Hi All,
The last few days I have had a riddle to solve and haven't. My Son owns a 2011 Kia Soul and had a very nice battery I could use for my Healey. When checking the battery, it red close to 20 volts if the car was running or not. Surprised by this condition, I placed my charger on the battery and for 2 days with the car not running, let it do what ever it could do. It did bring the voltage back to 18+volts but no better.
Changing the alternator with a new Denso unit, I reconnected with the same battery and, after running a bit, found the voltage to still be at 18+ with or without the engine running. Although the replacement Denso Alternator does have a built-in regulator and is brand new (not rebuilt), I was expecting maybe 13.6 or even as high as 15 volts at the battery which would not bring the battery near the 18+ volt readings registering on 2 different separate hand held gauges.
So, what could have caused this battery to go so high and how can it be brought back for use in my Healey (with an alternator).
I appreciate that this is not a direct Healey question and the regulator in the Kia alternator must have failed in some way. However, this is a 1year old battery and would have been a perfect replacement for my 12 year old in place unit.
Thank in advance,
