Z32 cockpit fusebox

[biggles]

greetings all. am a newbie to the site. 1990 z32 non turbo. i have lost all electrical output from circuits running through the cockpit fuse box. can anyone tell me the color code of the main power feed wires supplying the box? are they the 2 large gauge blue connections at the bottom of the fuse panel? where do they pick up their initial feed? this car is not garaged unfortunately and has gotten quite damp. last year i lost the power to the heater fan control at the fuse. jumpered the circuit to solve the problem. i remember being under the hood of a 260Z many years ago on a very humid, summer
indiana night while the car was running. it looked like a swarm of tiny fairies dancing all over the damp engine compartment. thanks so very much. nice to have a place to ask questions. biggles

Welcome!
The OSM mentioned above is probably your best source for tests and checks of the various systems you mention, as you mentioned the Z32 has some electrical connector issues that your dampness situation will make far worse. Most likely you have a pervasive corrosion issue throughout the engine electrical systems and will need to do a lot of testing and cleaning to get to a base you can work from.
Good Luck!
