OMC Cobra 4.3 wiring diagram
 
I have a 1994 Sunbird Cuddy 200 Corsair with an OMC Cobra 4.3 v6 and i need the wiring diagarm for this setup. Does anyone know where i could get this? Does anyone have an image / pdf of this? I just replaced a 7 y/o battery and the original alternator (16 y/o). Everything ran great for about a month, and now I'm back to the same problems. The new alternator wiring is slightly different than the original alt. and I may have it wired incorrectly. Any help would be great.

The Original Was A Prestolite 6 Wire And The New One Is A Mando 6 Wire. I Was Looking For A Direct Replacement And Thought The Wiring Would Be The Same But There Is A Slight Difference...the Ground & L2 Are In Opposite Locations. I Figured That Out Last Night. Also, I Think I May Have The "exc" & "s" Terminals Reversed. Original Set Up Had A Purple And Red/wht To The "s" And The Red/wht Was Like A Jumper To The "exc".... I Found A Photo Online Showing The Exact Opposite. Should It Matter Since They Are Jumpered?

Thanks
James
