Jeff,

 

I have the injectors wired the same way as you describe.  When the engine is running below the staging point, if I turn off the power to the primary injectors and then quickly turn on the cold switch, the engine continues to run just fine.  I just have to remember to turn off the cold switch at nearly the same time as turning the primary injector power back on or the engine will get twice the fuel it should.  It’s been awhile since I tested this, but I think things work the same way with switching the secondary injector power.  It also didn’t matter if the engine was above the staging point, that is, it would continue to run just fine.

I assume what Bill and Ed mean here is: If you disable the primary injectors, the secondary injectors (if enabled) will remain operable, even below the staging point – they won’t be automatically turned on. This is not actually mentioned in the manual, though does make sense.   I do not have the DPDT switches but rather have separate PRI and SEC power switches plus the Cold Start switch. To test the above feature (which I have not) I would have to first ensure that the Cold Start switch is ON … right now if I disable the PRI-only below staging point, my engine quits. Jeff
