I'm going to have several electrical questions. 1st, Is pin #8, on the 14 pin plug at the relay board, the only switched 12v+ source in the engine compartment? TIA, Kent

Spoke, no direct connections between the ECU and relays. Both the relays share the same switched ign source. The starter relay is grounded on a dedicated ss ground stud at the firewall. The neutral switch is grounded at the stock tranny ground stud along with the tranny grd and back up switch grd. I remember hearing that ECU's can suffer from ground problems and thought maybe a stray current to a nearby ground might influence the ECU. I guess not, huh? I freaked as ECU's are Voodoo to me so I wanted to disconnect the relay quickly to see if it would return to normal. It did so I will go back and explore further as Mike suggested.
Mike, your probably onto something re: a wiring fault. I re-used a "4 fuse" block that has spade fittings on the bottom. (IMG:style_emoticons/default/barf.gif) I'm going to 86 it and install a 6 fuse block with the screw terminals on the side. There are 3 circuits on the existing 4 fuse block. Backup lights/bat fused to ECU/switched fused to ECU. Sounds like I'm in the right neighborhood to begin my search. I appreciate all of you guys holding my hand while I tackle this. |
