I have a new filter capacitor for my ASM and just want to verify leads first.

The current capacitor has a green/yellow wire and red/white/black wire going to it. There is a red dot on the terminal connecting the red/white/black wire. I believe that the red dot is used to denote the positive terminal but want to verify.

Can anyone confirm; red/white/black wire to positive terminal and green/yellow wire to negative terminal?

Thanks!

The green, with yellow stripe goes to the negative of the capacitor. Its marked wire # 54 in your diagram. The wire color chart shows 5=green/4=yellow. The other wire on the cap is #200 and that is Red with two black stripes. 2=Red/0=Black/0=Black. Does it make sence now?

Thanks, I didn't notice the 200 color code off to the right.

Gottlieb diagrams are very good and have alot of info.

I've got a few 25V 18000 mfd capacitors for bally and stern solenoid boards. Can I use that instead of the 25V 6800mfd?

I didnt know which way to install my replacement cap either, but i hadnt noticed the TINY -/+ on the new cap.

6800-12000uf is generally recommended. More than that is said to put too much strain on the bridge rectifier.

I just went with the recommended from the System 80 wiki.

"A very nice replacement for this capacitor, specified at 12,000uf, can be found:"

if you change both of the orange 6800uf 25v capacitors in a system 80a and put two 10.000 uf 25v is that ok or not

You can also take 1 15000uF/25V snap in style capacitor

so instead of 2 6800uf just put 1 15,000 uf /25v

Yes, it will do the job

Reaching out to the community for verification on a replacement. As long as the rating is correct — 12,000 mfd @ 40 volts, does the body style make a difference with the filtering application?

I have found a snap in “style” capacitor, which is physically smaller but the exact same rating, but much less in price. From what I have researched, these appear to be electrolytic (with polarity), and are used on printed circuit boards (PCB). This is comparison to the physically larger “computer grade” capacitor which is much more expensive. I need to get multiple capacitors, for a Gottlieb System 80A Caveman (2) and El Dorado City of Gold, so I am trying to save a little money. So would this “snap in” style work to replace the dreaded orange filter capacitor ?

Thanks for all your help and assistance. Thoughts?

It makes no difference here.

Rebooting this thread - I replaced the Orange Cap with a 10Kuf 35V and replaced the bridge rectifier. When I measure the DC voltage across the cap it is 13.5 VDC but when I read the AC voltage across the new cap it reads +29VAC.

Can anyone confirm this for me?
