check your coolant level

pm36m,

good first shot. Thank you Mack.

i ll check tomorrow morning,Thanks for the reminder

I would check the alternator alot of times bad batteries will be a result of a bad alternator and vice versa I have many times changed one or the other and a few days or weeks later have to change the other, if you changed batteries I would check all my connections and grounds then start looking at my alternator.The coolant level should only make your electric malfunction light come on and if it runs hot go into shutdown mode not you lose electrical all together.

A little bit low on antifreeze will make the buzzer go off on my '99 telebelt.

The buzzer yeah but do you lose electrical ?

I put about two qt of coolant and everything went alright.i think that my alternator may be at end of his life.

Thank you everyone really appreciated your support.
