Jurassic Park Flippers - pushing rather than smacking the heck out of the ball

[ScottoKong]

Hi All

After the talented Mr Beaky got my boards all sorted my JP is up and running.

Has been really playable up until the last week or so.

As in my description the flippers - now both left and right don't feel 100% - or the usual 150% that DE flippers feel!!!

I've cleaned contacts and made sure the EOS isn't engaging until the last 1/16th of the action.

Shots on the tip of the flipper just get pushed and the flipper doesn't get past horizontal.

About to place an order for some new EOS leafs, but does this potentially sound like a flipper board issue?

Any advice welcome.

Were the fuse clips replaced? Is a must do in ALL D.E boards.

With power off gently press on the centre of the fuse on the flipper board (left side of lower cab). If the fuse clip gives way time to replace.  Check EOS as well on flippers

Thanks Marty - I went and gave the fuse a little push.

F4 is rooted - gave way like butter.

I'll be talking to Beaky tomorrow.
Would my TFTC flipper board drop in OK for testing???

Don't know off the top of my head. You may have to check the manuals for part numbers. Either way fuse clips are a MUST before any other fault finding

[beaky]

all faulty fuse clips were replaced on the boards that were sent to me.
As Marty said this is a necessity. after the clips are replaced then you can check for further problems.

 in some instances faulty fuses can cause problems also, especially when there has been faulty fuse clips replaced (fuses can run hot due to the bad connection to the fuse clip and damage the connection between the fuse ends and fuse wire inside the fuse) so if you are unsure replace the fuses.

After you have sorted the electrical side of things you will want to make sure that the flipper coils are held tight in place, you don't want your coils moving around.
also check that there is minimal moment in the flipper linkage between the pawl and shaft ( you will lose power / energy through excessive wear on any linkage / plunger on any solenoid in your machines)

also check that the flipper is not dragging on the playfield due to excessive wear in the flipper bush or the flipper is not to tight in the bush. (it should have some movement when you pull on the flipper)

make sure all the connections in the wiring to the flipper board is fine

Thanks for the input guys.

I didn't think to send u that board Andrew.
Might have a crack at changing those clips myself. Don't look too officially a job.

Just take your time and be careful not to lift tracks when removing, but essentially is a DIY job.  The 3AG fuse clips are available at Jaycar for a few dollars.
Ensure the correct value fuse goes back in.

I've managed to replace the buggered clip on the flipper board.
You haven't got competition Beaky, I'll be keeping my day job for now.
For once a 5 minute repair actually took 5 minutes!

It was for the 9v hold fuse and feels like everything has toughened up.

Still get an occasional bunt from the right flipper but I'm hitting heaps more ramps and solidly hitting the top lock.
Going to check the EOS later tonight.

Thanks again guys.

well done, glad it went to plan

I'm on a roll now!

Today I've replaced a diode (D25) on my TFTC that was preventing adjustments from being saved.
