I connected the green wire from the delta q to negative side of system, got a big spark, and charger only blinks red 6 times, is this charger repairable? ---

Possibly. An internal fuse is blown. ---

Can this fuse be replaced, or is the charger garbage bound? ---

Yes, if you are comfortable soldering in a tight spot. Take the side cover off where the wires exit. There is a pigtail fuse from the red to the green wire. ---

I replaced mine a few months ago, it takes a ceramic fuse, 6x30mm, Fast Blow axial (pig tails) I ordered mine from Wiltonics, free shipping, came in a pkg of 5. Very cheap and shipped fast from USA ---

I looked in 3 - 72v chargers, 15a 20a 30a Take your pick. It seems 15 is on the small side for 12a charge rate. Some have a separate fuse for the green interlock. Might have been for that as I didn’t research further. A larger fuse will have less voltage drop. Better for sensing voltage. ---

They were 30A 250V I never removed the bad one just piggy back the new on top and soldered the pig tails on. Working great ---

Pretty tight place and didn’t want to disturb any other parts. Hope this helps. Don
