I have a 91 5.0 and I've been having charging problems I can't seem to track the problem down i bought a new battery and a new alternator but its still its still wont charge the alternator is brand new and won't pull a magnetic pull on just like the old one, Any ideas?
Possible relay sticking.may take battery and altonator somewhere and have it checked for your sanity ?.even tho it's new not sure how long it set on shelf before you bought it
Since your car is a 91 the Fuel Pump Relay would be under the drivers seat and not in the engine bay, The 92 and 93 had the Fuel Pump Relay in the engine bay.
Also check to make sure the solenoid is anchored tight to the inner fender.
If the solenoid isn't making good contact since the back of the solenoid is metal and the ground for the solenoid, so you want it screwed tight to the inner fender.
Sorry guys for the late reply my phone broke and took me a while to get another but I still haven't figured out the charging problem it still won't charge and just runs off the bat until it becomes depleted
Yea and baught a brand new one too and then had it tested I read somewhere you have to trickle the alternator when you crank it but I took a test light and its not getting power to the alt
Did you replace the alternator plug. Most new ford alternators for those year models come with one. I definitely would check there, its common for them to melt or breakdown on the foxbodies.
You should be able to check all wires with your test light to find out which are not getting power. Start from battery check each wire one at a time between the different components of the system, until you find where it terminates. If you can hear your solenoid clicking when you switch the key on you are good...if no click, bad...unless it is an intermittent problem. That's why I say start at battery, make sure power is getting through entire system.
Yea tomorrow ill go after it with a test light and try and find we're its losing power and thanks almost stock for the diagram it should help me alot
