Something wired incorrectly , or something shorting it out making contact with it (another wire , glob of solder, maybe a screw that fell ) .Seems as though your problem is in your playfield somewhere .

Does it blow right away ? or do you get a couple flips then it blows ?

Bad coil? diode?
Swap with left one and see if problem follows.

Looks like a new coil in there . Did this problem start when that coil was put in ?

Back off trilogybeer! You trying to move in on my amazing swag?

Sorry , I think we are too late for the swag anyways . OH well , coil looks like the correct coil and appears to wired correctly . Maybe no diodes on the coil ?

Yes, its a new coil.

When you manually move the flipper all the way forward, how much gap is there on your EOS switch?

It needs to open 1/8" !

How many volts do you have at the coil?

Give us a clear rundown of exactly what is going on, because I can't follow.

The cab switch sparks, or the EOS switch?

The flipper tries to flip ?

Fuse blows if you hold the button, or just press it a few times?

Diodes have been checked?

Look at the pic of the left hand flipper coil that works. Looks like the wires going to his switch are coming from the center lug and the right hand lug of the coil.
Now look at the problem coil on the right.
Wires going to the switch come from the center lug and Left hand lug ( versus right on the coil that works). I don't have a game of this era to compare it to. But I'm guessing that coil is wired incorrectly.

Yes you are right , but it is the left side that is not correct it should be like the right .

Here's a pic of my Lost World flipper coils .

OK, in your last set of pics, it appears that you have it wired correctly. It was hard to judge on your first set of pics. Answer vid1900' s questions above and maybe we could offer more advice.

Yep wiring looks good now . What does the game do now ? I would hope that fuse protected your board from damage . That wiring may have been your only problem but could have caused more .

I think he had it wired right to begin with. I think it was an optical illusion caused by the poor quality of his original pics that made me think that one wire was attached to the wrong lug.
Either way, OP needs to give us the rest of the story here.

Yeah you might be right , it may have been an illusion in that first pic. He did change a few wires on the new coil going to EOS basically reversing the way electricity would flow through it. It matches mine now but I don't think it matters which way it flows through the EOS no diode there it is on the coil.

Make sure your cabinet ground braid is not contacting the flipper switch anywhere . Inspect the wiring coming from the coin door . Those get kinked and damaged and can cause some goofy problems.

Did the game always have this issue since you've owned it?
If not, what sort of repairs/adjustments were you doing just previous to what is going on now?

I still think you have a bad coil or the diode is bad or installed backwards.
Have you swapped theft and right coils to see if the problem follows that coil?

Good then you'll know if it is good or not, good to eliminate possible causes puts you closer to a solution. I still think your problem is in the wiring somewhere , wish I could see the game in person I could probably be of more help then.

Excallent news!

If you would have just listened to me a week and a half ago...
Seriously, glad it's fixed!
I'll be standing by my mailbox waiting for my swag.
