The battery was as 12.3 volts today and I checked the voltage running with all the lights on.
I saw 13.8 volts at the battery.
This is odd but somehow it seems the 2 month old Interstate battery is bad ? or being drained somehow.
Is there a way to attach a video on this page ?
A reading of 12.3 is a bit on the low side - 13.8 WITH THE lights on is a good sign - I would imagine that once the lights are off - the reading climbs to 14 + volts?
Do you know how to use the meter when measuring milliamps?
Typically you must move the red lead to the other side - and rotate dial to AMPS....
unhook the neg side of the battery - and place one lead on the UNHOOKED side of the battery and the other lead on the lead you took off the battery. LEAVE key alone and see if there is any reading on the dial, should be zero or a very small amount, but damn close to zero.
If you have a reading - pull a fuse and recheck, do this and you will find the "gremlin" in the electrical works.
A battery that is under constant discharge will never catch up!
