Car Batteries

What would cause the battery light to flash with a new battery and alternator that checks good on a 98 SL2?

Check your owners manual first for info. If the battery and what looks like a thermometer flash together there are 2 possible reasons. The first is that your coolant is low. The second is that the PCM has found a discrepency between two temperature sensors. The IAT (intake air temperature) and the ECTS (coolant temperature sensor).

      • Check your belt tensioner, I've heard that it is common that they go out in will affect both your alternator and your water pump (the reason for your dummy lights going on) same thing happened to me...the part is around $100, but needs to be put in by a mechanic most likely.
      • Something I once found was that there was a short in the trunk lighting, so it wouldn't shut off, and drained the battery.

Your battery light does not flash It is your low coolant light Fill up coolant and you will be fine

actually the belt tensioner went on my car and i replaced it myself in an hr or so. i just had to take off the pass tire to get at it.

The flashing warning light may be an indication that the air conditioning system is drawing too much power from the battery. A weak battery or alternator can be the cause of this problem.

on my old 1.2 clio the battery light came on as there was fault with the alternator and it needed replacing. As far as i know the battery light comes on when the battery is not charging or there is a fault with the battery.
