I hope I'm posting this in the right place. I have an 03 ZX3. I have replaced the battery, the thermostat (no heat), the alternator, and the wheel on the tensioner pulley. I thought I was set after the alternator but half way home the battery died AGAIN. The belt seems VERY loose and I am getting a slight burning smell from the heater vents. Would a loose belt or bad tensioner cause the battery to die? After putting in the alternator I went to autozone to have it tested and it started at 11.7 but then went up to 14.8 output and the guy said it should eb fine. Could a belt slipping cause that much of a difference? If anyone can hel it would be AWESOME!!! Thanks in advance!
