My car won't start have petrol battery's charged

Mercedes Benz 300SE Won Start

Mercedes won start

if it wont turn over 1st check the ground s on the car and the battery 1st. your battery can be fully charged and the car will not start even over night this can happen. then look at the starter. Note: if you have over 109K on the car and the timing belt has never been replaced you will need to have this checked as well.

Hi
Is the car Petrol or Diesel fuel ? If its petrol I would think the petrol has gone off after 3 years ,it turns a dark yellow in colour I had the same problem
Hope this helps Nick

what symtoms and type of car.. need more info..repost..

Sounds like your battery is just too dead, has enough juice to light up the system for a minute but cranking drains it and if it wont charge then deff fried, you could try removing the battery and starting the car with cables to confirm the starter still works. If a bettery is too dead then when you are jumping it, it takes to much of the power just trying to get through the battery.

have you checked the battery connections, or charge-up battery if dead

Sounds like you have a toasted battery or alternator. Have you performed a load test on the battery? Have you tried to charge the battery? First remove the battery and charge it externally from the vehicle. If the battery won't hold a charge, or won't hold a charge of 12 volts, replace it. Once you have the vehicle started, test the operation of the alternator. It should be putting out at least 13 volts back to the battery to keep it charged - if it is putting less than 13 volts or more than 16 volts, replace the alternator.

Hello and welcome to FixYa!

If the battery light is on, I strongly suggest that you have the battery charged. It can be an indication of a weak battery or a faulty alternator. If the battery light still on after charging then the problem will surely be on the alternator itself. If that's the case the alternator should be replaced to resolve the problem.

If the battery won't hold charge even on a new alternator then the problem will be on the battery itself. It surely is in the end of it's service life and replacement will be necessary.

You may try to reset it to by removing the positive battery connector, letting it sit for at least 5mins. then reconnect it again. This will reset the system and can get the battery light off.

Hope this helps and thank you for using FixYa! Have a good one!

This sounds more like a low battery. Try to jump it if possible. If not, try removing the battery and taking it somewhere to have it charged. Once you know you have a good powersource(i.e. battery), then try start. If it does, then have your charging system tested for proper charge.
