This car starts up fine, the battery according to charger has 100% charge.

But on three times in last 2 weeks, it started fine, but acted like a bad battery after turning off (running a short time). A jump would start it. Or just throwing on charger for 20 minutes.

Terminals are grease free and tight and seem grounded-
weird. I would go out and buy a battery but doesn't look to me like a battery issue.

Any thoughts?

See my profile.1st check for clean tight connections on your SOLINOID. Pasting in something I wrote to Ford trk. Having SIMILAR ISSUES. HOPE IT HELPS, UPDATE ME, please

Newer computer stuff boggles my mind, Older Fords(maybe new Fords, too) Like all of my Pap's vehicles, have a VOLTAGE REGULATOR (seperate from ALT)[which you made no mention of] mounted on fender etc. GM builds theirs into ALT. VOLTAGE REG. May be bad OR just not plugged in well. This may account for NO CHARGE or TRK running on BATT only. Local parts store(older/experienced employee) can show you location (IF ONE THERE) maybe test yours or get new one. See my profile
