Here are the pics for the two ramp coils. There's not really a "hold" coil. One coil fires ramp up into lock position and the smaller coil unlocks it to drop.
I suspect someone may have replaced a coil on your game that had a resistor on it. If either of these coils has one bridging the lugs you need to cut it off. It will short out the coil and cause bigger problems.
The green labeled coil is the up coil, the other (yellow) coil is down.
