RE: After towing RV with bad batteries, truck blinkers...

Thank you

RE: After towing RV with bad batteries, truck blinkers...

OP Update: I think I have mostly figured this problem out. It looks as if all of the back light grounds are routed to the one point. From the actual light bulbs, the ground wires pass through a connector, combine at a splice in the wire harnass, and one large ground wire emerges from the harnass and is bolted to the frame. All three of these were getting old and were somewhat compromised but still worked before the towing incident. It looks as if the batteries of the TV and RV are directly connected upon plug-in. The bad batteries in the RV stressed this ground connection. I was getting all kinds of 12 volts at the back lights. I stuck a pin in one of the ground wires of a light bulb and touched the pin to the frame and the light came on. I cleaned up the ground terminal and bolt, but the problem persisted. Then I got the ohm meter out and found the splice. The splice was not working. So I peeled off the tape and saw shrink tubing with weather goop around the splice. I cut all of this off. This exposed one of these "modern" solutions. SOmehow they had four wires and they interleaved all of the strands together. Then they did a giant crimp action smashing it all into a little brick of wires. No solder or anything. I have a 1949 Sylvania TV. Still works. All soldered. So I heated that brick up and doused it with solder. Fixed. Then the lights came on. But then the next day they went off again. So I jiggled the connector and saw a light flicker. Upon inspection, the ground pin of this connector was cooked. I cut it and it now temporarily has a wire nut on it. I may just clip out this connector and solder all of the wires together. This may also be the problem with the blinkers and back up light functions. I saw evidence of heat damage to other pins as well.

RE: After towing RV with bad batteries, truck blinkers...

Thanks for the tips on the F-250 gdetrailer. Yes, I have the same rusty issues as you do/did. But I am now in Arizona, and my truck has thanked me as this has stopped it's rust from progressing.

RE: After towing RV with bad batteries, truck blinkers...

OP: Yes I'm still here. Thanks for the additional comments and thoughts. On the grounds... The schematics i found show the lights grounded individually, but upon disassembling light fixtures, i found this not to be the case. I heard mention of a single ground causing similar problems. F-250 2003. You lower the spare tire. THe ground is directly to port side of the spare tire winch on the inside of the frame. I cleaned it and it did nothing. But it was badly corroded. The last couple days I have been trying to get the spare off. Ford has a security key on the spare winch to prevent theft. I didn't have the key (like a lug nut key), so I ended up using my dremmel to cut the wire rope that holds up the tire. The flasher might be an easy one to try. There seems to be a heating angle to this problem as if everything is cool, the flasher starts off correct speed, but increases with time. I think next i will start with the night running lights and just get the voltmeter and do it the old fashioned way. Point by point working my way along the wire. Here is another weird clue.. So looking at the schematic, there is the light switch that in running light position, allows 12vdc to flow to front running lights, rear running lights, and license plate lights. Front running lights... fine. License plate lights... fine (but dim and bright with blinkers). Rear running lights.... off If i can get some running lights, I will feel safer (from police) to drive at night. Right now the truck is completely black at night and I stick out like a sore thumb.

RE: After towing RV with bad batteries, truck blinkers...

Im thinking melted something at this point, due to the fact that completely unrelated circuits are interacting. But that is a great suggestion about the fuses.

RE: After towing RV with bad batteries, truck blinkers...

Brake controller removal did not change anything. CLUE: So I pulled the tail light and had the bulb out to observe. It is a dual filament bulb. Top filament for blinkers and stop. Bottom filament for nighttime tail lights. When you turn on the turn signal the blinker speed is normal, you correctly see the top filament blinking. But then you see the bottom filament start to light up . And the blink speed goes up.

RE: After towing RV with bad batteries, truck blinkers...

updated more accurate symptoms -Blinkers.. both L/R blink -Breaks... seem ok unless maybe dim? -Running tail lights.. none in back -Reverse lights .. none -License light... ok but flickers with turns -Blinker speed... Starts almost normal speed and speeds up like when a bulb is out. I am capable of fixing this, but I need drawings and I am having a hell of a time finding Schematics or Assembly drawings showing component locations. Still plodding away at this. F-250 2003 7.3L This seems to be a single point type of failure. Like one point that is common to each of these unrelated circuits has failed causing multiple failures. Grounds seem to be distributed at each bulb, so the chance of a bunch of grounds lifting at once is small it seems to me. Maybe a supply voltage wire might be common to all of these circuits? Or yes, maybe a wire got hot? Or a wire was already corroded from age and opened up with high current? So, I have discovered that the truck batteries and the trailer batteries are connected together directly it seems when you plug in. So the truck was probably heavily charging the trailer batteries during the towing. Like.. the back up lights and also the night time tail lights are both out. They should have NOTHING to do with each other. SHould be totally different wires and circuits... Front lights all good. Look fine.

RE: After towing RV with bad batteries, truck blinkers...

Yes. The problem remains after RV is disconnected. Update on symptoms. My first post was relaying what my wife said as she was behind the vehicle. So last night I went behind the vehicle and looked myself. When you turn on full night lights, nothing. So when you are driving at night the tail is completely black. When you put on blinkers, you get a faint fast blinking. The license plate lights will dim and bright together with the turn signal. When you put on brakes, both back lights blink just like it's a hazard except dim. Front lights seem unaffected except they blink more rapidly.

... and brake lights doing weird stuff. Turn signals act like a light is burned out. They blink real fast. Both sides. Sometimes they blink a little slower, then pick up speed. If blinker is on, and then you brake also, the blinker freezes up and stops blinking. If you go behind the vehicle, the turn signal and brake lights can be seen, but are dim.

RE: Seeking refrigerator tips... in AZ and heat is hampering...

OP: Well, it’s back to being a fridge instead of a nice warm incubator. Im sure temperature wise it still needs improvement. I have not yet pulled out my thermometer. I have the tiny (its significantly smaller than it looks on TeeWee) arctic air swamp cooler in there plus a little muffin fan. I will likely upgrade the little muffin fan. Also considering expanding the water tank on the arctic air. Maybe a largerupside down pepsi bottle. Kind of like those dog bowls with a 2 liter pepsi bottle.

RE: Seeking refrigerator tips... in AZ and heat is hampering...

There is a muffin fan inside the fridge, but adding another may be my next step depending on my results.

RE: Seeking refrigerator tips... in AZ and heat is hampering...

Just placed arctic air evaporative cooler in the outside fridge compartment tonight. Also had a very small fan on hand. Also in there pointed up. Will report back.

Original Poster: Old Wizard.. I can run this refrigerator in the wilderness on a tiny bit of propane. Can that be done with a compressor fridge?

.. its ability to keep cold. I don't know much about these units, but I assume the idea is to keep the back coils cooler? I have seen one guy with a fan in the outside compartment. But that's just blowing 110 degree air on the coils. I am kind of thinking of one of those tiny swamp coolers that they advertise on TV. Any comments or education welcome. thanks..
