So I’ ve noticed for past few months if I manually turn on the fog lights dips a little then comes back up to original position. What’s strange is if I put on high beams no dip. AC same thing. I only notice it when turning on fog lights. Weak alternator? Maybe electrical issue with fog lights? Fog lights work and original bulbs. I can check RPM next time but it feels like a serious draw.
No worries or need to check it out?
