Landing light switch causes JPI to reset

[Jrob]

Hi all.  I have a question for the mooney experts.  I have a 1981 231 that I bought about a year ago.  Last week I had a routine oil change with a shop that has a good reputation but this was my first encounter with them.  They are based at a small uncontrolled field and I took off mid day without my landing light.  On approach at my home field, I switched on my landing light and my JPI "reset" like I had just flipped on the master and the MFD flickered a bit but stayed on.  I tried one more time and same result.  Out of the fear of bursting into flames, I landed without the light.  After a routine landing, I shut the radios down and flipped the landing light switch.  Same issue with the JPI (MFD is off at this point).  Called the original shop and they said, "nothing to do with us, have it fixed there."  Has anyone encountered the same issue? Something get pinched with the cowling coming off? Any thoughts are appreciated.

When you remove the cowl you have to disconnect the landing light. It is easy to forget to reconnect them. If they are disconnected the hot wire could be shorted to ground. When you turn on the light it shorts out the electrical system until the breaker blows. Take it back and have them fix it, or do it yourself.

Which JPI do you have?  The primary ones, 900 and 930 should be connected to the master relay back at the battery.  The other models are connect to the bus up front.

I forgot to clarify.  I have a JPI 700.

I had the same problem with my 201 check the battery voltage before start up you will probably find it low but it will start.  I sent the JPI 700 back and they downloaded my last flight and saw a momentary voltage drop.  they recommended I get a new battery and that solved the problem.

Hey Buddy,

In support of the long running debate of battery manufacturers...

Which battery did you swap out?  What did you replace it with?

Gil v Concorde, wet cell v sealed gel cell?

How many years old was the old one.

Are you back to single lines again?! You were into paragraphs!

I love paragraphs, proper spelling, and using the correct word. I'm just not very good at it.  Siri has started adding to the challenges.  The MS software hasn't helped much lately either.

I was spending a little extra effort on the topic and a little less on the mechanics of writing.  It was important to me at the time to not accidentally bash the less favored battery manufacturer. I am still seathing internally about batteries.

I have updated to the most recent iOS (9.0.2) and it has made editing more challenging as well. Combining the MS challenges like putting the cursor in the right spot may not work the way it is supposed to. Then it lets you write too many paragraphs. Followed by not allowing editing the last paragraphs...

i am looking forward to going flying.  The price of gasoline is making it very favorable.

Best regards,

No need to seethe. Just put Brand C / Model X batteries into your Brand M / Model R. I went for more cold cranking amps and got the -CGX model (I think) (-AGX?). New in Dec 2010, great capacity testing in late Jan 2015, still cranking in ~3-4 blades (of my 3-blade prop), even the day after my pitot & transponder test that had landing light and belly strobe on for over an hour. The joys of LED lighting!

So much for seething internally! Now I'm seething and rolling on the floor...rotfl(?)

Please, no replies neccesary,

And just for the record, this example of your writing (or Siri's) was nearly flawless. Only a failure to capitalize the last "I" was noted. Well done you paragraph spewing machine!

Oops. Upon further review, there was a space violation between "either" and the "I" early in the paragraph spewing. Sister Mary "No Mercy" Marauder would only have mangled two of your fingers for that violation.

Good thing we can't do cursive on these threads. Broken rulers and body parts would be everywhere.

My 16-year-old nephew can't read cursive. The boy is driving, and has never been taught (in school or at home) to read or write cursive. Thank you, American public school system! He can't read what I write in his birthday card every year . . .

but I have to agree, Anthony's posts are much improved! My visit in Jan last year must have shaken something loose. He got a dose of broken Southern verbiage, mangled by 9 years in WV, directly into his brain over bacon and eggs.    At least he didn't complain of aural injury afterwards.

The last time I saw Anthony he was "Y'all" ing everyone and asking who was serving grits. You indeed have had an impact on the man.

Wait for the the man with the pants to chime in. A while ago, I got to speak with Patrick on the phone. Those two were planning the first NJMooney fly-in. 201er took me to my first NJMooney fly in.  He got to train me on how to get in a Mooney and sit down. Really, it was sit down and then get in the Mooney. My wife had dropped me off at the airport. Flying with 201er was inspiring and it lead to a few hours learning with Cris in his Screamin' Eagle. Cris and I took in another Fly-in at Sky Manor. I'm still not a fan of the wires off the end of the runway on final approach. I saw Marauder at my third NJMooney fly-in. I was the only one driving a Chevy to a fly-in that day. Meeting Hank for breakfast was extra special. We got to talk plastics processing machinery and Mooneys in front of our wives at the same time.  Dr. Peter showed me that super refreshed leather interior in person. I saved Alan's V-tail story for last.  We started at the home of El Presidente (near Pittsburg) with the twin IO550s. then we headed west instead of for home. I was so well rested by the time we got to the RRHoF in Cleveland we covered every square inch of the place. I bought a nice refrigerator magnet for my wife, in case I had to tell her that we went to Cleveland! On a whim! The V-Tail has really interesting high AOA characteristics. It will land smoothly using an AOA that would make a Mooney float for a while before it abruptly stops flying. And a quick shout-out or two, one to Dr. Wolff who let me ride shotgun in his Eagle while he was knocking out a few IFR procedures for currency purposes. And, the other to Byron who rode shot gun with me in my O to KFDK where we met George at his new post.  Byron snapped my favorite picture of the year.  The one showing 2,000fpm on the VSI, care of the TopProp and 310hp. Last, but not least, Craig the Mooney pilot that started MS!

Some people are so giving.  I am glad you were able to take the time.  You guys are the best!

It is nice to see the memories have been preserved pretty well. Getting them back out used to be the bigger hurdle.

Next steps, proper capitalization with an outlook for IFR flight,

My apologies to Judge, the OP.

The stream of consciousness writing style may have caused some thread creep. See if I can help recover from the spiral...

Was that a Gill or Concorde battery?
