i recently bought a used 21 prime Le, got a charge cord off amazon but it wont charge, chargers light stays solid green meaning "charge complete" car registers i plugged in a cable, i hear clicks from under seat (softer, not like the main contactor at startup) but no charge, ive tried a public charger and it did same thing, and said it was waiting for car to start so it seems it may be either the 12v is not strong enough (I put a jump pack and tried, still nothing changed) or the onboard charger is dead, any way to test that thing besides swapping? I have ordered a second higher-end cable in case that's the issue at home. and ill try a second local charger to see whats issue, but any ideas?
