They wear out over time, there could be a parasitic drain on the electrical system, something might have been left on.
No, you have a parasitic drain somewhere in your electrical system. The grounding strap isn't the cause of it.
Bad battery or a parasitic drain
It has a parasitic electrical draw. Usually on the older cars it ends up being the Stereo or an aftermarket alarm. But it could be anything electrical. You have to diagnose it one fuse at a time.
Yes. More so if it is connected. Most vehicles today put a parasitic draw on the battery that will drain it down over time. Parasitic draw should be under .050 mA.
If the defect is causing a parasitic drain, yes.
A battery drain in a Mazda 929 can be caused by several factors, including faulty wiring, malfunctioning electrical components, or parasitic draws from accessories left on. It’s important to check for any lights or devices that may not be turning off properly, as well as inspecting the battery and alternator for issues. A multimeter can be used to diagnose parasitic drain by measuring current draw when the vehicle is off. If the problem persists, consulting a professional mechanic may be necessary for a thorough inspection.
An axiom for virtually all electrical problems, found to be especially true for those of this type: It's a bad ground connection.
could be a short or a parasitic drain in the electrical system... to little info to tell what it is. could be bad earth from battery
Bad battery, Parasitic drain.
There's a parasitic drain somewhere.
