This is the worst "right way" video I've ever seen. To crimp a ring terminal, you absolutely need a special crimping tool. Other methods do not provide a secure and permanent connection. With a properly crimped connection, soldering is no longer necessary. In fact, soldering itself can become a risk if the cables get hot: Solder drips and the connection deteriorates rapidly. This can cause a fire because the resistance increases rapidly.

It's usually one or more of the FETs (transistors that bolt to the heatsinks). Take an ohm meter and check for zero resistance across the gate and drain/source pins. If all three leads of the FET read near zero ohms it's bad. Replace with similar/same spec'd part. Fixed. It's obviously not that simple but that's the general idea. Probably 50% of these can be fixed that way without any specific additional knowledge. This one did not work out that way unfortunately. These are very good inverters in my opinion.

What happens if I leave a good deep cycle gel battery on a 15v desulfation cycle for an extended period of time? Thank you in advance.
@knurlgnar24 7 күн бұрын
Gel batteries are very sensitive to outgassing so I'd guess the battery would be ruined if kept at 15V for an extended period of time. So long as the maximum charge specs for the battery are followed to avoid permanent gas pockets in the gelled electrolyte you'd be OK and the process should work - it would just take a long time since you're limited in how much current you can force through a gelled battery.

Can you test without load resister or something else that has 100 ohm? Like putting the battery inside of (for example tv remote) and then put the multimeter on both ends while its inside the remote?
@knurlgnar24 12 күн бұрын
Yes, perfectly valid so long as the device you are testing it in is the device you intend to use it in. Sometimes a battery will work just fine at a low drain in powering something like a clock, but not work at all powering something like a flashlight. If it doesn't work in the high drain device it's still a 'bad' battery but that matters little if it works well in the application you are using it in.

Yes, I still use this heater and have no major complaints. I think for many people a propane heater like a Buddy heater and a dozen or so 1lb propane tanks might be smaller and simpler to operate. They also don't emit kerosene odor. There's no arguing that a Kerosene heater like this one will give you a LOT more heat though over time. Storing a liquid fuel like Kerosene is trivial compared with propane.

According to the Suspicious Observer YT channel Space Weather news with the earth weakening magnetic core, these events will keep coming more frequently and more intense. I know parts of Australia have been getting flooding recently, too. I guess theres other factors, too. Some people won't be affected, and others will.

If you have a power supply that's DC 14.5 bulbs, and you have an inverter. That's supposed to put out a 110 to a 125 bolts. Why is it that the voltage is reading only a sea voltage on a multimeter? You should be reading a 115 to a 125 V, which does not especially when you have constant current, why is that??

I dont get it, charging and cycling your dead battery is supposed to fix it? Isnt that what everyone does with every dead battery, charge it then cycle it when it wont start your thing.
@knurlgnar24 18 күн бұрын
Most people attempt to charge the battery and either it won't take a charge or it doesn't work after charging and they throw it out. It's not as simple as just 'charge the battery' and most battery chargers are not capable of charging sulfated batteries even if the packaging specifically says it can. Controlled overcharge is required to desulfate. The cycling is only a part of it.

4 years ago our Buick had intermittent misfire/no start; local shop charged FORTUNE to replace crank sensor and ignition module. Flash forward today, exact same issues have returned from the grave. Swapped ICM, didn't fix Doing extensive looky loo, have noticed leaking gaskets top and side, the side of block is completely soaked in oil and fluid. Wondering if oils/fluids dripping downwards are shorting out the crank sensor Could that be feasible?
@knurlgnar24 20 күн бұрын
Oil might make the silicone seal swell allowing water intrusion but more likely will just prevent any corrosion because it's covered in oil. I wouldn't worry about the oil leaks unless you don't want stains on your concrete. That said valve cover gaskets are an easy job. Note that a bad crank sensor will NOT cause an intermittent misfire. The car will either run perfectly or randomly shut-off like you turned the key off and may or may not restart. An educated guess is that your issue is elsewhere. The connections between the ICM and the coils are a common cause of misfires on these vehicles but I'm guessing both were replaced as a unit.

I have a one bad cell lead acid battery 150ah. Maybe destroyed due to low acid+distilled water. I am charging it with my power supply set to 14.4V and 5.2A. Battery currently takes in 12.48V and 5.2A. it's bubbling a lot on all cells apart from the dead one. Should I lower the Amperage and keep it for a long time?
@knurlgnar24 Ай бұрын
As long as the temperature is kept in check and the plates stay covered with electrolyte you can charge at whatever current you're comfortable with, though 5.2A seems on the high side. From what you describe it sounds to me that you have a shorted cell which unfortunately can't be recovered without mechanically repairing the defect. I don't mess with battery internals and wouldn't recommend it outside a laboratory/industrial environment due to the hazards so I can't help you there.

In an exposed environment such as under a car's hood, I would crimp and solder. Crimping makes the electrical connection and solder seals the connection from water and dust intrusion. I've seen exposed crimped battery cable connections almost breaking aprart due to corrosion. I've never had a problem with rosin flux corrosion. Acid flux is a different and corrosive flux. That's why today's battery cable clamps are molded around the cable wires as a single unit. The slighest amount of resistance can drop the battery voltage at the starter to the point tha it can't turn over the engine. That can lead to the misdiagnosis as a bad battery.

Yes, I've tried it a couple of times to reform batteries. It didn't work for me but it also didn't seem to cause any damage to performance. I suspect the life will be affected negatively however.

I have an Optima battery, and I have tried multiple chargers with supposed restoration functions, which have done almost nothing. I am using a similar power supply and it is only taking a charge at 30 Volts. Lower voltages do nothing. I have found Optima batteries are difficult to recover when fully discharged. Some of my fancy chargers leave the battery at a lower voltage after charging or attempting restoration. Battery is only warm not hot, but higher temperatures help to dissolve lead sulfate.
@knurlgnar24 2 ай бұрын
Higher battery temperatures definitely help the process but make thermal runaway more likely which is why I don't recommend it. If after a controlled overcharge for an extended period the battery still won't accept a charge at normal voltages then it's probably time to recycle it and get a new one.

@@knurlgnar24 I suspect what happens to the discharged Optima Batteries during charging is a layer of gas forms over the lead plates and can't escape into the gel. I had one go dead during the COVID lockdown. A dome light was left on, and the battery went dead. I tried every trick to recharge it with no success. It sat in the garage for a few months, and then, long after I had replaced it, It took a charge. Very annoying not fond of Optima batteries after using them.

I’ve got a few rv / marine deep cycle batteries. They are both at 12.3 resting. With them being deep cycle batteries and not crank amp batteries- would these be ok to run in an enclosed trailer with a renogy dc to dc charger that’s connected to my pickup battery through 2GA wire. (Long jumper cables.) I’m trying to have power for 3 makita chargers and led lights inside the trailer. I have them hooked up to a small 2amp charger and I’m going to check them again tomorrow. I also have an old Napa brand charger on wheels that has the low 6/12v 2/4 amp charge, 40 amp, 80 amp/ 225 amp for jump start. Should I hook them up to that charger?
