I Am a Mechanic

Ahh, the joys of thinking you fixed something under the hood, spent 770 dollars just for it to do the same crap again! It's not gonna be any warmer than 33 degrees today, but my wife has to get to work tonight and back in the morning safely. Tachometer and lights malfunctioned, power going down to eventual die. Batter-brand new. Alternator-fully functioning. Battery negative cable, able to move it with hand (may be the issue).....battery cable positive, spliced and remounted, tight. Replaced plugs, wires, coil, fuel pump, wipers and headlights, battery, ignition control module. Next to do when warmer, timing belt and tensioner replacement, remark, water pump replacement, battery cables replacement, starter replacement, ECM replacement (was 334 dollars for a new one), fuel filter replacement, alternator replacement. There are 5 things in many vehicles that can leave you dead on the road and stranded. Those are- bad fuel pump, broken timing belt, bad coil, bad starter and bad ecm. Everything else will still allow the vehicle to run, even though it might be crappy, but it will run. All drive belts are good, oil clean and good level, plenty of antifreeze, standard transmission great shape, yessir this is indeed an electrical issue/charging. New relays, narrowed down to poor connection or ballast resistor. Gonna be cold today. I hate working on cars in the cold, but I love my wife lol. So when it warms up just a little more maybe 10 degrees then it's time to kick ass and chew bubble gum.
