Customer Question
I have an awful...

I have an awful grinding noise when I start the rig , same sound when you try to start an already running vehicle. I replaced the ignition switch and now it seems battery is dead and still make grinding noise??

Mechanic's Assistant: Did you test the battery with a voltmeter? And have you ever changed one before?

It’s brand new and tested good before ignition switch replace unable to test now

Mechanic's Assistant: What is the model/year of your Ford?

2000 expedition 5.4

Mechanic's Assistant: Are you fixing your Expedition yourself? What have you tried so far?

On my 3rd starter 2nd battery 2nd starter relay and a new ignition switch, wires things happen , wipers come on when you turn on key

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just that I think it is an electrical issue and not starter or flywheel

Hello and welcome to Just Answer

this sounds like the starter motor clutch / throw out bearing may be jammed

often they can be given a new lease of life by removing the starter

and using brake cleaner to thoroughly degrease and remove all debris then apply some fresh copper grease to the pinion shaft and try re-fitting it

one other thing to check is if the ring gear isn't damaged and that the mating face for the motor is square and flat

also check that castings aren't cracked or deformed

Also check the resistance of the main positive lead that runs down to the motor as anything more than a few ohms and it should be replaced

A faulty reman starter with incorrect final installed clearance has damaged the flywheel along with the starter bendix, both will have to be replaced and before starting the first time the damaged ignition switch will have to be replaced, unfortunately this will require transmission removal.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
