1994 Acura Vigor Repair Question
Dead Electrical system with no cranking
Check the main fuses and the ground connection at the transmission for the battery cables.
You mentioned battery voltage at 100 A main fuse, are you getting battery voltage at both ends of the fuse?
No obvious relay/ fuses for crank/run circuit bad -cable grounds good . The accidental reverse polarity jump start caused the crank and run circuit to go completely dead. Could it have damaged an already worn ignition switch? (burned contacts etc.)
1 question asked
Did you test the 100 A main fuse? You must have battery voltage at both ends. Reversing polarity would normally casue the main 100 A fuse to blow first.
Even if the ignition switch is bad, you would still have the tailligts, are they working?
