Williams "Grande Prix" pinball made in 1976. Hey this is the year I graduated from high school! I was already repairing games on a game route for 2 years at that year. Maybe I took this one out of the box? This game has had it really easy after being retired to a home early on. The family just wanted it back in good working condition. No efforts to replace cosmetics and no paint touch-up. The repair notes below tell most of the story:
01/18/2017 17:46:15 Completed the mech panel on the bottom of the cabinet. Removed it to the bench, cleaned and adjusted everything, found 3 relays out of adjustment, lube motor and steppers, replace burnt coil. Completed all score reels, this is where most of your problems are so far, 2 wires off and 1 cold solder joint on reel coils, reel switches all messed up out of adjustment on 6 units, cleaned and lube all 20 units. Still have a few things in the backbox and the the whole bottom side of playfield yet to do. Game will be ready soon.

Both steppers on playfield were stuck, disassembled, cleaned and lube. Cleaned/adjusted all relays on the bottom of playfield. Repaired the chimes unit with new rubber grommets and a missing brass pin. Installed new front and back locks, same key on both. Replaced power cord plug, someone had a 2 prong, it needs a grounded plug. Found a 20 amp fuse instead of the 10 amp on the 110v line, replaced, this was dangerous. Checked all fuses. Replaced broken shooter rod with an identical from the period. Testing.
