See full version: Car Fan Still On When Engine is Turned Off
When the engine is running, the coolant circulates and flows to the radiator, where heat is dissipated. When the engine is turned off, the coolant doesn't circulate, and the heat stays trapped, therefore prolonging the engine from cooling. Running cooling fans help cool down the engine even after you turn off the car.
You park your car, turn off the ignition and start walking away. Then you notice the engine cooling fan is still running even though the car is turned off.
It is ok for the engine cooling fan to keep running for a few minutes after turning off the car. Your car fan will run for a few minutes after you turn off the car then turn it off.
This is normal in many vehicles, such as BMW or Mercedes-Benz. The radiator fan may run up to five minutes and sometimes longer.
Unless there is an electrical issue, it may stay on all the time until it drains the battery. more
If your cooling fan runs for over 10 minutes after turning off the engine, you may have a problem that needs to be fixed. [links]
First of all, don't panic. That only makes it worse. Really.
“Most standby generators operate that way,” Tobias said. “You'll know because standby generators need to be installed by pros.” here
Generators come in two flavors: portable and standby.
“Check the wattage to get an estimate of how many appliances the generator can run, the quality and consistency of the power it produces, and, of course, how long it'll run,” said Tobias Sommer, owner of Generators For Sale in Omaha.
“So they're used to run key appliances, rather than power everything,” Tobias said.
You should also make sure you've got enough fuel on hand, whether your generator is already running or not. Show your generator some love – give it a cool-down break every 24 hours until the power comes back.
We here have 2 ways for you to get the battery capaicty. here
The boss just want a cheap and small battery with it, but with no further information on how long does the end customer wants, how small can it be.
Another example: 12V 60Ah battery pack to power 220V 100W light
Working time: 12V*60Ah*0.9/100W=6.48 H here
so that’s 1855 Wh/ 11.1V=167Ah
take 103450 battery cell for example (T=10mm, W=34mm, L=50mm)
that’s 10*34*50*0.1=1700, in reality, it’s about 1800mAh or more. [links]
With new transducer cable in the console where it was needed, it was now a case of pulling the old one back out. This wasn't too hard once all the cabling was loose and out it came. The next thing to do was remove the speedo and hour-meter that were positioned where the new sounder would sit. more
If your sounder is sluggish and last century, it may be time to upgrade. If this sounds like you, then the latest sounders may make a world of difference - you are out on the water, trying to see what's on the bottom at a new found hotspot just marked. Only, when you look at the GPS combo to see if you are on the mark, it's clear you just flew over it. Worse, you can't see the bottom because the screen takes too long to rotate to the right view. more
Things got a bit tough and I needed to unscrew the floor on the other side of the console, as the rope and plug got jammed. Pulling the foam out, then reaching under the console is how I had to get through. Then success when the cable was through and hanging out the console.
Using the black and white one just doesn't compare to what this unit displays. If you are thinking of buying a new sounder the only way to go is colour full stop. It just allows you to really see what is going on down below with so much detail.
These were successfully removed with not much fuss, being sure to put the wires that came off the back of the gauges back where they came from. With two holes left over, I had a plate made up to cover them. Fortunately my mate is great with metal and cut me a piece of stainless plate. Mounting the plate in place wasn't too hard and by using stainless it looks great and will last forever. With the holes covered, it was time to set where the sounder needed to be positioned, then drill the hole and screw it into place. It didn't take too long and being firmly in place and secure it looked really neat on the stainless steel plate. more
