ok after a day of playing here is where im at....
at the magnet driver board the yel/vio reads 78 v same with the blu so my guess thats ok as book says 50+
at the blu/wht 18 gauge at magnet driver plug i have no or very little power.. maybe 1v...
followed wire back to display board.... here i have 5v from the orn/yellow,5v from the blu/wht 22 gauge and 5v from the wht/brn/blk.
thought must be one of the q4 q5 q6 transistors as when i put a multimeter to them power was going through them all differently so changed all 3.
when i connect the magnet driver board same thing... magnet switches straight on!
any ideas what to test next?
