My 12v battery very rapidly declined the last few days. On Monday it started the car fine. Yesterday the engine cranked once and then nothing. My temporary solution was to grab a pair of discarded 7Ah alarm panel batteries from work and wire them in parallel. Car started up fine this morning and this evening, cranked faster than it has in a while.
Caps were at my door when I got home. Funny thing, I couldn't tell which box had the capacitors and which one had the resistor and LEDs in it; they weigh practically nothing!
redpoint5, what did you use to hold your caps?
