Still Thinking About It . . ..

I’m still working out what I plan to do next about my oil leak problem, but I want to talk to Cummins again before I try something else. However, before I do anything, I’m going to crawl back under the rig and pull off the filter and the new gasket and adapter head and see if I can see a problem.

My reasoning is that after I replaced those parts and we headed out on our Kingsland trip a couple of weeks ago, we had absolutely no leakage when we stopped at the Buc-ee’s in Katy. Every other trip we’ve had leakage by then. So something I did worked, at least until we’d traveled another 75 miles or so, and the leak returned, worse that ever.

Because of this I’m going to retrace my steps and see if anything jumps out at me

But none of this is going to happen for a couple of weeks, since this coming Thursday we’re leaving on our Christmas In New York trip. So pretty much nothing is getting done until after then.

As I mentioned the other day, when I got back from Kingsland this past Wednesday afternoon, I found a bad 50 amp breaker in our pedestal. And strangely enough this same thing happened to us back in April of 2018, too. That time it was when we got back from one of our local oil leak test drives.

But this time I had my 50 amp Tester all ready to go. And it worked great.

So I thought I’d repost this part of the blog from April 29, 2018.


A couple of weeks ago when we got back from our RV test drive we found that our pedestal was dead.

And as I was sticking my VOM probes into the 50 amp receptacle, wiggling them around to be sure I making a good connection, it galvanized me to build up the tester that I had mentally designed a few years back.

So to refresh my memory, I sketched it out on a pad and started sourcing out some parts. Then it occurred to me that rather than reinvent the wheel, I might ought to check to see if somebody already sold one, saving me the time and effort.

I didn’t find anything commercially-made but I did come across this home-brew effort.

Pretty much my same design, but I did like the box and the connector he used so I borrowed that idea, and then went all digital with it. Great minds, etc.

And here’s what I ended up with,

50 Amp Tester Finished

based on this design that I drew up.

It only took about 30 minutes to wire it up and get it put together. So the first thing I did was to take it outside to the pedestal, disconnect the coach, and hook it up.

And it worked perfectly. But in the bright sun the lights didn’t photograph very well. So I connected it up again after dark.

Much more visible on camera.

The two circuit testers check L1 and L2 for open grounds, open neutrals, reversed grounds and neutrals, etc. All of which I have encountered at campgrounds over the years.

I would have used two voltmeters but couldn’t find one narrow enough to fit two side by side. So I just swap the one back and forth as needed.

The green LED on the top left checks to see if you have real split phase 220VAC coming from the pedestal and not just two 110VAC lines coming into it. Again something I’ve seen several times over the years.


Tomorrow I get my Sweetie back home, after I drive up to Brandi’s to pick her up. It’s kind of lonely here because Karma is just not very good company.


Thought for the Day:

Common sense is a lot like deodorant. The people who need it most never use it.

  1. Hopefully you will solve your Oil Leak Problem soon.

    Your little tester was probably not to expensive to create but Progressive Industries makes Plug-In and Hardwired versions that test Voltage, Amperage, Frequency, Polarity and Bad Grounds. Probably more then you wanted to spend but they are are also Weather-Proof.

    Be Safe and Enjoy!

    It’s about time.

      Richard,

      I do actually have a 50amp Progressive EMS, but I’ve found when I’ve got a pedestal problem a lot of park people don’t want to believe it and blame it on my cord or plug, since it can’t possibly be their problem.

      This is just a quick and easy way to go right to the source without wiggling test leads in the receptacle openings.

    Have you ever thought of using a dye to see if any of the lines holding oil or seals or gaskets will actually drip a different color. The dye Might pin direct area different from where you’ve been working.
