Flipper diodes

[M4carp]

Just noticed on my RS the lower and middle left flipper has a diode missing, never had a problem until I swopped the power board for another now it resets with left flipper.
Would this cause a reset?
And is it a 4004 diode like on the micro switches as I have a few of them.
Thanks

The Fliptronic II pcb has additional tie-back diodes for each flipper winding, so it shouldn't cause a problem if the coils themselves lose their diodes. The diodes used, AIR, are IN 4004 (with a higher reverse-voltage rating, or 'PIV', than 4001's)
