Williams flipper coil power level ratings are as follows
FL-11753 (yellow) Weakest
FL-11722 (green)
FL-11630 (red)
FL-15411 (orange)
FL-11629 (blue) Strongest strength
Please, can someone info us Stern Flipper coil power levels? my godzilla stern pin has strong flipper coils that hit inverted ramps from rear of the playfield with ease but my avengers infinity struggles to do the same despite setting the flipper power to max in settings and lowering the rear feet.
Godzilla pin has 090-5032-ND / 22-1080 coil on left and right coil is 090-5020-20-ND / 22-900 is this stronger?
Avengers infinity pin has 090-5032-ND / 22-1080 for both flippers

Short list I have on hand (stronger to weaker):

-----------OHMS WINDINGS GAUGE
090-5020---3.4-----0900-------22
090-5032---4.3-----1080-------22
090-5030---5.1-----1100-------23
090-5025---9.5-----1570-------24

Avengers should not be having problems with the stock coils. What's your playfield pitch? Have you checked the coil stops? If they're loose/broken it will rob power. Do the flippers lose power over time so you can't hit shots later in a game? If so, that's fade, and you just need to add a cooling kit.

Reply: Not sure which of those stern coils are the strongest you listed but Yeah, my coil covers look clean and game is home use only, rear feet are lowered the bubble in the level touches the bottom line, flipper parts feel tight, coil sleeve seems clean too. So perhaps it's coil fade because we play 6 balls to get through the Avengers story mode by collecting all 6 avengers 3 times and fighting for all 6 infinity gems, black order battle then 2 thanos battles. By the end the coils are so weak ball barely hits those shots needed to battle black order and thanos. Do you recommend any cooling kit?

Less windings stronger. More windings weaker.

Strongest on that list - 090-5020---3.4-----0900-------22

The list was strongest to weakest (I just added that for clarification).

What you're describing sounds like classic fade if the flippers are fine, then get progressively weaker the longer you play.

Inspect the area under your coils in the cabinet, just to rule out the stops being broken (not always obvious by looking at them). Is there gold "dust" in the cabinet below where the flippers are on the playfield? If so, that's a dead giveaway for bad coil stops.

If that's fine and no gold dust, it's likely just fade from what you describe. I have a kit for Sterns on the pinside store here and on pinmonk.com that stops coil fade by actively cooling the coils so they keep performing like they did when you started playing in any session. The kit is 2 flippers, but if you want to cover the 3rd flipper (not always needed) there's an add-on 1 flipper kit for avengers to cool that one, too.

Reply: You are a world of knowledge thank you my friend. I will inspect those stops and check out the website.

You happened to ask a question in an area I'm quite familiar with.

Happy to help.

reply: sold! I learned something new and you sold cooling a kit. win win. I'm a 10+ year tech so what you said made sense to me.

Awesome. You'll say goodbye to fade on your main flippers once the kit's installed. It really is kind of weird at first if you're used to it fading.
