No pack power after discharge attempt
I have a HCH1 that I put a 40w bulb on. I didn't see the bulb light up.
Now, the pack shows zero power. I pulled the back seat and measured right at the pack (with pack main switch on) and zero volts. Has someone encountered this before? I wonder if I popped the pack's 100A fuse, but sounds unlikely with a 40w bulb.

Re: No pack power after discharge attempt
Normal. You will only get voltage at the main terminals when the car is on. There is a relay that isolates the pack from the car when it's off.
When you attached the 40W bulb, there was no voltage, so there was no current flow through the bulb.
Discharging without charging first is generally a bad idea.

Right you are. As you mentioned, the main pack terminals are not energized unless the car is running, so 0 volts expected there.
I'm back on track now, finished one cycle down to 90V. Onto the next cycle to maybe 75V. Thanks for the advice.
