i'm not usually one to throw in the towel, but i'm getting close - here's the story:
yesterday i had a new exhaust system installed (more on that later) - nothing was done to the wiring anywhere - we never got close to any of them - the battery was not disconnected - everything worked perfectly
well, almost
i was having charging issues - the battery would not take a full charge, nor would it hold one - year and a half old red top optima 3478
after taking some test drives, and feeling pretty good about myself, i shut the car down and went inside to settle up - when i cam back out and turned the key, DEAD! - no lights - no bells - nothing
voltmeter said 12.4, but nothing anywhere but at the battery - ok - test the battery, sure enough, bad battery - ok fine - get new battery and install, right?
wrong!
new battery in - key on - lights and bells - cool -
wrong!
one turn of the key and DEAD! - ok - 3 hours of sorting point to point looking for bad continuity, and i found a bad main ground - cool - fixed that - started right up - great
wrong!
now my danged airbag light is on and i have a faint glow on my turn signal indicator on the dash, and no signals work - not left turn - not right turn - not flasher - if i hit any of them, the glow turns off and the light glows bright green, but no flashing and no bulbs on the corners lighting up
yes, the bulbs all seem ok - yes, i swapped out a relay - yes, all of the fuses are intact
everything else in the car works great
i'm headed to the stealership to reset the airbag light, and pick up a different relay - i'm hoping that takes care of it, but this is really weird
anybody have any thoughts? i think i've been grinding on this too long and am missing something obvious
