Hello, Hopeful for a little help. Have lot of ignition noise on AM frequency, FM works fine. Have checked connections of Antenna at both ends. Have even replaced Radio with after market uniti. Same problem. Could this be a Grounding or Alternator problem. Any help will be appreciated. Thanks !

What your experiencing is just normal AM reception. The stronger the signal, the less interference you'll have. If you have a particular component, like an alternator causing a problem, you can go to Radio Shack and get a filter to install on it but don't be surprised if something else just takes it's place.
