Re: Asteroids losing voltage

You disable the sense circuit by shorting it to +5. The idea of it is to compensate for lost voltage over the wiring harness/edge connector. Its the same reason you see AR2's catch on fire when the edge connector isn't making good contact. The +sense and +5 are connected to each other on the game board, so the AR2 measures the voltage on the +sense to see if it is +5. If its not, it raises the +5 voltage. Unfortunately, it will keep raising the +5 voltage until things start to burn out. If the voltage regulator is shot, you won't get the +5 volts under load, but it doesn't seem to go out of control on the +sense either.

>Thanks Lewis. I ordered the parts a little while ago. But when you say "disable the sense circuit"... I know that the sense wire is basically used to check for proper voltage, but how do you disable? Are you saying to just disconnect it? And if so, could you explain why? (I'm not questioning you on being right, I'm just one of those people that feels like he has to understand why this does that or that does this. Personality disorder I suppose)Thanks, Dean
