Rookie owner seeks advice.

I have owned The Addams Family game for a month now, facing my second repair and first on flippers. I have no previous experience so please bear with me if I am asking stupid questions.

My right flipper suddenly went very weak. When I hold the flipper button and it is up, it is as strong as the other. But if I add resistance in the stroke it just retreats with the weight of the ball.

I read the basic sections of VIDS guide to upgrade flippers and some additional sections and checked the potential culprits. I found the plunger, coil sleeve, coil stop and EOS switch almost brand new, which I guess rules them out? The EOS makes contact just before end of stroke, similar to the left, and I guess that is ok too? What I DID find was some sewere play (rocking 2-3 mm) in the flipper and given the fact that it is strong in end position, I conclude the blame lies on the flipper bushing and I just put in basket to order new ones.

My main question now is: Can I expect adding new flipper bushing solves the problem or is there something else I should check (coil or...)?

Thank you in advance to all friendly people in here.

Do you have a broken wire at one of the flipper coil lugs where the wires are soldeted? Tug on them a bit since the wire may apoear not to be broken away.

I tried a bit of tugging, but the solderings seemed perfect. But thanks for the advice.

Then your bushing likely will be the issue.

The wires going to the coil can be fine, and soldered on "perfect", but the reddish coil wire itself can be flakey or broken, and still look ok until picked at a bit. But use care when doing so, too much can break the thin winding in particular.

Have you metered all the fuses in the fliptronics board in the head?

Sounds to me like the hold side of the coil is working and your missing the power side. Make sure eos are adjusted properly.....make sure cabinet switch is in good condition and adjusted properly...... if those all check out, I'd change the coil. Tough to say without being there, but that's my guess.

Disassembling and replacing the flippers under the playfiled the first time seems/feels like a scary task, but after you do it once you'll be a pro.
First thing I'd do is pull your pf up to working position, grab an allen wrench and disassemble the flipper mechanism. Once you do that, there is a plastic sleeve that sits in the coil. It should flow out from inside that coil easily. If it does not, you probably need a new coil (these coils last of pretty long time, but in these older machines, It's not unusual to have to replace them, and they're not that expensive). If you look at the coil, it will have a specific number printed on it, and most pinball companies online will have a replacement for you. Additionally, these same companies will have flipper replacement packs specific to your era of machine. These packs will replace all the pieces including a new coil sleeve. Additionally, the small piece of metal that has a round piece in the middle of it, the coil stop, is probably flattened. These packs will have everything you would need, including a new coil stop.
The first time you do it, it may take 30 minutes, but then you'll be a pro and it'll take a little bit less than next time.
Based on the age of your machine, I'm just guessing that the flipper mechs probably never been replaced /repaired, and a new setup will probably bring your flippers back to life!

Thank you all for great advices. I now tried switching the coils, and along with that switching the weak flipper to the left one, ruling out any mechanical problem (I change the bushings anyway, since there is to much play @pinballmaniac40 ).

Also all mechanical parts looks brand new, since coil sleeve is clean and both coil stop and plunger are in mint condition. So I am going to look at electrical troubleshooting. Thank you for your support @chipscott - it IS a bit scary this first time, but thanks to help from you guys and great guides from VID I am growing more comfortable.

It is late in Denmark now, But I definately will look into next steps:

Well, I looked at te Fliptronic board and it seems I found the source to my flipper problems. since I am new to this and my skills are mostly mechanical, I am interested to hear you guys out whether Q9 is likely to be the mother of my flipper problems?

Q3 and Q9 seems to be replaced in the past. Both are for the LowerLeftFlipper.

Q11+(Q12+Q4) are for the LowerRightFlipper.

Ah ok, I see. So basicly it doesn't explain my problem? I no doubt Q9 needs to be replaced anyway. But would you say I should look at coil for further investigation?

The coil could be the problem.

With a multimeter you can measure resistance of the 2 windings (with machine OFF)
If the hi-power winding has about 5 ohm, transistor Q4 on the fliptronic is next to test.

Thanks, it is really helpfull. I will do so when over a busy period at work (up to x-mas).

Well, problem solved. I cabled high power to ground, and it fired. Then I did the same with the socket at the fliptronics board... and it Fired. Then i put the socket back and.... it all worked again.

A bit embarrasing for me, but I learned a lot on electric troubleshooting

Thanks for all your help
