Dennis,

 

I discovered today that my sec= ondary injector disable switch was bad.  Flipping the switch gave no c= ontinuity either way.  After flipping it back and forth several times, it began to make a high resistance contact.  I guess the movem= ent caused the contacts to clean off a little.

 

I am using the Carling S700 se= ries switch espoused by Bob Nuckolls and sold by B & C.  This was = a 2-3 switch that is double pole and is on-on.  These switches are pretty inexpensive…$7.50 each.  I was getting ready to  or= der a couple more switches and got to thinking about it.<= /p>

 

The injectors pull pretty high= amps I think pretty close to the switch capacity.  Does anyone know h= ow many amps the injectors pull?

 

Is there a switch with pretty = high capacity that is on-on with push tabs that I could substitute?

 

Bobby suggested some Honeywell= switches but they are not on-on and don’t accept the push tabs.=

What type of switch are you using to disa= ble the primary and secondary injectors?  I was using  "rock= er" switches and I found they failed to make good contact - failed&nbs= p; "open".  This would turn off the one set of injectors but not tell the computer to = double the on time of the other injectors.  I replaced all m= y switches  rocker switches with "snapping" toggle sw= itches.

 

I want to thank Steven Boese, Bobby Hughe= s and Mark Steitle for all their help in diagnosing this problem.

 

I never could make the switch fail during= ground run testing!
