Adam Godfrey details restoring a 1976 Williams Grand Prix EM, covering mechanics and repair lessons.
Grand Prix is one of the more complicated EMs due to the late-model design with many steppers and relays
high confidence · Nick Baldridge and Adam Godfrey discussing Grand Prix complexity relative to other EMs
Grand Prix had 10,554 confirmed units produced, making it a high-production EM
high confidence · Adam Godfrey citing production numbers, stating this is why the machine has been worked on frequently
The bonus counters (steppers) on Grand Prix are positioned dangerously close to the front playfield, making them easy to damage during playfield removal
high confidence · Nick Baldridge's experience working on multiple Grand Prix machines
EM repair fundamentals boil down to cleaning switch contacts and adjusting switches
high confidence · Adam Godfrey's takeaway after completing Grand Prix restoration
Adam's Grand Prix has a one-way orbit gate that will cause a tilt if the plunged ball hits the left-hand spinner first
medium confidence · Nick Baldridge cautioning Adam about playfield modifications
Adam is on a one-year buying freeze (through August 2025) and plans to acquire Teacher's Pet next
high confidence · Adam Godfrey discussing his acquisition roadmap with wife's approval
“I will talk pinball every day, all day long if I could. I'm still trying to figure out a way to make money off of it instead of lose money.”
Adam Godfrey @ early segment — Captures the hobbyist's passion and financial trade-off inherent in pinball collecting
“Once you look at a schematic, and even then you don't necessarily have to learn how to read a schematic, but it's great because all it is is just switches. It's just a ton of switches and relays, which are just stacks of switches, controlled by the solenoid.”
Adam Godfrey @ mid segment — Demystifies EM repair for solid-state technicians; emphasizes fundamentals over complexity
“Be careful how you lift the playfield, because aside from the steppers that are right at face level, there's also all those relays which are easy to clip if you lift at an odd angle or do something funny.”
Nick Baldridge @ late segment — Critical maintenance warning about Grand Prix-specific hazards during service
“I love it because I feel like I'm doing much better than I probably am because the scoring on that game is like ridiculous. It's so easy to roll it over.”
Adam Godfrey @ mid segment — Highlights Grand Prix's forgiving scoring system and appeal for casual/new players
“It's the only thing I have yet to figure out, and it's just going to take time for me to sit down... there was something funky going on with the 500 point relay.”
Adam Godfrey @ mid-late segment — Documents remaining troubleshooting work and use of community resources (Grand Prix Owners Club thread)
restoration_signal: Adam discusses polishing stepper unit contacts using Scotch-Brite pads and applying Super Lube; Nick validates this as Zen-like and effective; emphasizes importance of careful playfield handling to avoid damaging bonus counter steppers
high · Detailed discussion of stepper disassembly, polishing, and reassembly process; Nick's warning about stepper proximity to playfield edge
product_concern: Grand Prix has a structural design flaw: bonus counter steppers positioned dangerously close to front playfield edge, making them easy to damage during service; also has hard-to-reach relay stack in back of playfield
high · Nick Baldridge: 'the bonus counters, which are steppers underneath the playfield... it's really pretty trivially easy to damage those... they're pretty close to the front' and 'you have to lift, like, straight up for a good foot or 10 inches'
restoration_signal: Adam experimented with isopropyl alcohol (91%) and magic erasers to clean playfield, removing clear coat in process; followed Ryan Claytor's advice to wax heavily instead of re-coating; no wear observed after months of play
high · Adam: 'I experimented with the isopropyl alcohol, 91% isopropyl alcohol... It worked. It's magic. Now, I do know that I have removed the clear coat from my playfield'
product_concern: Grand Prix's 500-point relay (on right/left kick-out holes) is malfunctioning; relay actuates but doesn't release; Adam has disconnected feature temporarily; root cause unclear but likely electrical or magnetization issue requiring further diagnosis
high · Adam: 'there was something funky going on with the 500 point relay that I have not... been able to identify' and 'For some reason it actuates, but then it doesn't release'

design_philosophy: Nick and Adam challenge the perception that EM repair is intimidating; core skills are switch contact polishing and adjustment; fundamentals apply across all EM types (ball bowlers, puck bowlers, bingos); encourages solid-state technicians to engage with EMs
high · Adam: 'all it is is just switches... if you get really good at like... polishing switch contacts and adjusting switches... you can fix an EM'
gameplay_signal: Grand Prix features high-scoring potential via easy bonus rollover and collector, two spinners with one-way orbit gates, drop targets, pop bumpers, and kick-out holes; bonus select feature randomizes which side pays at drain; open-ended in-lanes create ball-dump risk when trapping
high · Detailed playfield descriptions: 'two spinners one on each side, orbit, one-way orbit... bonus collect... kick out hole' with 'four drop targets, three pop bumpers, two spinners'
community_signal: Adam documenting full restoration on Pinside forum thread 'Start Your Engines: Williams Grand Prix Project'; community provides troubleshooting support via Grand Prix Owners Club thread; demonstrates active knowledge-sharing culture
high · Adam: 'I have a thread on Pinside that documented my trials and tribulations' and 'I posted this problem to the Grand Prix Owners Club thread'
product_strategy: Adam implementing 12-month buying freeze (through August 2025) agreed with spouse; planned acquisition sequence: Teacher's Pet (priority) and Ding Dong (secondary); seeks both machines but plans to keep only Teacher's Pet long-term
high · Adam: 'my wife and I put me on a buying freeze for a year. So come August 2025, Teacher's Pet is mine' and 'I'm going to get both of them, fix both of them up, and then find a home for Ding Dong'
gameplay_signal: Grand Prix appeals strongly to casual/family players due to forgiving scoring (easy rollover potential), loud chime box, slower playfield (low incline), and spinner feedback; kids attracted by sound and mechanical action; good entry point for younger players
high · Adam: 'kids have loved it because of the bells... super loud... even as fast as it is, it's still a lot slower than the other games' and 'there's so far the children like it'
manufacturing_signal: Grand Prix was a high-volume production EM with 10,554 confirmed units; this volume explains why Nick has worked on more Grand Prix machines than any other single title
high · Adam: 'There was 10,554 confirmed units... That's a good number. They sold a lot.'
restoration_signal: Adam refurbished vintage chime box from Gulfstream machine: replaced coil sleeves, added new rubber gaskets, tuned system for crisp ping; installed in Grand Prix as upgrade from basement-stored unit's original components
high · Adam: 'I refurbished a chime box off of a Gulfstream and got everything tuned up, put new sleeves on the coils, and I put new rubber gaskets... so it was very, very crisp ping on the chimes'
personnel_signal: Ryan Claytor identified as trusted EM restoration authority; provided playfield maintenance guidance (waxing over clear-coating) that Adam adopted successfully
medium · Adam: 'This came from... Ryan Claytor. He says, and this is a man I trust, mind you. He said, don't worry about it. Just wax the heck out of it'
