Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Have you had the battery tested to make sure it is o.k.?If it has a shorted or dead cell in it this may be causing this issue here.

The other issue I have seen is a fault with battery cables or alternator cables being loose or corroded at or leading to the battery needing cleaned and tightened.This causes the battery light to come on as well.If all of these have already been checked and found to be o.k. let me know.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
