Hey guys I have not posted in awhile but car running great except the speedometer needs jumps... sometimes does not work.

I know that I may need to replace speed sensor on diff.

But I have a twist to it if speedometer is not working and I am driving and have radio on I can hear an increase in volume (power) if speedometer starts to work.

Make me think it may capacitor issue but why radio goes louder (fusible link) ?

Anyone has ideas...

Thank you
