Hi there, I have a 2008 Dodge Caravan, yesterday while we are camping, we accidentally left the lights ON inside the van and that drained the battery, well enough not able to start the van, I tried a couple more times but theres just not enough power to start it, checked the horn and nothing sounded. I called the park guards to boost it and luckily they have this portable booster, and it did started my Van. But from then on the Mulfunction Idicator Light keep On even while driving, I wonder what is the possible cause for this warning light to be On all the time? Thanks
