ALL VOLTAGE CORRECT REST OF GAME OPERATES FINE,
ANY IDEAS GUYS THANKS

This should be pretty easy.
Does the flipper enable relay pull in when the machine boots? (it is the relay near the top left of the solenoid driver board). If it does, look carefully at the contact INSIDE the relay, these frizzle and are a common source of flipper problems.
The circuit is pretty simple:
B+ is ALWAYS applied to one side of the flipper coils so you can measure this with reference to ground (+48V or around that - not critical, as long as it is there)
Check the flipper enable relay pulls in and that the contacts inside the relay are sound
Check the connectors and wiring as shown in the part of the wiring diagram below.
Play a game.... #*#

In addition to Mike's advice, Look at the playfield fuse. You need to look under the playfiield, near the front. I think for 3 flipper games it is a 1.5 A SloBlo - Check with the manual to be sure.

hey waz it may be the Q19 i think or try reseating cpu connectors ^^^

+1, in particular J4 on the cpu. Could also be J4 on the solenoid driver board having tarnished pins on the board or connector
Q15 on the solenoid driver drives the flipper relay (can be seen in pic in Homepin's post), you could try grounding its metal tab to the aluminium ground shield in the backbox with a test lead, to see if the relay clicks in.
