Hello all. My son owns a 92 nissan sentra. we had to replace the alternater because there was a crack in the radiator at the fill cap. The cap was repaired but now when my son makes a turn the battery light comes on but goes away after the turn.

Sorry, the alternater needed repaired because the radiator was leaking from the fill cap on to the alternater and shorting it out. I’ll check the cables. It could be sliding. Thanks.
