Re: battery losing charge when off
I have been fighting an electrical gremlin like this myself.
I replaced the battery with a new 800 cold cranking amp NAPA battery last month. I replaced the relay behind the gauge panel last summer, which helped a great deal, since then, as well.
The car has been starting much better with the new battery, but slowly the dead-battery syndrome has been returning.
It has been below 30 degrees for a couple weeks straight, and sometimes much colder, so that could be something.
The car sometimes takes 1-3 seconds to engage the starter when the key is turned to start. Other times it fires right up. Only a couple of occaisions with the new battery have not started at all, and the battery charger has shown a low battery charge condition.
I am beginning to really suspect the alternator, and the baked, undersized wires to the alternator.
I want to do svxcess's alternator wiring mod, and if the alternator does test as bad, I'd like to get the upgraded alternator, as well...
I have not done a lot of soldering or wiring in a car other than maybe some speaker wires... I kind of wish there were an assembled install kit for svxcess's upgrade.
But if all else fails, perhaps I will just have to bite the bullet and track down all the pieces and put them together. I kind of need the car to get to work, as my wife is driving the Legacy this winter, but work is also the reason I don't have a lot of free time to chase little parts to assemble that wiring modification.
I think first step is going to be testing the alternator output to see what the story is there, first...
but I would appreciate feedback from experience if there is anything I am overlooking on this, or what to expect.
Speaking of which, it is time to go disconnect the battery charger again...
