so i'm going to NL again tomorrow for work, and my boss has invited me over to dinner at his place on Tuesday night. i've been before, he's a nice bloke and has two tweenage sons, and last time we drank beer and played on his Shadow.
trouble is, this time he mentioned can i bring a few tools with me and show him how to diagnose and fix a couple of problems on it. yaaaaaaaaarrrrgggghhhhh! i'm hopeless at anything like that. i already told him i can only try my best and he said that's fine, but of course (being my boss) i want to impress him by doing the fix.
so my question is - please can you clever lot explain to me in simple terms what to do and how to try to fix these two issues he told me about- 1) sometimes 2 balls in the launcher lane; and 2) ball doesn't get kicked up to the battlefield.
all i can think of for starters is this: check correct number of balls to start; put in switch mode (i never got what the difference is between 'switch edges' and 'switch something else') - and see if i can work out if the balls are triggering the sensors (?microswitch ?opto) in the trough and in the shooter lane and in the battlefield VUK, or not; see if i can make that coil fire in test menu; look for a wire off the coil that fires the ball up to the battlefield; look for anything else obvious, like a snapped bit of the VUK coil mech, or the plunger is catching in the sleeve; look for popped fuses; take some spare new balls in case magnetised balls was causing the double launch.
i'm sure i'm missing loads. what if it's something on the board, like a transistor? what do i do in what order?
and what tools do i take?
help please fellas.
