Sorry I have no information and am only answering so the site will let me opt out! Is the alternator wired into oil pressure switch? If so, it may be slow to close, keeping alternator from getting the field voltage to start the charge cycle. Good luck with it.

Hi my name is***** will be glad to try to help. Are you having any other symptoms such as hard starting, etc? Test the battery with a digital tester for possible bad cells and clean tighten and inspect the battery to starter connections including all grounds. Verify the Alternator is charging 1-2 volts above battery voltage with the engine running. Check the throttle sensor and harness for problems and test the sensor with an OHM meter for opens. Let me know if we need to dig deeper into this.
