I have a 1975 914. Electrically it’s pretty sorted out. No bad wires, fuses all good, no major add-ons like amps, other items. No parasitic draws. However twice now when I’ve disconnected battery to do electrical work, when I reconnect the negative battery cable I’ve had a dead battery. Both times disconnected for about one week.
When I then put on battery trickle charger for a while it charges up, then runs fine(starts every time, doesn’t go dead). First time I’ve ever had a battery go dead when negative cable is disconnected. Bad battery or ??? Your thoughts appreciated! PDXBob |

I would put it on the charger for a couple days then take it to your FLAPS and have them run a load test.
