So, how’s this for weird…

After talkng with Grizzly tech support earlier today and trying to use a voltmeter to test the start cap, they determined it was faulty and are sending me me a new one. Since it won’t be here for a couple of days and with everything sprawled out right now, I needed the space in my shop so I can get to turning this weekend so I put everything back together and was going to just wheel it over to a corner until I thought to myself it’s not gonna hurt to try one last time.

1st time – breaker on the panel trips. 2nd time – maybe 10th time? Starts up like it’s supposed to, sounds good and runs fine. Switch it over to the other 20 amp circuit I’ve got in the area. Starts up fine. Do this another 10 times or so. Works fine.

I leave it sitting for about 10 minutes and try it agian. Trips the breaker the first time, but times 2..n work just fine again. Repeated that twice more (waiting 10 minutes) and again, same results. 1st time trips, later times don’t.

Perhaps there was a loose connection to the capacitor that was causing my breaker to trip constantly, but given the fact that if I wait the 10 minutes and it causes the breaker to trip, I’m really thinking there’s a faulty capacitor in there that, when fully discharged, isn’t working right and causing some sort of hugh spike in amp draw on first startup. That’s my uneducated guess at least – we’ll see if it makes any difference when I get the new start cap.
