rear voilamart 1000w controller connectors?

[m0rg5]

Hey all, long lurkerer, 1st posterer here.

I'm frankensteining together a custom steel bike build (extended frame, reinforced seatpost base to add extra support arms for floating rack off seatpost) with a Voilamart 1000w rear kit, and have not been able to find from web, seller et al any detailed specs, pdf, etc re: the connectors, etc.

I've matched coloured to coloured connectors, have a 10ah 48v battery, and wheel seems to run, yet I've got one Black/Red connector left over from the controller, I sparked it while trying to gauge the volts coming out w' multimeter and now I can't get any voltage out of it at all, yet rear wheel is still spinning.
Was assuming it was a light output - but with such a spark, grey residue left behind, seemed 48v?

Anyone know what it is, have I likely blown a fuse inside controller?

EDIT: here 'tis:

Here you go, from an ebay Voilamart listing,

Thanks @docw009

So, 11. LED as assumed, but why such a spark!? How many amps are they pushing through it? I assume 12v?

Are there fuses inside this controller?

Any other specs anyone?

Most “lighting” circuits on ebike controllers don’t carry enough current to power lights. They can usually only support relays that would control the lights. If the motor still works, then you were lucky enough to only fry the lighting circuit (there typically isn’t a fuse). If you want lights, it’s easiest to keep the ebike parts and lighting separate.

My lighting board inside the controller blew from lights. It put out pack voltage, not 12v. I didn’t know until it was too late. You’ll smell the crispy goodness if you open the controller.
I despise red the board and continued to use the controller. Worked great for a couple more years then I removed that system.
