Well, ok, It's only my car that I hate right now.
Stuck the key in the ignition and turned it. Nada. No dash lights, no beeps, no click, no radio. Nothing. The headlights were not left on. Good thing I have a booster pack. Hooked that up, still nothing. Nada. The booster pack measures 75% charged and doesn't go down when connected to the battery in the car. BLARG.
Call work, I'll be late, blah blah. Tried to call coworker but he was already almost here.
Try starting a couple more times. Nada. Check fuses: all fine (including 100A main fuse). No smells of electrical burnination. Just nothing.
Fortunately my other coworker hadn't gone to bed yet and was kind enough to give me a ride in.
Of note: This is a 1991 Ford Escort Pony with a 1.9l HO I4, a 5 speed manual, no AC, power steering, or much of anything else. Bone stock, only aftermarket mod is the addition of a tape deck (about 14 years ago; no radio included in the car, it's that bare bones).
I did hear an odd sound when I first opened the hood that could have been a solenoid or relay ticking but it went away. The battery cables are tight on the terminals, and nothing changed when I tried the (-) of the booster on ground instead of the (-) on the battery. There's nothing I can think of otherwise wrong with the electrical system on this car. It behaved perfectly normally when I drove it home from work Friday morning. (I carpooled Sunday night).
I'd hoped to use this as a trade-in if/when I buy a new car in a couple months, now I'm thinking the new car may not be an 'if' and 'when' may be as soon as the IRS direct deposits my refund. Blarglefargle.
