Battery dash light glows-barely.

My battery dash light glows all the time while running. It is a faint glow only noticed during after dark driving. Battery holds a good charge even after sitting for several days. I do not drive it every day. Alternator has good readings. Off are 12 and running are about 13.

Your alternator has an internal part that has failed; most likely a diode. Mine did exactly the same thing, had the same indication, and the same system voltage. In my case, a main power diode had failed. Your system voltage should be more like 14 1/4 to 14/1/2 volts and anything less will cause the light to show. The lower the system voltage (below 14 1/4), the brighter the glow. You'll likely see the light get significantly brighter when you run lights and such.

HTH, keep us posted...

Hello dn29626,

Mine is doing the same thing and I guess for the same reason, so I have bout anew one and it travels behind my Seat, Just in case it dies out past the "Black Stump", In which case I will crack a Stubby and change it in the shade while my Wife reads our the Wedding Vows of Forty Years ago, and I read the Menu
of instalation, then crack another Stubby and wash my hands!.
