[QUOTE="Mayuh, post: 72716, member: 1152"] You got a bargain! I've never seen table from that time being so clean under the playfield. From what I've seen, your EOS switches (the long copper ones) on your flipper assemblies are corroded. That means the current has a hard time getting to the coils (which don't have to be replace usually, as they do not wear - but check if the correct ones are installed! I can't read the badge on them from your photos...). Just spent $30 on a rebuild kit and you'll be happy (i found this, so you know what i mean: [url]http://www.pinballlife.com/index.php?p=catalog&parent=172&pg=1[/url]) Take photos before the disassembly :) and then tighten the screws as hard as you can, without ruining them. It's really easy to learn how to make the flippers work again. One trick here to get strong flippers is that the EOS switch has to open its contact at the latest possible moment. The coils are actually two coils: one for the power (which is driven by the current it gets when you press the button) and the hold coil. If it the EOS opens too early the power coil can't develop its full strength as it is switched off to early. [url]http://www.pinballlife.com/index.php?p=catalog&mode=search&search_in=all&search_str=Firepower[/url] I'd replace all fuses - they are cheap. I really can't tell by your photos, but for me it looks like the upper fuse is blown on your soundboard. Also check if there are any signs of corrosion on the fuse holders. On a side note, you won't really need some DMM to measure the amps, all you need from a multimeter is its function that beeps :) to check if the contacts are ok... Have fun and enjoy! [/QUOTE]
