hey all, man I searched extensively, but didn't come up with anything related. Maybe I'm using the wrong terms.
electrical deets
2003 3.7L 4x4 sport
aftermarket H/U - all connections soldered, shrinkwrapped and double checked against wiring diagram (used successfully in 2 other vehicles)
new front component speakers - all connections soldered, shrinkwrapped and double checked for polarity (I did not use the new passive crossover however...just wired in new ones in place of old...problem?)
everything else is stock electrically
700CCA older Cdn Tire battery, no significant corrosion on the terminals, recently cleaned and lubed with dielectric - very small amount of the powder under (not between clamp and pole) the negative clamp, nothing between or on the clamp.
Battery cables in good condition, newish clamps, double checked that they were tight on the terminals
I have had zero electrical problems until one day a couple weeks ago. It started normally after work, ran smoothly, drove about 5 blocks, parked it, windows up, doors locked as usual while I stopped for 3 minutes to pick something up.
Come back, fob doesn't work. Unlock the door with the key, go to start it - NOTHING on. Not even the mileage would show up. Only one faint click after turning the key, but windows wouldn't even work, power locks nope. No tools either. At least I had cables.
Asked for a boost from a lady with a focus - didn't work. Only a couple very very weak turns, then one slightly louder click. I even tried different grounding locations. So I headed to Costco, bought the biggest battery I could fit (780 iirc) and boosted it a few times then shoved the new battery in the back seat of the jeep (not hooked up). I couldn't keep it running at idle unless I had the gas pedal slightly depressed. It would rev normally, but then the rpm would just fall and then it would die. I eventually was able to boost it and keep it running, but the whole way home (8-10 mins) it needed gas at idle and the dash lights were on off on off, gas gauge needle up and down, chimes going off every 10-12 seconds....CHAOS.
Got home, turned it off and tried to restart - DEAD. Swapped out the alternator with a new one (old batt still in at this point), fair bit better, dash lights were not flashing as quickly, but headlights would go bright/very dim/flickery with the rpm. So, swapped in the new battery and tadaaaaaa purrs like a kitten.
What's going on??? I haven't re-swapped back to the old stuff to troubleshoot yet - anyone else had a similar experience?
Cheers?
