Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
A typical current drain with everything off and un-alarmed should be around 0.05Amp and if its higher than this can you tell me if any of the fuses pulled effected this reading?
Also check that the alternator is actually charging the battery in the car by taking a battery voltage reading with the engine off then another with the engine running. The 2nd reading should be higher than the 1st and climbing steadily. And also check that the alternator is secure to the engine as this provides the ground for the charging circuit and make sure that the engine / gearbox earth strap is secure and the contacts are clean and bright.
if the alternator appears not to be working - take it to a electrical specialist and ask them to test it as sometimes you can replace just the diode pack and this will repair the alternator without requiring replacement
fair comment about the alternator
however have you tried the current drain measurement?
if so what have you found?
do you still need help?
