I have not cleaned any of the copper or black stuff or anything like that, I couldn't get continuity from any spot on the board. I checked for about 2 hours testing small sections (about a cm at a time) at different resistances (ohms) and with audible continuity with a multi-meter. While testing I slowly and gently rolled the probe along the copper stuff as well as poking into some of the copper type stuff on the outside of the spot where the lights make contact, but where I could tell the tabs on the bulbs don't touch.
In the sections with the black stuff I would get continuity but it seemed that the black stuff was what was conductive, (I tested a piece of just the black stuff that had fallen off and was resting on my steering column and it was conductive but only on the underside).
All the white spots are just that, not glare, It would appear that when the black stuff started to de-laminate it may have taken some of the copper with it?
The spots where you can see some copper coloring mixed in with the white almost all reads open line or 0 even with the probes being just mm apart on the small patches of copper, The best I got was a short beep in audible continuity on some of the copper where one of the lights makes contact, but only on a very small section, but that spot is just a small blob of copper on the white spots I can't get anything (some kind of glue maybe)?
It does appear that the P.O. did some weird stuff back here trying to get it working (like the screw for the ground on the fuel gauge). he may have tried to clean or remove the copper in some way (you know how them tweekers can be with wiring) lol
so far hard wiring it all seems to me to be the cheapest/best alternative for what I am trying to achieve but I am very open to options seeing as I haven't quite started yet due to lack of money.
