Hello all, I am a new owner of a riverside retro. I have the 509 model and was wondering if anyone knew what each 12V DC fuse is for in the rear electrical panel. There is no specific designation in the panel itself or in the owner's manual. Any help would be greatly appreciated.

we all had same issue you have to pull each fuse and find out what is not working and write it down. It is a pain but no other way. Better to do it now . We lost power to furnace during a snow storm and had to wait till next days to find out what fuse it was. GBA!!SVJ

David, thanks for posting. I too have not done as Joe recommends. Today I will be good and accomplish the task.

I was curious about the same thing, but my solution was to get replacement fuses for each different size. Now when one blows I have a replacement and can find the cause. When one of the 12 volt fuses blows there is an indicator light right next to it, that way you can replace it.

yes the indicator lights work good . But you blow either main fuse or reverse polarity fuse the indicator will not lite up. The main and reverse polarity fuses are 40 amp and all others are blue 15 amp. I my case the 15 amp and main blew and the person who owned the 150 before me has used a 15 amp instead of a 40 amp. Sort of a once in life time issue. I have plenty of spare fuses now. GBA!!SVJ best thing is still make sure what fuse supplies what!!

I found out what each fuse supplies, not that hard! The hardest part was putting the fuse back in it's socket after I pulled it. My box is next to the floor, Hard to get down there, AND, I can barely see the socket, bad eyes. I got er done tho and made my list which is taped on the fuse box door. Good stuff to do now that camping is over for our season.

Mark, do you have a fuse tool. It’s a plastic thing that grabs the fuse.

Woody, no. I use needle nose pliers.

A fuse tool is worth it

And a fuse tool is really cheap.  Often, if you buy a small fuse assortment, it comes with a fuse tool.

Has anyone had a problem with the fuses sparking when you attempt to put them in?  I had a couple that were blown (just purchased a 2016 177) but when I attempt to replace them, I get a spark and they blow out.  Also, are the 40 amp fuses proper for use?  The box says max of 30 amp but the previous owner had used 40's.  Any ideas?

Hi Bozeman,
Sure sounds like you have a short somewhere.  Are the two fuses that blow, the 40 amp ones?  If that's the case, maybe the battery is connected backwards, or there's a serious misconnection to/from the battery or solar controller.  The two 40 amp fuses are corrrect, they are fed by a very heavy gauge cable from the battery, capable of 40 amps.  One of them is actually in series with the 40 amp overload breaker on the frame.  When the box says max 30 amps, it's referring to the 120 vac breakers, as the TT has a 30 amp AC power cable.

If the fuses that blow are the 15 amp ones-  inductive loads like a water pump will pull a current surge and might spark a little when a fuse is inserted, but shouldn't blow.  A ceiling fan is also inductive, but not that much current.  If a water pump or fan were somehow mechanically frozen due to debris in a pump or stopping a fan blade, then that would pull a lot of current and blow fuses.

Seems odd to have two fuses blowing...  I don't know which fuse protects what circuit.  If I tested all my fuses, there's a good possibllity that other retros have different fuse assignments.  I'd say leave the bad ones out, and find out which circuits are dead, and which are live on your TT.  Then look for shorted wires, miswired things that were added.  Did the previous owner do any added wiring?

I'd also disconnect the TT from the tow vehicles trailer plug, in case that's miswired.

Best wishes,
TravelerGuy
