Sega PSU extra harness

[erzane]

Hi there,

I wonder why a few AC/NAC do have four connectors wired instead of three.
On these pics, the 12 posi fourth connector is wired with several yellow wires (maybe some are +5v since they are yellow). What's their purpose ?

Also, there are some JVS NH connectors and also a blue AMP conn. hooked to this extra harness. Maybe these are for bigger systems like Sega Model 1-3 or others ?

Btw, I guess the cable clamp in the foreground (pink narrow) is only there to hook these extra harnesses ?

check the manual

you'll find 'em all
ex:

- It seems this metalic part is an ''ELE'' (what does it mean?) coin chute ? I thought it was a stereo amp... Why a 2nd coin meter ?
- Regarding the NH conn. I don't find anything in your manual.
- There is no 12 posi extra black conn with the yellow wires in your manual.

That many 5v lines on NH connectors seems like it would be for Model 2?
I think the model number I for that PSU is 400-5261-01X, which is basically a 400-5261 on top of a stereo amp, similar to the VS City power supply.

The blue connector, based on that snippet from the manual, seems to be for an ele(ctronic) coin chute (validator). I can't find any references outside the manual though.

Probably for the model 2 (or 3?) as you say.
By my side, I don't have the amp. but only the PSU (mine is 400-5198-01X).

Maybe do you have the manual of the model 2 or 3 ? I'd like to see what are these cables and how to connect them to the PSU.
