Rewiring an afterburner that had bits of the loom removed, chopped off and the transformer has been changed so standard Sega colours in the manual no longer apply. Specifically looking for the wiring for bridge rectifier and amp power board. The amp power board has five connectors 3 in two out the three in are listed AC CT AC, I presume the ACs in are from the transformer but I don't seem to have a center tap on the loom so no idea what iam missing the output is 12v and Gnd going to the amp which is fine but the 12v has another cable coming off it, not sure what it powers? The relays? Also the relays are fused but no wires so pin out would be handy iam guessing these follow standard wiring colours per the manual but both blue and white wires are through fuse blocks so what voltages are these? Ia few pics around the bridge recitifyer/capacitor and the power board for the amp would be handy if anyone had them. Thanks

Thanks a mill mate that really helps, I'll have to measure voltage from the transformer as it's been changed at some stage and seems to be missing a center tap. Also the wiring on the relays are different colours so trying to determine what voltage they take on what lines

struggling to upload photos today for some reason, everything really slow, keeps uploading previouse image
seemed a weird setup to me as you have center taped 15v 0v 15v from Transforner (Orange Wires) to the pcb thats broken, then I think that has 12v that powers the amp

No promblem, you'd think this is where the manual would help but mostly a waste of time, colours I'm sure are different on USA ones, should have some pics of the upright UK cab somewhere, might take time to find them but I'll see what I have and upload some when I can

I think that 15v is stepped down to 12v by the amps pwer supply next to it, but that red/blue from 12v on amp in the right of your pic goes somewhere else so something else is getting 12v. relay maybe?

Yeah the manual colours are completely different and all the connectors have been either removed or chopped off so rebuilding it blind!
