So while I wait to get a replacement capacitor for my first PS2 5V project board, I decided to pull out the last of my PS2 boards, a 3V board marked "good" and give it a checkup.
All went pretty smooth, but I had to fabricate a rudimentary 3V battery to provide the power that the 2.4V pack couldn't. It's old, has almost no charge, and I'm not sure I have a way to charge it. So I doubled up some 1.5V alkalines just for the test phase.
Got everything hooked up, but I left the motor, light and smoke terminals unconnected.
Speaker I tried first was an 8 ohm. When I powered up, I could hear the relay click, and I could hear the speaker "ramp up", but it was EVER SO SOFT. If you were more than 6 feet away you wouldn't hear it. I checked that the volume pot was adjusted all the way clockwise, but nothing would raise the volume to a reasonable level. But otherwise it sounded like it was making the right noises.
Also noticed that the bulb connected to the front headlight pins wouldn't light. It would when I applied direct power to the socket, so I know the bulb is good.
But best news, I was getting the variable voltage across the motor pins, so I know it would push my engine (If I ever got an engine for it). So I would generally rate the board as "good, with things to troubleshoot"
I tried a 4 ohm speaker but no difference so I immediately turned off and put the 8 ohm speaker back.
Any thoughts?
- Does the absence of any connectors on the smoke harness, the secondary light harness or the motor harness cause trouble?
- Does my 3V AA battery pack feed it too much voltage? I saw you guys were feeding it 5V through a capacitor when making BCR's so I thought I'd be safe.
- Does it matter that the headlights don't work? Is that a clue to anything?
Thanks a bunch.
