this arvo i whipped up a jaycar digitial tacho kit for the corona. the thing sounds like a tractor regardless of how much gas you give it so hence putting the tacho in it.
ive got it all together it powers up no problem.
when i hook it to the car it is giving the correct voltages to the PIC +5V on 4&14. nothing smokes. nothing gets hot.
when i hook the signal wire to the negative side of the coil the car refuses to start.
i disconncted it starts ok, touched the signal wire to the coil.. instantly stalls.
any thoughts... ?
oh and its a 1X engine in an XT130 corona/.
