I have a known working Rush the rock pcb for my 4th Rush the Rock.My old pcb wouldnt boot accept for the diagnostics ,steering wheel check,etc.So I'm checking the voltages befor I install the new one just because I dont want to screw up and the -5 was low at the board at 4.5 The 0.5 volts was getting lost between the plug from the power supply and the edge connector.So my question is could that being -4.5 instead of -5 be causing it not to boot.I was thinking about repinning the edge connector and the powersupply plug and trying it befor I plug my new board in just to see if that cures the problem.What do you guys think.Thanks...Dave
 
Repin the ps part of the edge connector and maybe go as far as to change out the power supply to be sure the correct current is being supplied.

+1 to Edge connector repining and cleaning, will do you good.
 
Actually the power supply side looks pretty good its the game side that looks not so great as well as the edge connector pin. But yah I'll probly replace them all and call it a day. Probly wouldnt hurt like you said to do the power supply, the power supply is putting out the corrct -5 like I said it just loses some going through the connectors. Thankyou....Dave....Oh but to my origonal question is -4.5 going to cause it not to reboot
 
Usually the -5 or the +12 being off won't cause issues, and it's usually being used for sound. The +5 is more critical.

IF the -5 is low though, it may suggest that the power supply isn't working properly in the first place, and may not be providing enough amperage on the +5v.
 
If you are losing voltage between the PSU and the board it means your wires are too thin, I guarantee it!
 
It is all origonal wiring and I did try another hard drive and it didnt fix it. If there are any gurus that would like to fix it for me so I have a spare please let me know maybe after the hollidays I could ship it out to ya.It would have all Rush roms though not Rush the rock.Ofcourse I would pay you a fair price to fix it unless someone just wants the challenge.
