I have a really hard time sacrificing yet another *IstD or *IstDL for its organs.
Luckily they each have 2 solenoids so I'm sparing a extra lesser body it's life !
The recipient is a K-S2 that was made in 2017 serial # 733xxxx.
You may read about the later K-S2's being made were somewhat less likely to develop ABF as Pentax possibly did some change to the solenoid ?
Rest assured....They aren't as evidenced by this one that is acting up since friday.
Started only in Live View and now is doing it more often using the view finder.
Luckily this will be my 4th repair of a solenoid on various defective models , so all should go ok.
My incoming donor ..... oh my.....is nice.... Very nice !
I almost feel guilty. Hope I can do this and sacrifice it quickly.

The Victim...hmmm... I mean "Donor" is incoming from Ebay on Monday!

Dear God please forgive me for the body life i'm about to end. I promise to breathe new life into another 2 bodies in greater need.....Amen.

We know a man from the far south west
Who could fix ABFs when put to the test.
But said he with a scowl
As he threw in the towel
This brand, my dear boy, I really detest.

Haha ! Very Good .
Kinda reminds me of someone I know as of late....

Or in this case....Death feeds on Life....lol

I'm really feeling bad now.
Seller sent me a nice email hoping I would enjoy it as much as he did.

I couldn't help myself.....Responded back that I most certainly would ! Possibly even 2X as much !
Oh my........

Ron, I'm so impressed with the way you're approaching a very unfortunate set of occurrences. Laugh instead of cry, how refreshing. Best of luck with those K-S2's, they were some of my all-time favorite cameras, The last of my four last finally sold a little more than a year ago, and thank goodness I never had the issues with any I owned that you've had with yours.

Keep us up-to-date will ya?

It is not quite like that.

If you read This post concerning the history of the solenoid in Pentax cameras you will see I added recently some further information.
I had a few K-70's and a K-S2 manufactured in 2016 for repair. As I noticed a small but significant difference of a China Solenoid sold by a Ricoh
repairshop in UK I purchased one as well to find out and there is an important difference.
Any, I still see the white Japan DSLR solenoid as the very best solution.

I wouldn't say I'm laughing quite yet. I envy people that have never had ABF on the usual suspect bodies. I'm now 3 for 3.
I'm not short on camera bodies by any means , but I use my K-S2's daily and dearly love them.
My beater K-S2 has already been given the appropriate transplant about a year ago and never missed a beat since. 50K clicks now.
This K-S2 was one of the very last ones made. Supposedly largely immune from ABF....Yet here it is again at 3K clicks.
I'm very stressed and aggravated , but what else can I do ? May as well have some fun with the situation...

I assumed by my cameras manufacture date and later serial number that it has the second modification ?
But since it is failing something is still wrong.
I have done a few solenoid repairs and wouldn't think of putting anything in except for the white original.
Will keep you posted on the transplant , and identifying which version it currently has.

That will be interesting and then we know more!

I myself wouldn't consider anything else than the white original solenoid as well, but I'm a perfectionist and usually don't like half-baked solutions.

I had a car that required a few taps with a metal hammer on the starter motor solenoid now and then for the starter motor to fire up ..........
Ummmm, sorry - not on topic???

My 70 Cutlass. Always had the hammer in the car. I thought about trying it on the ks-2. You can't reach the solenoid without disassembly.
Speaking of reaching the solenoid, I also learned never to park where a puddle might form in case it rains.

But we will eventually run out of the white ones.
Hopefully Pentax will have figured it out by then and the solenoid will no longer be the ‘weak link’ in K-n0 camera bodies.

71 GMC for me. at least with a pickup it was easy to swing under there and smack it.

Solenoids tend to be very simple electromechanical devices and their mode of failure is consistent: the insulation between the coils, some number of micrometers in thickness, simply shorts out and renders the device "no worky". In the 1950s and 60's my grandfather had a repair shop that rewired armatures of various kinds, usually for generators and alternators of automobiles, but sometimes also the odd appliance. The tooling nor the process is not complicated, and these days you can order fresh wire that's already been uniformly insulated to tight tolerances, unlike the dangerously hot shellacking my forebearers, including my child father, gleefully performed by hand without respirators.

Perhaps there are a couple mechanical engineers on this site that would be interested in designing simple tooling for a rewinding apparatus that could be 3D printed. If such a device were powered by hand crank from a commonly sourced worm gear (McCaster-Carr has a decent selection) it would slow the winding process down to permit visual inspection of the coil pack as it's being wound back on, and 2) be easily reversible to correct any problem with a spool feeder or the rate of slide of the solenoid core after being set into the jig. I was looking at photos on this site of the solenoid in question, and it doesn't seem like it's particularly small nor complicated to rebuild. Not everything needs to be manufactured in mass quantity to be both reliable and good.
