Separate names with a comma.
So our 2007 with around 134K miles is making a sort of roaring noise from the front end which increases in volume with speed, but doesn't change...
Those rows are, top to bottom: ACC, IG-ON, and READY. There is a current draw from the battery in the first two cases (assuming all the doors are...
That behavior is also common with a cracked solder joint. Not to cast aspersions on the soldering skills of the OP, but are we confident that...
I bet thieves bypass the fence in short order. The simplest method would be to bump the car off of the pads with another vehicle. That would...
Carabiner's work well for this too. I put something through the protruding loop so that I don't forget it's there and close the hatch on it. Pick...
Don't forget the eye protection. The light from electrical arcs can easily burn a hole in your retina - those do not heal.
Also there is limited competition for what market there is. That brings in monopoly or duopoly pricing, which drives prices up. With regards to...
Fun project. However, last picture of first post - rubber coated wire going through stiff plastic hole isn't a good idea. If the rubber is...
Isolating the battery from the car while charging and resting avoids the possibility of any intermittent parasitic load changing the "full"...
Nice theory. The problem is that observations don't agree with it. It is a common observation that MPG decreases as the 12V battery declines....
Anybody have a link to a table or plot of I vs. V for a healthy Prius 12V battery at various SOCs? The AGM battery Toyota sells, not a generic...
I wonder if the bit of duct which exits near the battery can get displaced, for instance by being installed incorrectly. That might put some...
So, here's a question: in normal usage, defined next, why is the 12V measurement in ACC mode, or better yet, directly at the battery with the...
There is a black box right next to the battery which has electrical wiring and says something about the brakes. Perhaps when the battery was...
Update on that Harbor Freight tester - some care is needed to make solid electrical connections. We just tried it on my son's truck, which has...
Under normal circumstances the battery would only be putting out (more than) 9A for a fraction of a second when the car turns on. After that it...
This car must have gremlins or evil spirits. With the battery out I measured the resistance from the bolt near the fuse box I was using for a...
Exactly. The only way that much of a voltage drop makes sense with so little current is if there is some sort of junction between dissimilar...
Why are the voltages at the jump post and the battery not the same? On our 2007 there is a roughly 0.2V drop between the voltage measured at the...
No rain this morning so I set out to find the source of the parasitic draw - and it was gone. Without having turned anything on, just opened the...
