Remove that ASAP!! Solder a new battery holder to your board and install 3 AA lithium batteries. Replace every ten years after that.
Eugene, OR
Not sure on the batt, but if it was my machine I just put it back to stock or do a remote battery box.
This is what I used on my No Fear:

Quoted from GRUMPY:Remove that ASAP!! Solder a new battery holder to your board and install 3 AA lithium batteries. Replace every ten years after that.
Please don't solder back a new holder back on the board.....
Install a remote battery holder. Your good to go, solder to the two points and call it a day. Takes maybe 5-10 minutes.
Whether you reinstall a battery holder on this board or a remote holder, make sure they didn't remove the blocking diode from the CPU.
Quoted from schudel5:Whether you reinstall a battery holder on this board or a remote holder, make sure they didn't remove the blocking diode from the CPU.
Due to installing not rechargeable batteries right? Is there any easy way to see if the blocking diode have been removed?
That battery holder pcb is stock, it was used on some pins. The GenRad sticker is from where the pinball manufacturer tested the board on their #6 GenRad machine for Quality control and functionality.
I used to work on a GenRad that had the hard drive in a pullout drawer. The hard drive itself was the size of a large microwave oven. It was way old and way obsolete back then.
Quoted from webdiddy:Thank you. Out of curiosity what can happen if the resistor is not replaced? Exploading batteries?
Yep. You'll be trying to recharge batteries that aren't meant to be charged. The batteries will, more than likely, explode causing more issues.
I would just run without batteries until you get a diode. Yeah it's a pain losing settings and adjustments.
I know some that have replaced that diode with a standard 1N4001. I'm not saying that's what you should do, I'm just pointing out what some have done. Not sure if that's a good idea based on the specs of a 1N4148 vs. 1N4001.
Quoted from webdiddy:...and I think it looks factory.
Get your eyes checked after you replace the battery pack 
Quoted from Crash:What is the diode orientation? Very important.
Also, upgrade that game ROM. Looks like it's got 1.1 in it.
Some major improvements from 1.1 to 2.0 relating to how the magnets on the ramp operate if the opto switches get broken. The ramp can melt from the heat of a locked on magnet coil, and a lot of NFs suffered major damage from this.
2.3 is the latest.
If you can't source one locally, I can ship one to you. I would also throw in a couple 1n4148s if you need them.
Quoted from gutz:Get your eyes checked after you replace the battery pack
Yes, I know what battery packs they normally use but the install was really clean looking and made me think this was maybe a factory special or something.

Thanks for your offer! I think I can find the rom locally and the diode will be purchased tomorrow.
I took the board out to desolder the resistor, it turns out that the diode was still there underneth (see picture). So I just used my sidecutters and snipped the the resistor off, no need to resolder a new diode right?

Anyway, I still can't get the battery pack to work, I must be doing something wrong. Please take a look at the pictures and let me know what I might done wrong.
Thanks.
