Hello everyone,
I have a U.P. sd70ace 6-84106. This only has maybe 1 to 2 hours of run time. I'm currently having a issues with the sound. Just recently For some reason the engine idle / RPM sounds seem to be lower in volume than the bell and whistle. And after tonight of about 5 minutes of use, now I have no idle sounds / RPM , but I have bell and whistle sounds.
There is only one speaker in the engine itself. The only thing that I could think of would be a issue with the sound card it self. Just wanted to hear your Thoughts,
I'm pretty savvy with opening things up and trying to fix it , but if it's a computer board look out ,back to Lionel it goes.
