Found a d9 6.2v zener diode at a local shop checking tonight. Whats the best version of a pac edge connector fix? Jammaboards seemes to be closed atm |

the edge conector (i use) is a modified normal jamma connector.. i did look your table over i do not find faults to chat about a ohm here or there , ah age/stress (your hair goes grey to believe it or not) a volt here or there ? thats a little much but .05 eh not worth the grey hair... if the zener is bad there is olny a few ways normal is dead short second is leak third is open so in short unless u have seen little grey smoke fairys ? and or your board will not even power up u are reading it in circuit (bad) normal test (unsolder 1 end lift out of board) read if good ? put end back in carry on if open u will see 5.2 volts go to the full rail voltage of the feed (ie 5.2 would =12) like that if leaky? well then that is open ed |

Also check out this AMAZING guide about pac boards. Apparently this guy worked at Midway (cool story about Crazy Otto and Ms. Pacman too - Great read). http://lawnmowerman.rotheblog.com/#settings DeL |
