95 Ford e350 good alternator and battery but won't charge

Check your wiring such as the fusible links in the wiring and do an ohm test if in doubt. Also the wiring in the plug connector for alternator may have backed out or is corroded. Get some electrical contact cleaner and use it where needed. Make sure all your grounds are clean and tight. Good Luck!

That's the problem. I'm having. I checked. The wire harness in an alternator. Actually, I changed it. New battery new alternator the fusible link that's on the firewall next to the battery is good. But it's still not holding no charge. I am getting nothing coming from the alternator. So my question is is there another fusible link that I'll miss it?

Did you check out the battery isolator under the battery pan. It might be bad.

the alternator needs an ignition signal to turn it on. also some alternators have a separate external voltage regulator
