have a stern freefall with an alltek mpu and driver board in it, both are showing that they all work correctly. all voltages across all boards (driver, mpu, transformer/rectifier) are good but upon powering on the machine the mpu LED flashes the 7 times then when it goes to flash the 8th time and boot up it instantly starts kicking all the kicker coils (upper tramway kicker, multiball kicker, outhole kicker) and the game never boots up it just continuously kicks those 3 coils. anyone have any insight to what may be causing the machine from booting up? any and all help is appreciated. TIA!

It has all 3 in there, and the trough switches are good
