Bob and others...

I am trying to use this diode to connect my endurance buss as well as 

follow the Z-19 drawing for the fuel pump and ECU circuits.  The 

schematic I have seen for this device does not seem to correlate to the 

orientation of the connection tabs for the device.  I am stumped as to 

which tab should be used in these various connections.  Can someone 

please help me?  Please assume that you are talking to a 2 year old 

electrical engineer...that is roughly my level of expertise!

Thanks,

Bill B

Note that the (+) terminal ties to the e-bus and is easily identified

by it's orientation (90-degree twist with respect to other three terminals).

Thanks, Bob...That answers my confusion about the E-buss, but I am still 

  stuck on the Z-19 diodes that bring both batteries power into the fuel 

pump and ECU...There are two ins and one out and I don't understand how 

to tell which is which....??



Thanks,

Bill B

  Okay. The gozintas for the diode pairs in Z-19 are the two AC

  terminals adjacent to the (+) gozouta terminal. This means

  you use the 90-degree twisted terminal for out. Ignore the (-)

  terminal opposite the (+) terminal and use the adjacent

  AC terminals for interchangeable inputs.
