Vacuum pump wired up – only temporary wiring will clean up and do it nicely.

Found major air leak from hose connected to the servo, replaced and now it sucks correctly and stops very well!

Disaster! – While tightening the nuts on the Main Contactor the stud twisted off, M8 is big, but copper is soft… and I guess I’m stronger than I think!

Good news – I designed my system with a certain degree of redundancy in this regard, I added the second contactor for protection and so in an emergency I could bypass or swap the defective contactor and still drive it. So thats what I did. Bypassed it.

First major outing, took StealthBus from Cumming, GA to Lawrenceville, GA – 26 miles in total.

Starting pack voltage 154v, finish 143v (pretty close to 80% DOD).

Plugged in for full charge, 5hrs at 13A from wall plug the pack back up to 160v – cutoff set at 172.8v (per specs).

Need to hook up a 30A 220V circuit to the garage, so I can charge faster, but 115A/15A ok for now.
