Univolt and Fuse Panel - Can Somebody take a Pic?

mello mike · 06-27-2009, 07:42 AM

Can somebody please take a picture of their fuse panel, univolt system in a 1972 model. My Sovereign 12v system has been altered quite a bit by the POs.

I'm also curious what circuit/fuse the exterior lights are on? Are they all on one circuit?

Mike,

Here are some pictures from our 76 center bath. Let me know if you need something more specific.

Regards,

Kevin

Excellent! Thanks Kevin. Do you happen to know what circuit your running lights and tails lights are on? What is attached to those in-line fuses? I have those but they aren't connected to anything anymore.

I can check in the morning when I get to the office.

Mike,

The small diameter lines with the in-line fuses (shown with the yellow arrows) go to the ammeter. Mine feed into the wall with the cord bundle.

The running lights are not on this circuit.

Here are some scans from my OM.

Thanks,

Kevin

Mike,

Here is the running light schematic from my OM.

Thanks, Kevin and Aage.

The exterior lights I was referring to are my running lights. They don't work at all now.

Do the running lights and tailights go through the fusebox? They are only connected to the umbilical to the TV, I thought.

Looking at the '74 Service manual, it shows that near the TV connector (very front of the coach, centre) there is a 12 volt 25 amp circuit breaker. That becomes the blue wire, which goes to circuit #5 on the Univoilt: "charge". In other words, that completes the circuit to charge the battery from the TV.

OK, found it: on page 209, it shows what I said above: the only connection that the tail lamps, turn signals, backup lights and running lights have comes from the 7-pin connector that plugs into the TV. They DO NO go through the fuse panel of the trailer.

And the 25 amp breaker up front is only to protect the charging circuit.

So if you are having problems with running lights, etc, look to the TV connector, or the sockets and/or wiring for the running/turn/backup etc lights.

Now here, if you are talking about the round outdoor floodlight, that one is on the brown wire, circuit #4 in the Univolt.

The "steplight", which I believe is the one outside, over the door, is also connected to the brown wire, after it passes throught its switch via a brown/yellow wire, so see above.

Hope this helps.
