Default HELP 86 corrvette fan and wiring problem

My fan caught on fire, I believe because someone wired it to always be on and they didnt put a fuse in the wiring, Now the wiring fried all the way to the two relays behind the battery. All of the fuses are fine and the fusiblee links behind the battery are fine. My concern is my car wont even crank and the dash doesnt work. The radio and lights work and the security light. What should I do next

Here is a fallback plan.

Ability to reset to any one of 3 preset temperature ranges when using a FAN-PWM-TS (temperature sensor)
Intellifan Diagnostics detects stalled or over current fans to prevent module damage
New 16 bit MCU for increased resolution on temperature sensor input
Primary fan low power starts to reduce the current spike on electrical system
Onboard status LED and short circuit protected status output for in-cockpit status light
Includes Quality Deutsch IPD connectors and new silicone rubber button membrane and seals
Improved A/C input timing to minimize fan-run during defrost cycles
Single unit capable of operating on both 12VDC and 24VDC systems
Features:
Reduces fan noise
Keeps air moving in hot engine bay
Water resistant construction
Can be mounted in interior or engine bay
Easy to program
Can be set to any temperature
Works with 12V and 24V fans with up to 30A current draw
LED status indicators

Is there 12 V on both sides of the fusible link "A" ? You say they are good, but was that a visual test or one done with a meter ?
