Pole Position 5v and Ground jumper wire mod clarification, advice need - Daisy Chain?

So, I am planning on doing that 5v and ground jumper wire tonight to my Pole Position.

I have seen it done a few ways and the biggest question I have is, should I daisy chain the wires?

I was going to run one single red wire from the +5Vdc from the AR to one of the +5 lugs on the PCB. Then run a wire from that lug to the next +5 lug, etc. etc. until they are all connected to each other. And do the same for the ground (running from a ground lug on the AR to the first ground lug in my chain on the PCB). Is this ok?

I picked up 18 Gauge wire to do this. I will install a 2 pin molex between the AR and the first two connections (+5 and Ground).

Am I understanding the proper way to do this?

Thanks!

It's OK, but overkill. You just need to bypass the edge connector. Jump the ground and +5 from the ARII to the ground and +5 lugs on the PCBs. Connecting to one lug on the PCB is all that is necessary. On mine, I did not have +5 lugs on the ARIIs, so you will need to find a good place to tap the +5. I used one leg of the resistor that sticks above the heat sink. Also, make sure you jumper each ARII to the same PCB that is being fed through the edge connector, or you'll have regulation trouble.
 
I don't follow this part. Can you please explain? Thanks!
In the stock configuration, one ARII provides power to the CPU PCB, and the other ARII provides power to the video PCB. You're going to jumper one ARII to the CPU PCB and the other one to the video PCB. Just make sure you don't cross them, since the ARIIs rely on feedback from the board to maintain regulation. Does that make sense?

That makes perfect sense. And, wow, I had no idea there were two ARs in this game. I guess I have much to learn about PP. :D
 
I was gonna do the mod tonight but saw that my board had a bad/cracked/broken CR2 on the CPU board after I pulled it out. Did some research and found out this was a vital part to the power section so I'll wait 'til I do the mod on my main board (after I replace the 1N4735A).

So.. I grabbed a board I just picked up that supposedly worked and stuck it in (without doing the mod) and it almost worked. The cars had lines through them. This board had some edge connector work already done to it. So, I did the mod and did end up daisy chaining a few of the lugs and tapped into the +5 and ground near each edge connector. It fixed the graphic issues with the board and seems to be a success.

However I am noticing an odd very minor glitch during high score entry. You can hear some faint sounds during entry and also some very subtle lines moving. Not a huge deal but not perfect. I'll fix my original board with the CR2 and do the voltage mod on that next since I know the history with my board.

Anyways, thanks for the help. I feel like I understand this much more after tonight.

Did your ARs have lugs for the ground and +5 both? Mine only had ground, but I've heard that different versions of the board had different test points.

I've been meaning to shoot a short video of my power and fan mods. Maybe this thread will be the motivation I've been looking for!

I ended up not tapping into the ARs. But I didn't notice any lugs. So, I just tapped into the wires right behind the plastic edge connector.
