I helped my dad wire his trike, and he has a key switch on the dash and a run/off switch on the handle bar. I wired them in series so they both have to be on to start the trike.
The thing is, if you turn just the key to "off", the trike keeps running. If you turn just the handle bar switch to "off", it kills it as expected.
If you turn the key to "off", the engine wont start even with the handle bar switch to "run", so why would the engine keep running if you turn the key "off"?
Is the coil back-feeding somehow? It seems like the key being "off" would open the circuit just as well as the handle bar switch would...
Any help is appreciated.
