FuseUpgrade (resized).jpg

#1 4 years ago

Tonight I replaced the burned out left flipper coil and as soon as I started my first game, all of the playfield coils stopped working. (note all of the pf coils worked great before I replaced the flipper coil). I checked the fuses and F2 was blown. I don't have any replacements but before I go and buy a box of fuses can anybody suggest what may have caused it to blow after I replaced the flipper coil ?

Side note, the flippers still work but none of the other coils do.

Ok so don't hate me but I installed a larger fuse to see if I could figure out what was going on. Realized that after replacing the coil I waxed the playfield and when doing so got the left bumper upper contacts twisted together so it was keeping the bumper coil extended at all times (and BOY was it hot). Once I untwisted the switch contacts the game is playing great again. How I didn't notice the arm extended before I don't know.

Good work! Now make sure to get the right fuse and pop it in! Speaking of fuses, have you added the 8 amp slow blow fuses to the 2 backbox-mounted bridge rectifiers? That's a highly suggested modification that may save your game from catching on fire someday. Vid1900 has a good write-up on the procedure in his system 3-7 guide.

Congrats on the fix!

Quoted from FelixTCat:

contacts twisted together

By setting your ego aside, and reporting what you discovered, no matter how embarrassing it is -- you help dozens of people in the future who will wonder why a playfield solenoid fuse might blow.

thanks!

6 years in the Navy....... no such thing as letting ego get in the way anymore especially when it saves others from wasting their time trying to help me troubleshoot something like this.

This is how I did my fuse upgrade. Lined them up with the head bolts and left enough space to add the labels. There are more details on this update in the System 3-7 bulletproofing thread on pinside.
