battery/electrcal drain
OK..
I've replaced the battery,alternator, starter motor; all within the past 6 months.
Why?
2 reasons. one, excessive battery drain. two, 128000 mi and
15 years.
As the original owner ,i've always, since day one, felt the drain on the battery
very excessive over the course of ownership. (5 batteries and 3 alternators later)
but it has gotten much much more severe in the past month since
I've started to drive it regularly.
I bought a 1 amp trickle charger and kept it on every night.
But after a full day of being idle, the starter barely cranks.
the voltage is down to 10.5 before I cranked it.
Had the battery load tested, had the alt checked..OK
I disconnected the battery overnight and re-connected in the
morning..started fine.
I took a 12v brake light, disconnected the neg cable,placed the bulb in series with the battery terminal, and it lit at full brightness.
The charging volts reads 13.5-14volts when running.
What is wrong here???
