A relay and a blue thing. I don't know what the blue thing is, but it's wired like this:
I did test it with a 12V battery and my motor. Yup - no spark when I disconnect the green "ignition" wire. But is this device actually doing anything besides transferring the inductive spark from inside the on-off switch to inside of the relay? Who knows. And the way everything is glued together, it's not like I can easily replace the relay if it lays an egg.
What is the blue thing?  |
The "blue thing" appears to be some kind of snubber capacitor designed to absorb surge voltage spikes in a DC bus.
It would be nice to know the actual part number on it, but its most likely on the top that's glued down or the side touching the side of the enclosure.
