Hello pinheads!!
I purchased a doodlebug (love love how hard this game is) and to my knowledge it worked fine before i cleaned the top playfield and re-rubbered the machine. Now the game works but it doesnt doodle.
The centre switch (that activates the magnet) clicks (relay) when hit and the ‘stop doodle’ switches also release the relay.
I am not an EM guy, and I'm struggling and fear touching anything as i know the challenges if something is out of alignment. I checked all the switches above and below the playfield nothing is stuck closed when I re rubbered.
I would be willing to donate $20 to pinside for some resolution.

The doodlebug relay activates when the centre target is hit.

When you activate the stop switch the stop relay activates and the doodlebug relay releases

I have read something about the pulse relay being connected to this, but i do not see it activating.

The ohms to the magnet (game off and meter on each side of the magnet measure .51)

When i have the game on and the magnet is ‘off’ the dc volts measure 5.4. When i activate the magnet via the centre button it measures 55v

Is this ‘the Zach’ ?!? From slam tilt?!

WOW!! Mark and ZACK!! I am in pinball nerd awwww!!

Ok I had to go to work so I will check this all out after work. thank you guys so much for the info.

Mark that Diagram is amazing thank you. never knew of your website, looking forward to poking around there.

is that why with the game off, but still plugged in I got a good zap when I touched the pulser coil while holding onto the side rail? that woke me up!

my bad... I knew that, but was trying to rush before work. I will re check tonight.

Yes I shoulda noted that in first post. Fuse is good and the holder is nice and snug

thanks again guys!!

nothing. the rollover switch activates (and chimes) but no magnet function.

So, should I have continuity with this magnet? Or is it not measurable because the wiring of the magnet has a coating on it?

SOLVED!!!
Thanks guys! I will update in a little… just gonna drink a beer and enjoy this feeling of doodlebug working

Ok…. So the key was checking the continuity to the magnet. We noticed there wasn’t any.

For some reason there is a break in the wire on the one side to the magnet. It was covered in wlectrical tape but not soldered. My friend said even thou it looks connected it isnt. He sanded the wires and soldered them together. BOOM.

Thank you PINSIDE and Garth!! Doodlebug is back to frustrating me as a player and not a somewhat tech.
