I guess I need a little more convincing that the sensor is looking at air temp. High capacity battery chargers need to know battery temperature in order to modulate charging rate. I think that is the purpose of the sensor. I agree that attaching it to the negative terminal is an excellent idea.

Jim my evaporator thermostat opens at 48 degrees as measured at the lower end of the evaporator tube as it exits the case. Never going to get cold air at that high setting. Bought a thermostat with an adjustable set point. Plan on installing it this weekend. Think it will help a lot. That high setting also tends to cycle the compressor too frequently. My compressor only runs briefly before it disengages.

Hi Lori, in your particular case as you appear to be using a branch circuit you could not change to a GFCI with a higher rating as the personal protection afforded by the device would be compromised. That also would be strictly prohibited by the codes. I should add that RVs are not considered ice melting equipment.🙂

On the topic of GFCI protection there a few different ratings including GFCIs which are set to trip at 30 miliamps in order to minimize nuisance tripping. These are typically used for heat trace and other ice melting systems and are not intended to provide personal protection from shock. As I leave my RV unattended for extended periods I use a 30 miliamp rated GFCI to protect my feeder circuit and still have the protection of the 5 miliamp rated devices at a branch circuit level in the motor home.

It sounds like your 15 A adaptor has worked in the past and this is a recent problem. If my assumption is correct then I would look at the GFCI first. It might be tripping on fault current. They are sensitive and perform their function well. If that is the case then it could be a problem in your cable, or adaptor. Or it might just be a bad GFCI. They don't last forever. Hopefully its not coach related. That could get a little more complicated.

Thanks for that picture Rob. I have been using the term accumulator and receiver/dryer as if they were the same. I imagined that smaller systems typically combined the 3 functions. I don't see a dessicant pack or a filter in your picture? If there is any filtration going on then it is solely by gravity and the perforated screen.

There is no way to determine how much oil is left in the system without removing the components and draining the oil. Might be able to drain the compressor in place. Draining the condenser is not too much of a challenge. Draining the evaporator does not look like fun. Your going to be replacing the accumulator as it has a filter and dessicant so that amount is the only oil which you would add. If you had a very slow leak then you probably don't need to add oil to account for the other components. Too much oil will reduce the efficiency of unit. Not a good thing because the performance is not that great as is.

Ken the probe is sometimes held by a small clip or just the friction of the cooling fins. It should be in contact with the cooling tube. The temperature of the coil also increases nearer the outlet so maybe you should place it in the original location and see how it performs. I bought one with an adjustable setpoint for $45 on Amazon.

Teslas are so yesterday. Here is the 2023 must have electric vehicle.

Thanks Ray, Somehow I confused myself with even less effort than usual. I wanted to make sure that I understood the principle correctly because I bought an adjustable evaporator thermostat so that I could play around with the low side temperature set point. My existing evaporator thermostat opens at about 45 degrees. Hoping I can lower that temp a few degrees in order to improve the feeble performance of the unit.

I trying to wrap my head around this idea that the pressure at the evaporator is going to be lower than that read at the compressor. Seems to be contrary to what I thought was fundamental to the principles of pressure drop. Somebody explain to me the errors in my thinking.

That is an interesting product. I am going to buy one. I know de-sulphating works because as an experiment I restored a nearly dead bike battery. Only problem was it took a month with the small 6 amp charger I was using.

Learned something new. I did not suspect that the bag sidewall was 1/4" thick. A large diameter coarse thread sheet metal screw would do to stop a leak temporarily on the road. Wouldn't hurt if it leaked a little as the air compressor could keep up with it. I haven't been leak free since 2005. One more leak probably wouldn't make much difference.

I've been toying with the idea of buying a set of mud and snow tires like the loggers and dump truck operators use around here for those trips when I'm feeling adventurous. I'm been told that you can plow a wet field with them.

Paul I'm using the traditional "chain" chains. They are harder on a vehicle however they seem to be more effective based on my limited experience. I just creep along and remove them as soon as possible.

Gary I have hydraulic jacks so I can usually raise the rear tires high enough to install the chains before I get in trouble. Not sure how much the chains would help if you are already buried. Been in your situation. Best of luck.

I always carry tire chains in all my vehicles, summer and winter. Been stuck on wet grass here in Or. So far chaining up and with the help of a friendly 4 x 4 I have never had to call for a tow.

Lot of good information. On a side note I did some research and experimentation and decided that " wet " applied spray graphite was an excellent lube for the rack and pinion assembly. Does not attract dust and produces a lower coefficient of friction than traditional solvent lubes. Several applications allowing each to dry yields best results. Wish I had of taken some amp readings for a baseline before. Noticeable increase in speed in my case.

The City of Portland is trying to shutdown the states largest UP rail oil terminal. Serves Washington State, Oregon, and California. The oil barge companies working on the Columbia River are now being targeted. No more dirty oil, ride a bike is the hippie chant. Activist successfully shutdown the largest power plant in the state last year after PGE had invested 100's of millions in clean air upgrades. Cost of electricity is going thru the roof here. Ratepayers are footing bill. Same for natural gas. The developer of the Jordan Cove Project, permit revoked after a 10 year struggle, stated that the company had no intention of ever investing in new energy infrastructure in the United States in the future. Going overseas. Who is surprised?

When I'm leveling I carefully and incrementally level the coach while keeping the frame rails parallel at all times taking into account tire load balance. From the picture it appears that your frame rails were substantially out of parallel at the time. Also noticed a stress crack in the radius of the fiberglass. I wonder if some handling problems which owners complain about could be caused by twisted frames as the result of improper leveling procedure.

Ryan as others pointed out that would be fine so long as the conductors are 12 ga.

Be careful to understand that a GFCI doesn't provide overcurrent, arc, or fault protection. A GFCI only senses an unbalance in current flow due to a path to ground. The 15/20 A designation is the manufacturers non-continuous load rating.

Good boost pressure, lots of smoke , low power. Excessive air intake restriction?, Or fuel injector? If you can feel and hear a chugging sound probably points to a cylinder misfire.

Check the resting voltage of the old batteries after a full charge and same with new batteries. If the difference is less than .25 V then I would use them. When I have a battery failure due to a bad cell I don't automatically replace all.

Someone here is an experienced insurance agent and could provide an answer. I forget who he is. However I'm guessing that if one's policy prohibited the use of a space heater, or maybe a particular breed of dog for example, and in the course of a claim an adjuster noticed a violation, whether accessory to the claim or not, then that would be cause to deny the claim. Worth considering when big money is at risk.
