I suspect the sequence of events is the following: The bike has developed some non-battery-related fault which prevents it from starting but doesn't prevent the starter motor from running. You tried to start the bike with a good battery for 30 seconds. The current it takes to rotate the starter motor is very high. That current over 30 seconds heats all ...

Your car is equipped with both an immobilizer and a theft deterrent alarm (the beep beep one). Just the theft alarm beeping WILL NOT prevent starting, only the immobilizer does that. (Assuming this is the stock alarm and not aftermarket.) To disable beep beep alarm you must either cycle the key in a door lock or use the keyless entry buttons on a programmed ...

Many years ago I had a similar problem, it turned out to be the boot light was staying on causing a small current drain. A very helpful garage mechanic climbed in the boot to find it.

The battery has been damaged by letting it go too far below 12v for too long. It needs replacing. When you fit, or before you fit the new one, make sure it is fully charged. If the vehicle will only see occasional use, then use a battery tender or charger to keep the battery topped up.

You need to check the other end of the cables for security and tightness. There will also be a bonding strap between engine and chassis / body or gearbox to body - usually across a rubber mount. These can break and cause the symptoms you describe.

The goal is to start the car (specifically spin the starter motor) not charge the "dead" battery. The good battery can be wired to provide power just to the starter motor since the starter motor is grounded to the chassis. If you connect pos-pos and neg-neg, the “dead” battery begins rapidly charging and Hydrogen gas is produced as a surge of ...

You method is sound, first you need to make sure you've found all the fuses. I don't know the Cherokee, but fortunately the internet does and apparently there's a passenger as well as an engine bay fuse box. You'll probably find your drain is a shorted courtesy light or something like that in the end. The alternator is possible source of battery drains, you ...

I would check all the terminals and connections - it is possible you disturbed something when you replaced the battery. The battery terminals need to be clean and tight

The short of this is yes, you MAY have damaged your rear brakes. The only way to tell for sure is to have them inspected by a mechanic (or if you know what you are doing, inspect them yourself) and determine if there has been damage, what is the extent of it, and what (if anything) needs to be fixed. In some cases the damage is just premature wear of the ...

You have it backwards, battery insulators are used to protect batteries from excess engine heat rather than protect them from cold, as extreme heat is worse for batteries than cold. Car batteries have no heat source, so an insulating blanket is only going to slow heat loss, a car battery sitting overnight will still reach ambient air temperature.

Modern fuel injection ,electronic ignition ,should start easily down to about 0 F (outside). So I would not bother with insulation. Insulation will slow cooling but overnight in wind it will cool to about the same temperature ;so, no real difference in battery temperature / voltage. Long ago ,with carburetor and points ignition, I took the battery out and ...

The "classic" warning light was connected between battery positive and the alternator output. This would then exhibit various states of illumination, which with experience, would tell one what was wrong without having to do all the tests stated in the workshop manual. So, if the light was on solid bright then the alternator was not charging and ...

Got a 1998 Toyota Camry that has an empty battery and am wondering what the best course of action is. Why is it empty? Is it empty because the battery is old and dying and won't hold capacity? Or is it empty because you yesterday forgot the lights on? The correct course of action depends on the reason for it being empty. If the battery is good but you just ...

If the battery is completely flat, then it will have been severely degraded in capacity. Lead acid batteries don’t hold their full charge after going completely flat, so it would be best to replace the battery and make sure this doesn’t happen again. However if you want to try to charge it, it will be less stressful for the battery to be slowly charged by a ...

A better solution is to fix these two problems and correct a few other common faults. Use a voltmeter or a test light to confirm if the switch is receiving and outputing 12 volt power. Then go to the bulb and see if it is receiving power. Even with power, the bulb would not work if the ground side is poor, or the bulb is open circuit. Also, look for ...

To charge a battery, you need a battery charger. That's because the charger needs to do multi-stage charging that is correct for the battery type you are charging - lead-acid, lithium-xxxx, etc. so it doesn't hydrolyze all the water out of a lead-acid wet cell destroy a sealed lead-acid by hydrolyzing the electrolyte set a lithium pack spectacularly on ...

No it won't hurt the battery life. A quick fix for this is a penny placed beside each post to gather the corrosion.
