Cruis'n USA Resetting

[480G]

Hey y'all!

I have two crusi'n USA cabs in my arcade. About a week ago the one on the left started randomly resetting. I haven't seen it happen. Apparently only happens after I go home for the night. So, I opened the diagnostics and ran all the tests and everything seems to be ok. I'm going to talk off the back panel this morning and check all the connections to make sure everything is connected properly. Any idea on what could be causing this? Every time I boot the machine up in the morning, everything seems fine but then starts acting funky around 8-9 at night.

Verify the voltage on board and make sure its between 4.9-5.01v, manual states these values.

That sounds like your power supply is starting to glitch. Maybe the filter caps are going bad. Computers and TTL logic likes nice, stable power.

Do you have an oscilloscope? If you do, look at the AC ripple on your DC power legs. I'll bet it is starting to get out of whack.

Replace or rebuild the power supply would be my suggestion.

Thanks. I'll check the power and go from there. Appreciate the support!

Here is a little more detail.

You can also look at AC ripple with a good volt ohm meter.

Good is a lower scale that will read Millivolts. If your meter has a low scale of 4 volts, it won't be able to read.

Setting on AC, measure voltage on your DC rails.

It won't hurt the meter.

If you see AC voltage, note how much. TTL logic doesn't like above 0.5 vAC. Computers are similar.

High AC "ripple" on DC rails indicate you have failed / worn filter capacitors, or a failing power supply.

I don't have an oscilloscope so I'll be checking the power supply with my multi meter. Thanks for the follow up. It's always awesome to learn from people who know way more than I do!

Power supply was low. Adjusted it up and checked it on the board. So far so good. Thank you for the help. Problem solved!
