero weather up here and several funny (well, not so funny) things are happening.

Good news Hurricane Heater is working great. No issues keeping us warm at all.

Get a test light, or even better, a volt/ohm meter. Very helpful stuff.

I had that issue on my '95 CC.

The bottom used fuse position was blown, and the entire column would not light up like usual. When I randomly replaced that fuse the rest of the green LED lights lit up. My panel has three such columns.

If all of your lights are not working my solution may not be yours.
