I have a 92 Civic and I think the alternator has had it. I had the battery tested and it was fine but needed recharging. The wipers and electric windows barely worked when all this was happening and the car actually stalled while cruising down the highway. Anyone know how to do a quick test to see if the alternator is working (or not) and how does one remove the alternator without paying big bucks to a mechanic? Do you have to go about it from under the car?
