engine chugs hard when using accessories (Page 1/1)

any time i use any system in my fiero (lights, blinkers, coolant fan, windows), the engine chugs real hard and the radio loses reception and freaks out basically. would this be a short? or a bad alternator or something? any help would be appreciated.

that sounds very much like an alternator issue. It may or may not be the alternator, itself. A quick, FREE test would be to check your belt tension. Your car may run "okay" until you put it under load.

if the tension is okay, check the alternator output.

Seems like an electrical issue. It could be the alternator. Could also be a bad ground connection. Here's some more reading on engine / chassis grounds: https://www.fiero.nl/forum/Forum2/HTML/043240.html
