Idle hunting issue

Durandal · 07-25-2010, 12:43 AM

At long last I traced all my problems to a bad battery. It had never been below 12 vdc when I checked it but after doing some testing, I found that it wouldn't hold a charge much past 12.15 volts. If you charged it up to around 12.7 volts with a charger and hooked a multi meter up to it with nothing else connected you could watch the voltage drop and in about 10 minutes it was at 12.05. It would never drop below 12 volts so I never thought much of it until this test.

Replaced it with a new battery and after a test drive the voltage is reading 12.9 and not dropping. Roughly 1 volt makes all the difference in the world after factoring in the resistance of the wires.
