now I'm really
On the electrical system's ground integrity .... this seems to be an issue for every gen vette. Plastic cars have issues. When I first got mine She was 14 yrs old. Since it was winter in NY I had all winter to take apart every connector and ground I could reach & find easily. I cleaned all the connectors' pins with contact cleaner & pencil erasers and then coated with dielectric grease. I paid special attention to the rubber ribbed gaskets on the connectors. I massaged them with the dielectric grease. Taking care of the grounds is easy...you know that drill, star washers are your best friend. Took me about two months a bit at a time. I guess what I'm saying is that I ( knock on wood ) have not had much of an opportunity to chase electrical issues due to poor or / and oxidized connections. To this day every two yrs I go thru it again just to be sure. It don't take that long as the stuff stays clean mostly and I'm mostly just shooting more dielectric in the connectors & on the rubber gaskets. Oh, and this seems very important or to me it is. The electrical standards for automotive wiring insulation changed with the 92's (?) and the older stuff is crack prone and chafe prone. I found that over at the NetRegistry site in the TSB section I think. So I eyed up all the runs and took action ( mostly using rubber vacuum hose & heater hose & zip ties. Yea it ain't pretty! ) to insure against chafe & vibration. I did the same drill when I got to change my OE injectors...man what a cluster F___ under the plenum! At least it made it easy to get to the back of the block! Watch now I just brought electrical nightmares down on me by saying this!!!
I guess what I'm trying to say is that I know I stink at electrical diagnostics so this seemed prudent for me to do. Also, by extension....I'm fairly ignorant and proly should keep my trap shut as I'm not much help in the electrical department...just ask my Z-Brother Lou from Norwalk!!!
