Hey folks, just wondering if anyone has info on a jjp weak flipper.

It's the castle flipper. Upper left.

We had a coil lock on. Burning fuses and the coil was done. So I replaced the two transistors on the board correlating to the high and low voltage on that flipper. Then replaced the coil with an approved williams replacement.

Now we can flip the flipper bat but it is super weak.

Any suggestions? I verified continuity from the board connector to the coil on the hv line. Repinnes the connectors if they appeared worn. The coil was a brand new 11629.

The eos is normally open and verified it's not shorted at the switch.

Thanks for any help

Brian

IN test mode it would do the low voltage hold, and on the high voltage test it just hummed or did nothing. The flipper wouldn't move. I took a picture and wired the replacement coil the same. As the old coil. Different brands. Would it need the high voltage line wired to an outer lug? It's on the center lug right now.

I did not measure resistance or know what to look for with transistors. I swapped out with irl540n as tech support advised. What are normal parameters ? What makes the resistance.
