Subject: Started the vette (89) today and have low voltage, any help? by damien89 on 2014/5/31 18:59:47 Hi everyone, its been a while since iv'e posted here. Today i went to start my dad's 89 vette. When it cranked it cranked a bit slow but its because it had been sitting for a month. After it started i noticed a humming noise coming from the engine but it was really low this noise that i didn't take notice of it as i thought it was my ears playing tricks on me. So i left it idling and went to do something in the other garage, after 5 minutes i go back and again there was a faint humming noise, i looked at the engine bay but i couldn't find were it was coming from. Then i went to turn it off and saw that the dash was really dim, so i checked the voltage and found it was 9.6v! So i turned the engine off. Then tried to restart it and the starter just clicked without turning. I hooked up the battery charger and left it for an hour. After that i started the engine but the voltage was 11.1v and it was getting low 10.7, 10.5 etc after 2-5mins. I checked the battery voltage with a multimeter and it was almost the same as the gauge on the dash. How can i check the alternator without removing it from the car to see if its charging or not? Could the humming be related? Maybe something in the alternator broke? |
