Starter problems - electrical malfunctions
My starter sometimes runs while I'm driving. If I'm coming down a hill, or up to a stop, and I'm letting the engine brake me, the starter will begin to run, but the gear won't engage. It just spins non stop for about 10 or 15 seconds - sometimes I have to disconnect the battery or hit it with a hammer or something. It does this once or twice a month. Something is giving it the signal to run, and power to do so, when it shouldn't.
Also, under the same circumstances (engine braking at 2500-3000 RPM), my lights will sometimes flicker and dim very briefly, radio might cut out for a half second, and then it all comes back.
I'm rather stupid electrically, and I'm afraid there's something wrong in the wiring maybe. This all started when I replaced the starter about a year ago. It's installed correctly, and even if it was messed up, would that somehow affect the other systems as well?
