Guys,
I'm trying to finish up wiring of the backup SD-8amp alternator. In Z-10/8 the S704-1 relay shows a jumper wire from COM to the + relay coil. The CROWBAR OVM is then wired also across the coil (+) & (-) tabs.

B&C has a drawing that shows the S704-1 relay being wired with a Diode across the coil.

Reference: http://www.bandc.biz/pdfs/S704-1_Installation.pdf

Am I correct in leaving the Diode OUT? The reason being that I'm using the OVM-14 across the coil and adding the Diode would defeat the OVM's function.

Thanks for your guidance.

Howard
