Need to run our newly built 385 stroker on the engine test stand.
We have a TB IV distributor and V8 (22 degree) module in it.
Ignition Module is the mount on distributor type.
Following the wiring diagram in:
Mercrusier Service Manual 17
Section 4 B
Page 4
1. I see the power wire (purple) going from positiv battery terminal to + terminal of coil (Purple) then on to connector pin 3 (going from left to right, looking down from top)
I did that.
2. From - terminal of coil I ran a wire to the 5th (left to right) terminal of connector.
3. Ran a ground from 1st terminal of connector to negative battery.
I am getting no spark this way, or various permutations of it.
Here are my concerns (have a raging cold so not thinking the straightest):
Merc wiring diagram shows only 5 terminals in connector, but there are 6.
So......which one is unused?
I have tried connecting the white/green (that would go to the shift interruptor) and white/red connectors (that would go to terminal 2)from distributor body and no spark, and disconnected the same results.
What I am asking for:
An explanation of how to hotwire the TBIV to run on the test stand....
Anyone?
