Re: Omc Ignition Troubleshooting Help
You swapped the distributor, did you turn the engine #1 piston @ tdc before installing the distributor so knowing what plug cable #1 is.
If not, remove the sparkplug #1, place your finger on the plug hole, rotate the engine by hand until air blows out under your finger knowing that the piston is at its compression stroke, eyeball the timing marks and gently turn on until the timing mark on the ballaner pulley alligns at 0.
The plug cable that correspondents (or correspondents after slightly turning the distributor) with the rotor is #1, the next clockwise terminal is plug cable #3, next #4 and last #2.
The points are set by turning the engine over by hand until one notch from the distributor shaft opens the points at its highest, now adjust the points gap at 0.016. for the 3.0L
Dwell is set with a dwell meter after at 40-45 deg.
To by pass the wiring, mark the wires on wich terminal on the coil they are. Remove them and put battery 12+ on the + terminal on the coil, replace the black wire from the distributor( points) on the - neg terminal of the coil. start the engine and it should spark.
Set the ignition with a timing light @ 8deg. before tdc.
