Pulley Failure - ZR-1 Net Registry Forums

Locobob · 05-25-2019

One of the symptoms I had was periodic low voltage at idle. Sometimes I'd be sitting at a red light and the voltage would drop down to like 8-9 and the stereo would shut down. It was an intermittent issue and my thought was this was due to belt slippage, possibly from my leaky A/C system. I had my alternator rebuilt a while back and that made no difference so I eliminated that as the possible source. Now I'm thinking maybe it was the pulley occasionally seizing up and dragging down the belt speed at idle. Guess we'll see once I get that replaced.
