Maybe we learned to do things better than what was done in the 1970's.

Study what we cleaned games with back then.

Turn em around when you can, but sometimes the wires just don't reach...

i tend to turn them around. but to be frank, on a Gottlieb running at 28 volts AC, it's really not an issue. Higher DC voltage where the flippers are stronger i can see doing it. but on a Gottlieb EM, the benefit is nearly null. so do what works given the wire lengths and your comfort level.

I think as a rule if it is home use, you can leave the flipper coil in the "traditional manufactured position" The coils were flipped in 1986-1987 after it was found out by
the street operators of the game High Speed that the diodes were busting from the coil tabs and causing erratic game operation and errors.
Wiliams industries would flip the coil and make new front coil brackets with a notch on the
top bracket to fit their flipper coils. 2nd generation front coil brackets would have two more notches add one on the lift and one on the right of the bracket.
High Speed would have a service bulletin that asked the operator to flip the flipper coil
by first cutting the coil key tab and installing said coil in "new" position.

At the Bally classes, they told us techs to reverse the flipper coils whenever you serviced them; even on older games.

If the wires are too short, cut a nylon zip tie with your diags to give you more slack.

Re-ziptie if you need to when done.
