Car is a 86 firebird with a lsx swap Had a wire burn under my dash from the c100 firewall connector so i replaced it only to now find out i have no power to half of my fuse box. Replace the ignition switch no luck... does anyone know what wire the fuse box gets its switched power from? Examples of fuses i have no power to are the Back up/turns and cluster when i replaced said wire could i have missed a split in it? Here is the wire i suspect may have split off of the one i replaced
Re: No ign power to fuse box but power to coil....
For your 86 , power starts at the Fusible links andfeeds into the cockpit thru C100 ( PIN 'A4"). Then it gets factory spliced to 3-4 other things - one of them is the lead to the ignition switch.
** Both Red wires at the ignition switch should have 12 volts at all times.
When you turn the key the ignition switch will supply power to the heavy gauge PINK wire to the fuse-box and feeds the GAUGES, ECM IGN, and TURN B/U fuses.
** Guessing that either you missed a burnt-out RED wire feeding the ignition switch itself, or the ignition switch - or the wiring to/from it - is the problem.
