thanks. appreciate the referral. I need to do one last check to see if my M3 board is having the problem sending out the signal for the Rear Left Channel. Once I confirm this, I'll know if the amp is bad or not.

Thanks, I'll give this a go. I finally got Audio to work in my Daytona (had a bad amp) and am unfamiliar with the music it's suppsoed to play with the original DSB board. When I boot up the machine it plays the "Battle on the Edge" song, but no other music throughout the game, nor during...

Yes. I just tested the speakers by plugging them into my Yamaha receiver and all 3 (RR RL SUB) are working. As a test I swapped CN5 with CN6 on the Sega amp. When I do this, the sounds swap from front to rear, rear to front. So doing this the sounds come through both rear speakers, but the...

Found a new amp and I now have sound! Wow. Original amp was bad. Purchased replacement amp from "flightseat" on eBay who claimed it worked, but offered no returns. Well, I got burnt on that one as it was bad. So I bought ANOTHER amp from YATON, and this one was the winner. It works! (LED on the...

I'm trying to update the unit. I removed the Arduino and am applying 20240104.hex since I have a Daytona2. It says "Uploading Failed". Any other way to upload it?

ok. I cleaned up the amp and now am getting some popping sounds in the front left channel (engine left) if I wiggle the lines going from CN6... these three lines lead to the front POT. Swapping CN5 and CN4 and I hear (seat left) popping. So the amp is doing something. lol. Maybe I should try and...

I made a speaker wire to go out of the M3 board to an external amp to see if FX were playing. sure enough, they are. So M3 board is ok. So I made a cable like above and tried to play my iPhone through the amp out the speakers, but nothing. Absolutely dead. Now I'm not hearing any static...

thanks I'm gonna give this a shot

The rear speakers I can slightly hear, and I mean slightly. adjusting volume doesn't increase hum. I changed the pot on the main speakers as well. so would I wire the 3.5mm jack and plug in some speakers? Not sure I follow.

Well, finally found some time and made an audio cable and plugged it from the the AMP to CN7 and CN8 on the model 3 board and got no sound. :(

so I tested the front POT. Checks out at 4.9k ohm. The rear pot is all over the place. 99, 200... this needs to be replaced. Also, I do hear hum in rear speakers. Would the one rear bad pot be killing all the sound? Have not tried connecting directly from amp to AM3 board, this is what you...

Well I didn't have it on VAC. Got 2 readings. On wire is 28.5 and the other is 18.5. Everything else on the D2 works.

just tested the cable to the transformer and it is reading 0.0 What can I do now?

Here's my AMP 838-13475. I tested the power on the CN1 cable which leads back to the transformer. With leads inserted I get 0.0. :( I don't see any fuses in between. So I think my original AMP is probably fine... it's just never had any power.

So I found replacement Amp for my D2 cab, but still no sound. I don't think the unit is even getting power. I see that it gets its power from the sub module. Anybody got some tips on how to troubleshoot this. It's the last remaining item on my D2. Works, but no sound :(
