I have one from the 1st kit I ever bought. The leads may need cleaned up and Id test it before sending on , but id be happy to send it to you for shipping cost.
Once I found e-s and realized 36 volts would not do it I removed it and used a 12 fet so other then sitting in my garage in a tub for some years it should be fine.
Oh I should add Ill have to find it tho I think I know where it is heh.
Found it. Just needs 5 anderson housings.
