HTH can you miswire this? Its pretty simple. Points wiring is even easier, 5 wires!
Boating friend witnessed 3 boxes fail in 2 hours on a big engine powerboat. I guess the guy had some issues, but he was saved on the river when another passing boat guy asked him what was wrong. Told him and the guy pulled HIS spare from under the seat and handed it off to him. plugged it in and away they went. I understand the guy gave it back to him at the boat launch. I wonder what the root cause these failures are, flyback voltage clamping?
