1st I am pretty new to this forum. I joined when I was in search of my 1st pin. I am super new in pinball machine ownership. I did find the machine of my dreams "PinBot" right from this site. When I tested the machine prior to purchase it worked flawlessly and over all is a very clean fine specimen from an era long gone. PinBot had to take a 2 1/2 hour truck ride which I padded the bed wrapped in furniture blankets and a tarp then gently secured with ratcheting straps. Got it home and in it's new spot fired it up let it go through it's warm up sequence. Well 1st thing I notice the lower pop bumper is a bit lazy as it took being struck with moderate force by ball to engage. No biggie I figured a little adjustment needed after the long trip. Well I am playing the $#!t out of my new toy all weekend and the pop bumper becomes completely dead. So I start researching how to remedy. I am also seeing a message on the alphanumeric display during warm up "bottom jet".So yesterday day 3 of ownership I notice a pronounced humming sound from the right flipper when button pressed or held in the up position. There seems to be no loss in strength but I notice arcing coming from the contactor at the flipper button. I can see it through a little slit by the ball launch. Knowing enough about electricity to get me in trouble I do know arcing is more than likely not a good sign especially with this new humming sound. Again I start a new path of research on flipper humming. So today as any newbie would do I fire up the machine just to see if it fixed itself lol. Well after warm up I hit the right flipper and yes it still arcs and hums and now it is stuck in the up position (and stays when I power down). So I pull the glass and raise the play field. When I work the plunger back and forth it definitely sticks in the solenoid at the end of the stroke. Then when I examine the paddle switch the primary contact comprised of 3 paddles contactors does not open because one of the paddles that is supposed to be attached to the second paddle (with contact) is broken and not allowing the contacts to separate. Also through manual manipulation and using the left flipper switch as a guide the secondary paddle is barely making contact when flipper is it the up position. I understand that second switch is vital for keeping power level if player holds flipper up to trap ball. I am mechanically inclined and knew the eventuality of pins being a matter of "when not if" repairs will be needed. I was hoping I would have had more time to enjoy my pin before crippling problems arose but it is what it is. I have to admit I am a bit intimidated by this situation and do not want to end up doing more damage trying to make a 1st time repair. I realize this topic has probably been discussed many, many times but any info and insight would be greatly appreciated.
Thanks in advance
