Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. Have you verified the current battery is good and passes testing? Not just "has power" but passes a test with test equipment? Have you verified - after a known good battery is present - that the charging system puts out proper amperage and voltage at 2,000 RPM of engine speed? If somehow both of those are "good" - but the battery is low in charge - then the next step would be to test for a parasitic draw to see if something is drawing the battery down. If all is good and you're still having electrical issues - you must have a wiring or cabling issue. My guess, however, is that you'll find a problem with the battery and/or charging system when actually properly testing it.
